Performing vma lookups without taking the mm->mmap_sem is asking for
trouble. While doing the search, the vma in question can be modified or
even removed before returning to the caller. Take the lock (shared) in
order to avoid races while iterating through the vmacache and/or rbtree.
In addition, this guarantees that the address space will remain intact
during the CPU flushing.

We need a mechanism to tag ptes as being special, this indicates that no

with the pte. This is used by the fast_gup when operating on ptes as it
has no means to access VMAs (that also contain this information)
locklessly.
The L_PTE_SPECIAL bit is already allocated for LPAE, this patch modifies
pte_special and pte_mkspecial to make use of it, and defines
__HAVE_ARCH_PTE_SPECIAL.

For architectures without coherent DMA, memory for DMA may need to be
remapped with coherent attributes. Factor out the the remapping code from
arm and put it in a common location to reduce code duplication.
As part of this, the arm APIs are now migrated away from
ioremap_page_range to the common APIs which use map_vm_area for remapping.
This should be an equivalent change and using map_vm_area is more correct
as ioremap_page_range is intended to bring in io addresses into the cpu
space and not regular kernel managed memory.

ARCH_USES_NUMA_PROT_NONE was defined for architectures that implemented
_PAGE_NUMA using _PROT_NONE. This saved using an additional PTE bit and
relied on the fact that PROT_NONE vmas were skipped by the NUMA hinting
fault scanner. This was found to be conceptually confusing with a lot of
implicit assumptions and it was asked that an alternative be found.
Commit c46a7c81 "x86: define _PAGE_NUMA by reusing software bits on the
PMD and PTE levels" redefined _PAGE_NUMA on x86 to be one of the swap PTE
bits and shrunk the maximum possible swap size but it did not go far
enough. There are no architectures that reuse _PROT_NONE as _PROT_NUMA
but the relics still exist.
This patch removes ARCH_USES_NUMA_PROT_NONE and removes some unnecessary
duplication in powerpc vs the generic implementation by defining the types
the core NUMA helpers expected to exist from x86 with their ppc64
equivalent. This necessitated that a PTE bit mask be created that
identified the bits that distinguish present from NUMA pte entries but it
is expected this will only differ between arches based on _PAGE_PROTNONE.
The naming for the generic helpers was taken from x86 originally but ppc64
has types that are equivalent for the purposes of the helper so they are
mapped instead of duplicating code.

Pull networking updates from David Miller:
"Most notable changes in here:
1) By far the biggest accomplishment, thanks to a large range of
contributors, is the addition of multi-send for transmit. This is
the result of discussions back in Chicago, and the hard work of
several individuals.
Now, when the ->ndo_start_xmit() method of a driver sees
skb->xmit_more as true, it can choose to defer the doorbell
telling the driver to start processing the new TX queue entires.
skb->xmit_more means that the generic networking is guaranteed to
call the driver immediately with another SKB to send.
There is logic added to the qdisc layer to dequeue multiple
packets at a time, and the handling mis-predicted offloads in
software is now done with no locks held.
Finally, pktgen is extended to have a "burst" parameter that can
be used to test a multi-send implementation.
Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
virtio_net
Adding support is almost trivial, so export more drivers to
support this optimization soon.
I want to thank, in no particular or implied order, Jesper
Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
David Tat, Hannes Frederic Sowa, and Rusty Russell.
2) PTP and timestamping support in bnx2x, from Michal Kalderon.
3) Allow adjusting the rx_copybreak threshold for a driver via
ethtool, and add rx_copybreak support to enic driver. From
Govindarajulu Varadarajan.
4) Significant enhancements to the generic PHY layer and the bcm7xxx
driver in particular (EEE support, auto power down, etc.) from
Florian Fainelli.
5) Allow raw buffers to be used for flow dissection, allowing drivers
to determine the optimal "linear pull" size for devices that DMA
into pools of pages. The objective is to get exactly the
necessary amount of headers into the linear SKB area pre-pulled,
but no more. The new interface drivers use is eth_get_headlen().

by-hand duplicated implementations) by Alexander Duyck and Eric

7) Add Broadcom SF2 switch driver to DSA layer, from Florian

8) eBPF now can load programs via a system call and has an extensive

9) Major overhaul of the packet scheduler to use RCU in several major

As usual, this is the largest branch, though this time a little under
half of the total changes with 307 individual non-merge changesets.
The largest changes are the addition of new machines, in particular
the Tegra based Chromebook, the Renesas r8a7794 SoC, and DT support
for the old i.MX1 platform.
Other changes include
- at91: various sam9 and sama5 updates
- exynos: much extended Peach Pi/Pit (Chromebook 2) support
- keystone: new peripherals
- meson: added DT for meson6 SoC
- mvebu: new device support for Armada 370/375
- qcom: improved support for IPQ8064 and MSM8x60
- rockchip: much improved support for rk3288
- shmobile: lots of updates all over the place

This time around, the cleanup branch contains mostly code removal. A number
of board files for at91, imx and msm have become obsolete because of the
DT conversion and are now ready to be removed. The OMAP platform has
traditionally had its own DMA engine abstraction and as this is being
phased out, a lot of the original code is now unused and can be removed
as well.
S3C24xx can be simplified now that the restart code is a proper device
driver.
Finally, a number of cleanups in shmobile are done to prepare for
the addition of new code in other branches.

Pull ARM updates from Russell King:
"Included in these updates are:
- Performance optimisation to avoid writing the control register at
every exception.
- Use static inline instead of extern inline in ftrace code.
- Crypto ARM assembly updates for big endian
- Alignment of initrd/.init memory to page sizes when freeing to
ensure that we fully free the regions
- Add gcov support
- A couple of preparatory patches for VDSO support: use
_install_special_mapping, and randomize the sigpage placement above
stack.
- Add L2 ePAPR DT cache properties so that DT can specify the cache
geometry.
- Preparatory patch for FIQ (NMI) kernel C code for things like
spinlock lockup debug. Following on from this are a couple of my
patches cleaning up show_regs() and removing an unused (probably
since 1.x days) do_unexp_fiq() function.
- Use pr_warn() rather than pr_warning().
- A number of cleanups (smp, footbridge, return_address)"

Apart from the usual cleanups, here is the summary of new features:
- s390 moves closer towards host large page support
- PowerPC has improved support for debugging (both inside the guest and
via gdbstub) and support for e6500 processors
- ARM/ARM64 support read-only memory (which is necessary to put firmware
in emulated NOR flash)
- x86 has the usual emulator fixes and nested virtualization improvements
(including improved Windows support on Intel and Jailhouse hypervisor
support on AMD), adaptive PLE which helps overcommitting of huge guests.
Also included are some patches that make KVM more friendly to memory
hot-unplug, and fixes for rare caching bugs.
Two patches have trivial mm/ parts that were acked by Rik and Andrew.

hwreg_present() and hwreg_write() temporarily change the VBR register to
another vector table. This table contains a valid bus error handler
only, all other entries point to arbitrary addresses.
If an interrupt comes in while the temporary table is active, the
processor will start executing at such an arbitrary address, and the
kernel will crash.
While most callers run early, before interrupts are enabled, or
explicitly disable interrupts, Finn Thain pointed out that macsonic has
one callsite that doesn't, causing intermittent boot crashes.
There's another unsafe callsite in hilkbd.
Fix this for good by disabling and restoring interrupts inside
hwreg_present() and hwreg_write().
Explicitly disabling interrupts can be removed from the callsites later.
