linux/kernel.h: split *_MAX and *_MIN macros into <linux/limits.h>
<linux/kernel.h> tends to be cluttered because we often put various sort of unrelated stuff in it. So, we have split out a sensible chunk of code into a separate header from time to time. This commit splits out the *_MAX and *_MIN defines. The standard header <limits.h> contains various MAX, MIN constants including numerial limits. [1] I think it makes sense to move in-kernel MAX, MIN constants into include/linux/limits.h. We already have include/uapi/linux/limits.h to contain some user-space constants. I changed its include guard to _UAPI_LINUX_LIMITS_H. This change has no impact to the user-space because scripts/headers_install.sh rips off the '_UAPI' prefix from the include guards of exported headers.

build_bug.h: add wrapper for _Static_assert
BUILD_BUG_ON() is a little annoying, since it cannot be used outside function scope. So one cannot put assertions about the sizeof() a struct next to the struct definition, but has to hide that in some more or less arbitrary function. Since gcc 4.6 (which is now also the required minimum), there is support for the C11 _Static_assert in all C modes, including gnu89. So add a simple wrapper for that. _Static_assert() requires a message argument, which is usually quite redundant (and I believe that bug got fixed at least in newer C++ standards), but we can easily work around that with a little macro magic, making it optional. For example, adding static_assert(sizeof(struct printf_spec) == 8); in vsprintf.c and modifying that struct to violate it, one gets ./include/linux/build_bug.h:78:41: error: static assertion failed: "sizeof(struct printf_spec) == 8" #define __static_assert(expr, msg, ...) _Static_assert(expr, "" msg "") godbolt.org suggests that _Static_assert() has been support by clang since at least 3.0.0.

<linux/kernel.h>: drop the gcc-3.3 'const' hack in roundup()
The single quotation marks around "const" were causing a documentation markup warning with reST. Instead of fixing that warning, just delete that comment line and the gcc-3.3 hack of using "const" in the roundup() macro since gcc-3.3 is no longer supported for kernel builds. I did around 20 different $arch builds with no problems, but we'll just have to see if this causes problems for anyone else out there.

kernel/panic.c: taint: fix debugfs_simple_attr.cocci warnings
Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE for debugfs files. Semantic patch information: Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file() imposes some significant overhead as compared to DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe(). Generated by: scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci The _unsafe() part suggests that some of them "safeness responsibilities" are now panic.c responsibilities. The patch is OK since panic's clear_warn_once_fops struct file_operations is safe against removal, so we don't have to use otherwise necessary debugfs_file_get()/debugfs_file_put().

powerpc updates for 5.1
Notable changes:
- Enable THREAD_INFO_IN_TASK to move thread_info off the stack.
- A big series from Christoph reworking our DMA code to use more of the generic
infrastructure, as he said:
"This series switches the powerpc port to use the generic swiotlb and
noncoherent dma ops, and to use more generic code for the coherent direct
mapping, as well as removing a lot of dead code."
- Increase our vmalloc space to 512T with the Hash MMU on modern CPUs, allowing
us to support machines with larger amounts of total RAM or distance between
nodes.
- Two series from Christophe, one to optimise TLB miss handlers on 6xx, and
another to optimise the way STRICT_KERNEL_RWX is implemented on some 32-bit
CPUs.
- Support for KCOV coverage instrumentation which means we can run syzkaller
and discover even more bugs in our code.
And as always many clean-ups, reworks and minor fixes etc.

RISC-V Patches for the 5.1 Merge Window, Part 1
This contains the vast majority of the RISC-V patches for this merge
window. It includes:
* A handful of cleanups to our kernel prints, most of which are things I
should have caught the first time.
* We now provide an HWCAP that contains the ISA extensions that all
enabled processors support, as supposed to just looking at the first
enabled processor.
* We no longer spin forever waiting for all harts to boot.
* A fixmap implementation, which is coupled to some cleanups in our MM
code.
The only outstanding patches I know of right now are Vincent Chen's
patches to fix c.ebreak handling in the kernel, the v2 of which was
posted this morning. I'd like those in the MW, but I didn't want to
hold up everything else. The patch set is based on top of my last fixes
submission, but I've tested it with a conflict-free merge from v5.0.
I'm doing this rather than my "just go rebase everything" flow due to a
discussion with Linus, but if I misunderstood then just let me know and
I'll do something else. It's also the first time I've taken a PR into
my own tree, so let me know if I screwed that one up.
I've used my standard testing flow (QEMU in Fedora), but now that we're
starting to get the kernel in better shape I think it's time to impose
some more testing here -- specifically I'm going to require that patches
boot on the HiFive Unleashed because we're getting to the point where we
can actually expect that to work. I haven't done that for this tag, but
I'm going to do it for future ones.
I know the board is a bit expensive and not everyone has one, but if
I've sent you a free one and your patches break the boot then I'm going
to yell at you :). If you don't have one then please indicate how you
tested in your cover letter, and if you have a board then please add
your Tested-by to patches if they work for your testing flow.

One small fix and one clean up
A small fix Pavel sent me back in august was accidentally lost due to it being placed with some other patches that failed some tests, and was rebased out of my local tree. Which was a regression that caused event filters not to handle negative numbers. The clean up is from Masami that realized that the code in kprobes that calls probe_mem_read() wrapper, which is to be used in code used by both kprobes and uprobes, was only in code for kprobes. It should not use the wrapper there, but instead call probe_kernel_read() directly. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCXH2gZRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qrTyAQC+dfxfyS32BWpGOwZbUIHGYYHtnpEB 7bIQzXy2q8r4YQD/UGJ0qoHur1gSMEIVjhIM0Qow4VepqqhthIAV/1iVbgU= =F9yc -----END PGP SIGNATURE----- Merge tag 'trace-v5.0-pre' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix/cleanup from Steven Rostedt: "This is a "pre-pull".

Changes for Linux 5.1:
- Fix online fsck to handle inode btrees correctly on 64k block
filesystems.
- Teach online fsck to check directory and attribute names for invalid
characters.
- Miscellanous fixes for online fsck.
- Introduce a new panic mask so that we can halt immediately on
metadata corruption (for debugging purposes)
- Fix a block mapping race during writeback.
- Cache unlinked inode list backrefs in memory to speed up list
processing.
- Separate the bnobt/cntbt and inobt/finobt buffer verifiers so that we
can detect crosslinked btrees.
- Refactor magic number verification so that we can standardize it.
- Strengthen ondisk metadata structure offset build time verification.
- Fix a memory corruption problem in the listxattr code.
- Fix a shutdown problem during log recovery due to unreserved finobt
expansion.
- Fix a referential integrity problem where O_TMPFILE inodes were put on
the unlinked list with nlink > 0 which would cause asserts during log
recovery if the system went down immediately.
- Refactor the delayed allocation allocator to be more clever about the
possibility that its mapping might be stale.
- Various fixes to the copy on write mechanism.
- Make CoW preallocation suitable for use even with writes that wouldn't
otherwise require it.
- Refactor an internal API.
- Fix some statx implementation bugs.
- Fix miscellaneous compiler and static checker complaints.

Merge tag 'for-5.1-part1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"This contains usual mix of new features, core changes and fixes; full
list below. I'm planning second pull request, with a few more fixes
that arrived recently but too close to merge window, will send it next
week.
New features:
- support zstd compression levels
- new ioctl to unregister a device from the module (ie. reverse of
device scan)
- scrub prints a message to log when it's about to start or finish
Core changes:
- qgroups can now skip part of a tree that does not get updated
during relocation, because this does not affect the quota
accounting, estimated speedup in run time is about 20%
- the compression workspace management had to be enhanced due to zstd
requirements
- various enospc fixes, when there's high fragmentation the
over-reservation can cause ENOSPC that might not happen after a
flush, in such cases try to wait if the situation improves
Fixes:
- various ioctls could overwrite previous return value if
copy_to_user fails, fix this so the original error is reported
- more reclaim vs GFP_KERNEL fixes
- other cleanups and refactoring
- fix a (valid) lockdep warning in a test when device replace is
destroying worker threads
- make qgroup async transaction commit more aggressive, this avoids
some 'quota limit reached' errors if there are not enough data to
trigger transaction in order to flush
- fix deadlock between snapshot deletion and quotas when backref
walking is called from context that already holds the same locks
- fsync fixes:
- fix fsync after succession of renames of different files
- fix fsync after succession of renames and unlink/rmdir"

sound updates for 5.1
We had again a busy development cycle with many new drivers as well as
lots of core improvements / cleanups. Let's go for highlights:
ALSA core:
- PCM locking scheme was refactored for reducing a global rwlock
- PCM suspend is handled in the device type PM ops now; lots of
explicit calls were reduced by this action
- Cleanups about PCM buffer preallocation calls
- Kill NULL device object in memory allocations
- Lots of procfs API cleanups
ASoC core:
- Support for only powering up channels that are actively being used
- Cleanups / fixes of topology API
ASoC drivers:
- MediaTek BTCVSD for a Bluetooth radio chip, which is the first such
driver we've had upstream!
- Quite a few improvements to simplify the generic card drivers,
especially the merge of the SCU cards into the main generic drivers
- Lots of fixes for probing on Intel systems to follow more standard
styles
- A big refresh and cleanup of the Samsung drivers
- New drivers: Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341
and CS35L26, Google ChromeOS embedded controllers, Ingenic JZ4725B,
MediaTek BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328,
Spreadtrum DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM
formatters
ALSA drivers:
- Improvements of Tegra HD-audio controller driver for supporting new
chips
- HD-audio codec quirks for ALC294 S4 resume, ASUS laptop, Chrome
headset button support and Dell workstations
- Improved DSD support on USB-audio
- Quirk for MOTU MicroBook II USB-audio
- Support for Fireface UCX support and Solid State Logic Duende

io_uring: allow workqueue item to handle multiple buffered requests
Right now we punt any buffered request that ends up triggering an -EAGAIN to an async workqueue. This works fine in terms of providing async execution of them, but it also can create quite a lot of work queue items. For sequentially buffered IO, it's advantageous to serialize the issue of them. For reads, the first one will trigger a read-ahead, and subsequent request merely end up waiting on later pages to complete. For writes, devices usually respond better to streamed sequential writes. Add state to track the last buffered request we punted to a work queue, and if the next one is sequential to the previous, attempt to get the previous work item to handle it. We limit the number of sequential add-ons to the a multiple (8) of the max read-ahead size of the file. This should be a good number for both reads and wries, as it defines the max IO size the device can do directly. This drastically cuts down on the number of context switches we need to handle buffered sequential IO, and a basic test case of copying a big file with io_uring sees a 5x speedup.
