treewide: Switch printk users from %pf and %pF to %ps and %pS, respectively
%pF and %pf are functionally equivalent to %pS and %ps conversion specifiers. The former are deprecated, therefore switch the current users to use the preferred variant. The changes have been produced by the following command: git grep -l '%p[fF]' | grep -v '^\(tools\|Documentation\)/' | \ while read i; do perl -i -pe 's/%pf/%ps/g; s/%pF/%pS/g;' $i; done And verifying the result.

Since the first one, we've added basic unit testing of the three system calls, that resides in liburing like the other unit tests that we have so far. It'll take a while to get full coverage of it, but we're working towards it. I've also added two basic test programs to tools/io_uring. One uses the raw interface and has support for all the various features that io_uring supports outside of standard IO, like fixed files, fixed IO buffers, and polled IO. The other uses the liburing API, and is a simplified version of cp(1). This adds support for a new IO interface, io_uring. io_uring allows an application to communicate with the kernel through two rings, the submission queue (SQ) and completion queue (CQ) ring. This allows for very efficient handling of IOs, see the v5 posting for some basic numbers: https://lore.kernel.org/linux-block/20190116175003.17880-1-axboe@kernel.dk/ Outside of just efficiency, the interface is also flexible and extendable, and allows for future use cases like the upcoming NVMe key-value store API, networked IO, and so on. It also supports async buffered IO, something that we've always failed to support in the kernel. Outside of basic IO features, it supports async polled IO as well. This particular feature has already been tested at Facebook months ago for flash storage boxes, with 25-33% improvements. It makes polled IO actually useful for real world use cases, where even basic flash sees a nice win in terms of efficiency, latency, and performance. These boxes were IOPS bound before, now they are not. This series adds three new system calls. One for setting up an io_uring instance (io_uring_setup(2)), one for submitting/completing IO (io_uring_enter(2)), and one for aux functions like registrating file sets, buffers, etc (io_uring_register(2)). Through the help of Arnd, I've coordinated the syscall numbers so merge on that front should be painless. Jon did a writeup of the interface a while back, which (except for minor details that have been tweaked) is still accurate. Find that here: https://lwn.net/Articles/776703/ Huge thanks to Al Viro for helping getting the reference cycle code correct, and to Jann Horn for his extensive reviews focused on both security and bugs in general. There's a userspace library that provides basic functionality for applications that don't need or want to care about how to fiddle with the rings directly. It has helpers to allow applications to easily set up an io_uring instance, and submit/complete IO through it without knowing about the intricacies of the rings. It also includes man pages (thanks to Jeff Moyer), and will continue to grow support helper functions and features as time progresses. Find it here: git://git.kernel.dk/liburing Fio has full support for the raw interface, both in the form of an IO engine (io_uring), but also with a small test application (t/io_uring) that can exercise and benchmark the interface" * tag 'io_uring-2019-03-06' of git://git.kernel.dk/linux-block: io_uring: add a few test tools io_uring: allow workqueue item to handle multiple buffered requests io_uring: add support for IORING_OP_POLL io_uring: add io_kiocb ref count io_uring: add submission polling io_uring: add file set registration net: split out functions related to registering inflight socket files io_uring: add support for pre-mapped user IO buffers block: implement bio helper to add iter bvec pages to bio io_uring: batch io_kiocb allocation io_uring: use fget/fput_many() for file references fs: add fget_many() and fput_many() io_uring: support for IO polling io_uring: add fsync support Add io_uring IO interface |

This is the bulk of GPIO changes for the v5.1 cycle:
Core changes: - The big change this time around is the irqchip handling in the qualcomm pin controllers, closely coupled with the gpiochip. This rework, in a classic fall-between-the-chairs fashion has been sidestepped for too long. The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms have been rewritten to use hierarchical irqchip. This creates the base from which I intend to gradually pull support for hierarchical irqchips into the gpiolib irqchip helpers to cut down on duplicate code. We have too many hacks in the kernel because people have been working around the missing hierarchical irqchip for years, and once it was there, noone understood it for a while. We are now slowly adapting to using it. This is why this pull requests include changes to MFD, SPMI, IRQchip core and some ARM Device Trees pertaining to the Qualcomm chip family. Since Qualcomm have so many chips and such large deployments it is paramount that this platform gets this right, and now it (hopefully) does. - Core support for pull-up and pull-down configuration, also from the device tree. When a simple GPIO chip support a "off or on" pull-up or pull-down resistor, we provide a way to set this up using machine descriptors or device tree. If more elaborate control of pull up/down (such as resistance shunt setting) is required, drivers should be phased over to use pin control. We do not yet provide a userspace ABI for this pull up-down setting but I suspect the makers are going to ask for it soon enough.

This rework, in a classic fall-between-the-chairs fashion has been sidestepped for too long. The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms have been rewritten to use hierarchical irqchip. This creates the base from which I intend to gradually pull support for hierarchical irqchips into the gpiolib irqchip helpers to cut down on duplicate code. We have too many hacks in the kernel because people have been working around the missing hierarchical irqchip for years, and once it was there, noone understood it for a while. We are now slowly adapting to using it. This is why this pull requests include changes to MFD, SPMI, IRQchip core and some ARM Device Trees pertaining to the Qualcomm chip family. Since Qualcomm have so many chips and such large deployments it is paramount that this platform gets this right, and now it (hopefully) does. - Core support for pull-up and pull-down configuration, also from the device tree. When a simple GPIO chip supports an "off or on" pull-up or pull-down resistor, we provide a way to set this up using machine descriptors or device tree. If more elaborate control of pull up/down (such as resistance shunt setting) is required, drivers should be phased over to use pin control. We do not yet provide a userspace ABI for this pull up-down setting but I suspect the makers are going to ask for it soon enough.

A couple of bug fixes and a bunch of code cleanup:
* Fix a use after free error in a certain error situation. * Fix some flag handling issues in the SSIF (I2C) IPMI driver. * A bunch of cleanups, spacing issues, converting pr_xxx to dev_xxx, use standard UUID handling, and some other minor stuff. * The IPMI code was creating a platform device if none was supplied. Instead of doing that, have every source that creates an IPMI device supply a device struct. This fixes several issues,including a crash in one situation, and cleans things up a bit. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE/Q1c5nzg9ZpmiCaGYfOMkJGb/4EFAlx+qm8ACgkQYfOMkJGb /4F8rxAAmzPgNowsV6T0T9ZHg35XRx31vjPyrCZsbzBv0ahSr6mIwoz41iZAz1z8 bGjJJ8LA6oqfG9PsolUMc8RsiHXOlCXR2qpcx7r6N1Ptj/7VNdy9UneIl5UwnxhP 1mGkWJeKYQn3tXVa8PjzfX9kZ3gxcooL9q+0+m2E6O5M/ldzUvWDGXRfoVD+Uy88 RoPd3AeUnaIBDoB42l5a9EzPr+xXVKYSPl7WLEgV4GTwWRANvFP88PSXOenzo35b G08Yq6+u1M1QY/HJLLtvanHWpkBrHGLr+XTdXKAxKgV40s2flL4xBSfYWF8RFLCW R74HXwSOSvpZEhROrleaj2GcL1DsJhQj5Q+DsYAIyMJSkavPtFZU2TRL+nOUoe39 wJdS5F0i7qhnNPtj0Iatz9zOwY5apT5vj7/MAEXIQi2t+p1m7ado1kw7CDaQsTOK ONzhlxCZ6b6rvdpJ7hH8u1AAejRoZ8tq9rAdsKSJvgTPiDrtLDlouPkAQCJpl7Ub VsByzrXeL2a6yEW9W5V2LH2UXandRAKguzvnYDOEbY5bVOmQmEaoDWTvoC5jRr6K MRobCgC96UpNgY4SXJSoZunrFjuGJR0CN66BJd52afcxEM/iu50Z8+DJ92KnDjhY E8XVvC5fXH6EMF1yDIt51GiDyHYQXX1TaNArFuFZWaEJ8e2gT6M= =LSch -----END PGP SIGNATURE----- Merge tag 'for-linus-5.1' of git://github.com/cminyard/linux-ipmi Pull IPMI updates from Corey Minyard: "A couple of bug fixes and a bunch of code cleanup: - Fix a use after free error in a certain error situation. - Fix some flag handling issues in the SSIF (I2C) IPMI driver. - A bunch of cleanups, spacing issues, converting pr_xxx to dev_xxx, use standard UUID handling, and some other minor stuff. - The IPMI code was creating a platform device if none was supplied.

gpio: gpio-omap: fix level interrupt idling
Tony notes that the GPIO module does not idle when level interrupts are in use, as the wakeup appears to get stuck. After extensive investigation, it appears that the wakeup will only be cleared if the interrupt status register is cleared while the interrupt is enabled. However, we are currently clearing it with the interrupt disabled for level-based interrupts. It is acknowledged that this observed behaviour conflicts with a statement in the TRM: CAUTION After servicing the interrupt, the status bit in the interrupt status register (GPIOi.GPIO_IRQSTATUS_0 or GPIOi.GPIO_IRQSTATUS_1) must be reset and the interrupt line released (by setting the corresponding bit of the interrupt status register to 1) before enabling an interrupt for the GPIO channel in the interrupt-enable register (GPIOi.GPIO_IRQSTATUS_SET_0 or GPIOi.GPIO_IRQSTATUS_SET_1) to prevent the occurrence of unexpected interrupts when enabling an interrupt for the GPIO channel. However, this does not appear to be a practical problem. Further, as reported by Grygorii Strashko <grygorii.strashko@ti.com>, the TI Android kernel tree has an earlier similar patch as "GPIO: OMAP: Fix the sequence to clear the IRQ status" saying: if the status is cleared after disabling the IRQ then sWAKEUP will not be cleared and gates the module transition When we unmask the level interrupt after the interrupt has been handled, enable the interrupt and only then clear the interrupt. If the interrupt is still pending, the hardware will re-assert the interrupt status. Should the caution note in the TRM prove to be a problem, we could use a clear-enable-clear sequence instead.

include/linux/relay.h: fix percpu annotation in struct rchan
The percpu member of this structure is declared as:
struct ... ** __percpu member;
So its type is:
__percpu pointer to pointer to struct ...
But looking at how it's used, its type should be:
pointer to __percpu pointer to struct ...
and it should thus be declared as:
struct ... * __percpu *member;
So fix the placement of '__percpu' in the definition of this
structures.
This silents a few Sparse's warnings like:
warning: incorrect type in initializer (different address spaces)
expected void const [noderef] <asn:3> *__vpp_verify
got struct sched_domain **

mm: create the new vm_fault_t type
Page fault handlers are supposed to return VM_FAULT codes, but some drivers/file systems mistakenly return error numbers. Now that all drivers/file systems have been converted to use the vm_fault_t return type, change the type definition to no longer be compatible with 'int'. By making it an unsigned int, the function prototype becomes incompatible with a function which returns int. Sparse will detect any attempts to return a value which is not a VM_FAULT code. VM_FAULT_SET_HINDEX and VM_FAULT_GET_HINDEX values are changed to avoid conflict with other VM_FAULT codes.

arch: simplify several early memory allocations
There are several early memory allocations in arch/ code that use memblock_phys_alloc() to allocate memory, convert the returned physical address to the virtual address and then set the allocated memory to zero. Exactly the same behaviour can be achieved simply by calling memblock_alloc(): it allocates the memory in the same way as memblock_phys_alloc(), then it performs the phys_to_virt() conversion and clears the allocated memory. Replace the longer sequence with a simpler call to memblock_alloc().

openrisc: simplify pte_alloc_one_kernel()
The pte_alloc_one_kernel() function allocates a page using __get_free_page(GFP_KERNEL) when mm initialization is complete and memblock_phys_alloc() on the earlier stages. The physical address of the page allocated with memblock_phys_alloc() is converted to the virtual address and in the both cases the allocated page is cleared using clear_page(). The code is simplified by replacing __get_free_page() with get_zeroed_page() and by replacing memblock_phys_alloc() with memblock_alloc().

powerpc: prefer memblock APIs returning virtual address
Patch series "memblock: simplify several early memory allocation", v4. These patches simplify some of the early memory allocations by replacing usage of older memblock APIs with newer and shinier ones. Quite a few places in the arch/ code allocated memory using a memblock API that returns a physical address of the allocated area, then converted this physical address to a virtual one and then used memset(0) to clear the allocated range. More recent memblock APIs do all the three steps in one call and their usage simplifies the code. It's important to note that regardless of API used, the core allocation is nearly identical for any set of memblock allocators: first it tries to find a free memory with all the constraints specified by the caller and then falls back to the allocation with some or all constraints disabled. The first three patches perform the conversion of call sites that have exact requirements for the node and the possible memory range. The fourth patch is a bit one-off as it simplifies openrisc's implementation of pte_alloc_one_kernel(), and not only the memblock usage. The fifth patch takes care of simpler cases when the allocation can be satisfied with a simple call to memblock_alloc(). The sixth patch removes one-liner wrappers for memblock_alloc on arm and unicore32, as suggested by Christoph. This patch (of 6): There are a several places that allocate memory using memblock APIs that return a physical address, convert the returned address to the virtual address and frequently also memset(0) the allocated range. Update these places to use memblock allocators already returning a virtual address. Use memblock functions that clear the allocated memory instead of calling memset(0) where appropriate. The calls to memblock_alloc_base() that were not followed by memset(0) are replaced with memblock_alloc_try_nid_raw(). Since the latter does not panic() when the allocation fails, the appropriate panic() calls are added to the call sites.

lib/lzo: implement run-length encoding
Patch series "lib/lzo: run-length encoding support", v5. Following on from the previous lzo-rle patchset: https://lkml.org/lkml/2018/11/30/972 This patchset contains only the RLE patches, and should be applied on top of the non-RLE patches ( https://lkml.org/lkml/2019/2/5/366 ). Previously, some questions were raised around the RLE patches. I've done some additional benchmarking to answer these questions. In short: - RLE offers significant additional performance (data-dependent) - I didn't measure any regressions that were clearly outside the noise One concern with this patchset was around performance - specifically, measuring RLE impact separately from Matt Sealey's patches (CTZ & fast copy). I have done some additional benchmarking which I hope clarifies the benefits of each part of the patchset. Firstly, I've captured some memory via /dev/fmem from a Chromebook with many tabs open which is starting to swap, and then split this into 4178 4k pages. I've excluded the all-zero pages (as zram does), and also the no-zero pages (which won't tell us anything about RLE performance). This should give a realistic test dataset for zram. What I found was that the data is VERY bimodal: 44% of pages in this dataset contain 5% or fewer zeros, and 44% contain over 90% zeros (30% if you include the no-zero pages). This supports the idea of special-casing zeros in zram. Next, I've benchmarked four variants of lzo on these pages (on 64-bit Arm at max frequency): baseline LZO; baseline + Matt Sealey's patches (aka MS); baseline + RLE only; baseline + MS + RLE. Numbers are for weighted roundtrip throughput (the weighting reflects that zram does more compression than decompression). https://drive.google.com/file/d/1VLtLjRVxgUNuWFOxaGPwJYhl_hMQXpHe/view?usp=sharing Matt's patches help in all cases for Arm (and no effect on Intel), as expected. RLE also behaves as expected: with few zeros present, it makes no difference; above ~75%, it gives a good improvement (50 - 300 MB/s on top of the benefit from Matt's patches). Best performance is seen with both MS and RLE patches. Finally, I have benchmarked the same dataset on an x86-64 device. Here, the MS patches make no difference (as expected); RLE helps, similarly as on Arm. There were no definite regressions; allowing for observational error, 0.1% (3/4178) of cases had a regression > 1 standard deviation, of which the largest was 4.6% (1.2 standard deviations). I think this is probably within the noise. https://drive.google.com/file/d/1xCUVwmiGD0heEMx5gcVEmLBI4eLaageV/view?usp=sharing One point to note is that the graphs show RLE appears to help very slightly with no zeros present! This is because the extra code causes the clang optimiser to change code layout in a way that happens to have a significant benefit. Taking baseline LZO and adding a do-nothing line like "__builtin_prefetch(out_len);" immediately before the "goto next" has the same effect. So this is a real, but basically spurious effect - it's small enough not to upset the overall findings. This patch (of 3): When using zram, we frequently encounter long runs of zero bytes. This adds a special case which identifies runs of zeros and encodes them using run-length encoding. This is faster for both compression and decompresion. For high-entropy data which doesn't hit this case, impact is minimal. Compression ratio is within a few percent in all cases. This modifies the bitstream in a way which is backwards compatible (i.e., we can decompress old bitstreams, but old versions of lzo cannot decompress new bitstreams).
