An SMI to a halted VCPU must wake it up, hence a VCPU with a pending
SMI must be considered runnable.

Otherwise, two copies (one of them never populated and thus bogus)
are allocated for the regular and SMM address spaces. This breaks
SMM with EPT but without unrestricted guest support, because the
SMM copy of the identity page map is all zeros.
By moving the allocation to the caller we also remove the last
vestiges of kernel-allocated memory regions (not accessible anymore
in userspace since commit b74a07beed0e, "KVM: Remove kernel-allocated
memory regions", 2010-06-21); that is a nice bonus.

The next patch will make x86_set_memory_region fill the
userspace_addr. Since the struct is not used untouched
anymore, it makes sense to build it in x86_set_memory_region
directly; it also simplifies the callers.

Unlike shash algorithms, ahash drivers must implement export
and import as their descriptors may contain hardware state and
cannot be exported as is. Unfortunately some ahash drivers did
not provide them and end up causing crashes with algif_hash.
This patch adds a check to prevent these drivers from registering
ahash algorithms until they are fixed.

Commit 7a5692e6e533 ("arch/powerpc: provide zero_bytemask() for
big-endian") added a call to __fls() in our word-at-a-time.h. That was
fine for the kernel build but missed the fact that we also use
word-at-a-time.h in a userspace test.
Pulling in the kernel version of __fls() gets messy, so just define our
own, it's unlikely to change often.

MINSIGSTKSZ and SIGSTKSZ for ARM64 are not correctly set in latest kernel.
This patch fixes this issue.
This issue is reported in LTP (testcase: sigaltstack02.c).
Testcase failed when sigaltstack() called with stack size "MINSIGSTKSZ - 1"
Since in Glibc-2.22, MINSIGSTKSZ is set to 5120 but in kernel
it is set to 2048 so testcase gets failed.
Testcase Output:
sigaltstack02 1 TPASS : stgaltstack() fails, Invalid Flag value,errno:22
sigaltstack02 2 TFAIL : sigaltstack() returned 0, expected -1,errno:12

Commit df057cc7b4fa ("arm64: errata: add module build workaround for
erratum #843419") sets CFLAGS_MODULE to ensure that the large memory
model is used by the compiler when building kernel modules.
However, CFLAGS_MODULE is an environment variable and intended to be
overridden on the command line, which appears to be the case with the
Ubuntu kernel packaging system, so use KBUILD_CFLAGS_MODULE instead.

Now that the NFS server advertises a maximum payload size of 1MB
for RPC/RDMA again, it crashes in svc_process_common() when NFS
client sends a 1MB NFS WRITE on an NFS/RDMA mount.
The server has set up a 259 element array of struct page pointers
in rq_pages[] for each incoming request. The last element of the
array is NULL.
When an incoming request has been completely received,
rdma_read_complete() attempts to set the starting page of the
incoming page vector:
rqstp->rq_arg.pages = &rqstp->rq_pages[head->hdr_count];
and the page to use for the reply:
rqstp->rq_respages = &rqstp->rq_arg.pages[page_no];
But the value of page_no has already accounted for head->hdr_count.
Thus rq_respages now points past the end of the incoming pages.
For NFS WRITE operations smaller than the maximum, this is harmless.
But when the NFS WRITE operation is as large as the server's max
payload size, rq_respages now points at the last entry in rq_pages,
which is NULL.
Fixes: cc9a903d915c ('svcrdma: Change maximum server payload . . .')

git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes
Nothing too crazy here, a couple of regression fixes + runpm/fbcon
race fix.
* 'linux-4.3' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/nouveau/bios: fix OF loading
drm/nouveau/fbcon: take runpm reference when userspace has an open fd
drm/nouveau/nouveau: Disable AGP for SiS 761
drm/nouveau/display: allow up to 16k width/height for fermi+
drm/nouveau/bios: translate devinit pri/sec i2c bus to internal identifiers

Currently OF bios load fails for a few reasons:
- checksum failure
- bios size too small
- no PCIR header
- bios length not a multiple of 4
In this change, we resolve all of the above by ignoring any checksum
failures (since OF VBIOS tends not to have a checksum), and faking the
PCIR data when loading from OF.

We need to do this in order to prevent accesses to the device while it's
powered down. Userspace may have an mmap of the fb, and there's no good
way (that I know of) to prevent it from touching the device otherwise.
This fixes some nasty races between runpm and plymouth on some systems,
which result in the GPU getting very upset and hanging the boot.

SiS 761 chipset does not support AGP cards but has AGP capability (for
the onboard video). At least PC Chips A31G board using this chipset has
an AGP-like AGPro slot that's wired to the PCI bus. Enabling AGP will
fail (GPU lockup and software fbcon, X11 hangs).
Add support for matching just the host bridge in nvkm_device_agp_quirks
and add entry for SiS 761 with mode 0 (AGP disabled).

"After switching to version 4.1.6, our parallelized and distributed
workflows now fail consistently with errors of the form:
T34: ./regex.c:39:22: error: config.h: No such file or directory
From our 'git bisect' testing, the following commit appears to be the
possible cause of the behavior we've been seeing: commit 766c4cbfacd8"
Al Viro says:
"What happens is that 766c4cbfacd8 got the things subtly wrong.
We used to treat d_is_negative() after lookup_fast() as "fall with
ENOENT". That was wrong - checking ->d_flags outside of ->d_seq
protection is unreliable and failing with hard error on what should've
fallen back to non-RCU pathname resolution is a bug.
Unfortunately, we'd pulled the test too far up and ran afoul of
another kind of staleness. The dentry might have been absolutely
stable from the RCU point of view (and we might be on UP, etc), but
stale from the remote fs point of view. If ->d_revalidate() returns
"it's actually stale", dentry gets thrown away and the original code
wouldn't even have looked at its ->d_flags.
What we need is to check ->d_flags where 766c4cbfacd8 does (prior to
->d_seq validation) but only use the result in cases where we do not
discard this dentry outright"

Commit 76c44f6d80 introduced the possibly for "Overflow" to be reported
by the snapshot device's status. Older userspace (e.g. lvm2) does not
handle the "Overflow" status response.
Fix this incompatibility by requiring newer userspace code, that can
cope with "Overflow", request the persistent store with overflow support
by using "PO" (Persistent with Overflow) for the snapshot store type.

Recent Linux clients have started to send GETLAYOUT requests with
minlength less than blocksize.
Servers aren't really allowed to impose this kind of restriction on
layouts; see RFC 5661 section 18.43.3 for details.
This has been observed to cause indefinite hangs on fsx runs on some
clients.

When a device group is detached from its domain, the iommu
core code calls into the iommu driver to detach each device
individually.
Before this functionality went into the iommu core code, it
was implemented in the drivers, also in the AMD IOMMU
driver as the device alias handling code.
This code is still present, as there might be aliases that
don't exist as real PCI devices (and are therefore invisible
to the iommu core code).
Unfortunatly it might happen now, that a device is unbound
multiple times from its domain, first by the alias handling
code and then by the iommu core code (or vice verca).
This ends up in the do_detach function which dereferences
the dev_data->domain pointer. When the device is already
detached, this pointer is NULL and we get a kernel oops.
Removing the alias code completly is not an option, as that
would also remove the code which handles invisible aliases.
The code could be simplified, but this is too big of a
change outside the merge window.
For now, just check the dev_data->domain pointer in
do_detach and bail out if it is NULL.

AMD IOMMU driver makes use of IOMMU PCI devices, so prevent binding other
PCI drivers to IOMMU PCI devices.
This fixes a bug reported by Boris that system suspend/resume gets broken
on AMD platforms. For more information, please refer to:

As we're about to remove the of_node field from the irqdomain
structure, introduce an accessor for it. Subsequent patches
will take care of the actual repainting.

A recent cleanup removed the 'irq' parameter from many functions, but
left the documentation for this in place for at least one function.
This removes it.

A cleanup of the omap gpio driver introduced a use of the
handle_bad_irq() function in a device driver that can be
a loadable module.
This broke the ARM allmodconfig build:
ERROR: "handle_bad_irq" [drivers/gpio/gpio-omap.ko] undefined!
This patch exports the handle_bad_irq symbol in order to
allow the use in modules.
