The address check in acpi_hw_get_access_bit_width() should be byte width
based, not bit width based. This patch fixes this mistake.
For those who want to review acpi_hw_access_bit_width(), here is the
concerns and the design details of the function:
It is supposed that the GAS Address field should be aligned to the byte
width indicated by the GAS AccessSize field. Similarly, for the old non
GAS register, it is supposed that its Address should be aligned to its
Length.
For the "AccessSize = 0 (meaning ANY)" case, we try to return the maximum
instruction width (64 for MMIO or 32 for PIO) or the user expected access
bit width (64 for acpi_read()/acpi_write() or 32 for acpi_hw_read()/
acpi_hw_write()) and it is supposed that the GAS Address field should
always be aligned to the maximum expected access bit width (otherwise it
can't be accessed using ANY access bit width).
The problem is in acpi_tb_init_generic_address(), where the non GAS
register's Length is converted into the GAS BitWidth field, its Address is
converted into the GAS Address field, and the GAS AccessSize field is left
0 but most of the registers actually cannot be accessed using "ANY"
accesses.
As a conclusion, when AccessSize = 0 (ANY), the Address should either be
aligned to the BitWidth (wrong conversion) or aligned to 32 for PIO or 64
for MMIO (real GAS). Since currently, max_bit_width is 32, then:
1. BitWidth for the wrong conversion is 8,16,32; and
2. The Address of the real GAS should always be aligned to 8,16,32.
The address alignment check to exclude false matched real GAS is not
necessary. Thus this patch fixes the issue by removing the address
alignment check.
On the other hand, we in fact could use a simpler check of
"reg->bit_width < max_bit_width" to exclude the "BitWidth=64 PIO" case that
may be issued from acpi_read()/acpi_write() in the future.

In commit 86d3473224b0 some of the checking for a valid timeval
was subtley changed which caused -EINVAL to be returned whenever
the timeval was null.
However, it is possible to set the timezone data while specifying
a NULL timeval, which is usually done to handle systems where the
RTC keeps local time instead of UTC. Thus the patch causes such
systems to have the time incorrectly set.
This patch addresses the issue by handling the error conditionals
in the same way as was done previously.

There are several issues in fscache revalidation code.
- In ceph_revalidate_work(), fscache_invalidate() is called when
fscache_check_consistency() return 0. This is complete wrong
because 0 means cache is valid.
- Handle_cap_grant() calls ceph_queue_revalidate() if client
already has CAP_FILE_CACHE. This code is confusing. Client
should revalidate the cache each time it got CAP_FILE_CACHE
anew.
- In Handle_cap_grant(), fscache_invalidate() is called if MDS
revokes CAP_FILE_CACHE. This is inconsistency with the case
that inode get evicted. In the later case, the cache is not
discarded. Client may use the cache when inode is reloaded.
This patch moves the fscache revalidation into ceph_get_caps().
Client revalidates the cache after it gets CAP_FILE_CACHE.
i_rdcache_gen should keep constance while CAP_FILE_CACHE is
used. If i_fscache_gen is not equal to i_rdcache_gen, client
needs to check cache's consistency.

Since the introduction of (struct_mutex) lockless GEM bo freeing, there
are a pair of driver vfuncs for freeing the GEM bo, of which the driver
may choose to only implement driver->gem_object_free_unlocked (and so
avoid taking the struct_mutex along the free path). However, the CMA GEM
helpers were still calling driver->gem_free_object directly, now NULL,
and promptly dying on the fancy new lockless drivers. Oops.
Robert Foss bisected this to b82caafcf2303 (drm/vc4: Use lockless gem BO
free callback) on his vc4 device, but that just serves as an enabler for
9f0ba539d13ae (drm/gem: support BO freeing without dev->struct_mutex).

After commit 027b3f8ba9277410c3191d72d1ed2c6146d8a668 ("drm/modes: stop
handling framebuffer special") extra fb refs are left around when doing
atomic modesetting.
The problem is that the new drm_property_change_valid_get() does not
return anything in the '**ref' parameter, which causes
drm_property_change_valid_put() to do nothing.
For some reason this doesn't cause problems with legacy API.
Also, previously the code only set the 'ref' variable for fbs, with this
patch the 'ref' is set for all objects.

When setting mode via MODE_ID property,
drm_atomic_set_mode_prop_for_crtc() does not call
drm_mode_set_crtcinfo() which possibly causes:
"[drm:drm_calc_timestamping_constants [drm]] *ERROR* crtc 32: Can't
calculate constants, dotclock = 0!"
Whether the error is seen depends on the previous data in state->mode,
as state->mode is not cleared when setting new mode.
This patch adds drm_mode_set_crtcinfo() call to
drm_mode_convert_umode(), which is called in both legacy and atomic
paths. This should be fine as there's no reason to call
drm_mode_convert_umode() without also setting the crtc related fields.
drm_mode_set_crtcinfo() is removed from the legacy drm_mode_setcrtc() as
that is no longer needed.

If we do not provide the PVR for POWER8NVL, a guest on this system
currently ends up in PowerISA 2.06 compatibility mode on KVM, since QEMU
does not provide a generic PowerISA 2.07 mode yet. So some new
instructions from POWER8 (like "mtvsrd") get disabled for the guest,
resulting in crashes when using code compiled explicitly for
POWER8 (e.g. with the "-mcpu=power8" option of GCC).

When we converted the asm routines to C functions, we missed updating
HPTE_R_R based on _PAGE_ACCESSED. ASM code used to copy over the lower
bits from pte via.
andi. r3,r30,0x1fe /* Get basic set of flags */
We also update the code such that we won't update the Change bit ('C'
bit) always. This was added by commit c5cf0e30bf3d8 ("powerpc: Fix
buglet with MMU hash management").
With hash64, we need to make sure that hardware doesn't do a pte update
directly. This is because we do end up with entries in TLB with no hash
page table entry. This happens because when we find a hash bucket full,
we "evict" a more/less random entry from it. When we do that we don't
invalidate the TLB (hpte_remove) because we assume the old translation
is still technically "valid". For more info look at commit
0608d692463("powerpc/mm: Always invalidate tlb on hpte invalidate and
update").
Thus it's critical that valid hash PTEs always have reference bit set
and writeable ones have change bit set. We do this by hashing a
non-dirty linux PTE as read-only and always setting _PAGE_ACCESSED (and
thus R) when hashing anything else in. Any attempt by Linux at clearing
those bits also removes the corresponding hash entry.
Commit 5cf0e30bf3d8 did that for 'C' bit by enabling 'C' bit always.
We don't really need to do that because we never map a RW pte entry
without setting 'C' bit. On READ fault on a RW pte entry, we still map
it READ only, hence a store update in the page will still cause a hash
pte fault.
This patch reverts the part of commit c5cf0e30bf3d8 ("[PATCH] powerpc:
Fix buglet with MMU hash management") and retain the updatepp part.
- If we hit the updatepp path on native, the old code without that
commit, would fail to set C bcause native_hpte_updatepp()
was implemented to filter the same bits as H_PROTECT and not let C
through thus we would "upgrade" a RO HPTE to RW without setting C
thus causing the bug. So the real fix in that commit was the change
to native_hpte_updatepp

We still need to call btrfs_end_transaction if we call btrfs_abort_transaction,
otherwise we hang and make me super grumpy. Thanks,

As per the documentation in drm_crtc.h, atomic_commit should return
-EBUSY if an asynchronous update is requested and there is an earlier
update pending.

The async page flip path was missing drm_crtc_vblank_get/put
completely. The sync flip path was missing a vblank put, so async
flips only reported proper pageflip completion events by chance,
and vblank irq's never turned off after a first vsync'ed page flip
until system reboot.
Tested against Raspian kernel 4.4.8 tree on RPi 2B.

get_vblank_counter hooked up to drm_vblank_count() which alway was
non-sensical but didn't hurt in the past. Since Linux 4.4 it
triggers a WARN_ON_ONCE in drm_update_vblank_count on first vblank
irq disable, so fix it by hooking to drm_vblank_no_hw_counter().

To detect link status up/down for connections where autonegotiation is
explicitly disabled, we don't get an irq but need to poll the status
register for link up/down detection.
This patch adds a workqueue to poll for link status.

In function virtnet_open() and virtnet_probe(), func try_fill_recv() may
be executed at the same time. VQ in virtqueue_add() has not been protected
well and BUG_ON will be triggered when virito_net.ko being removed.

bnx2x_init_bp() allocates memory with bnx2x_alloc_mem_bp() so if we
fail later in bnx2x_init_one() we need to free this memory
with bnx2x_free_mem_bp() to avoid leakages. E.g. I'm observing memory
leaks reported by kmemleak when a failure (unrelated) happens in
bnx2x_vfpf_acquire().

The Kconfig options I added to work around broken compilation ended
up screwing up things more, as I used the wrong symbol to control
compilation of the file, resulting in IPv6 fou support to never be built
into the kernel.
Changing CONFIG_NET_FOU_IPV6_TUNNELS to CONFIG_IPV6_FOU fixes that
problem, I had renamed the symbol in one location but not the other,
and as the file is never being used by other kernel code, this did not
lead to a build failure that I would have caught.
After that fix, another issue with the same patch becomes obvious, as we
'select INET6_TUNNEL', which is related to IPV6_TUNNEL, but not the same,
and this can still cause the original build failure when IPV6_TUNNEL is
not built-in but IPV6_FOU is. The fix is equally trivial, we just need
to select the right symbol.
I have successfully build 350 randconfig kernels with this patch
and verified that the driver is now being built.

{push,pop}_mpls() as they the type in the ethernet header.
