48d480b0bde794781fcae9501fb043c1bac0e523 [[MIPS] Malta: Fix off by one bug in interrupt
handler.] did not take in account that irq_ffs() will also return 0 if for some reason
the set of pending interrupts happens to be empty.
This is trivial to trigger with a RM5261 CPU module running a 64-bit kernel and results
in something like the following:

Kernel panic - not syncing: Fatal exception in interrupt
Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

YAMON requires and enforces the RTC Data Mode (Register B, DM bit) to
binary, that is the bit is set every time the board goes through the
firmware bootstrap sequence. Likewise its calendar manipulation commands
interpret or set the RTC registers unconditionally as binary, never
actually checking what the value of the DM bit is, under the (correct)
assumption that it has been previously set, to indicate the binary mode.
A change to Linux a while ago however introduced a platform-specific
tweak that clears that bit and therefore forces the data mode to BCD.
This causes clock corruption and misinterpretation that has to be fixed up
by user-mode tools in system startup scripts as the initial clock is often
incorrect according to the BCD interpretation forced.
This change removes the hack; a comment included refers to alarm code,
but even if it was broken at one point by requiring the BCD mode, it
should have been trivially corrected and even if not, given how rarely the
alarm feature is used, that was not really a reasonable justification to
break the system clock that is indeed used by virtually everything. And
either way the alarm code has been since fixed anyway.

For CIUv1 controllers, we were relying on all calls to the irq_chip
functions to be done from the CPU that received the irq, and that they
would all be done from interrupt contest. These assumptions do not
hold for threaded handlers.
We make all the masking actually mask the irq source, and use real
raw_spin_locks instead of manually twiddling the Status[IE] bit.

Commit 91f68c89d8f3 ("block: fix infinite loop in __getblk_slow")
is not good: a successful call to grow_buffers() cannot guarantee
that the page won't be reclaimed before the immediate next call to
__find_get_block(), which is why there was always a loop there.
Yesterday I got "EXT4-fs error (device loop0): __ext4_get_inode_loc:3595:
inode #19278: block 664: comm cc1: unable to read itable block" on console,
which pointed to this commit.
I've been trying to bisect for weeks, why kbuild-on-ext4-on-loop-on-tmpfs
sometimes fails from a missing header file, under memory pressure on
ppc G5. I've never seen this on x86, and I've never seen it on 3.5-rc7
itself, despite that commit being in there: bisection pointed to an
irrelevant pinctrl merge, but hard to tell when failure takes between
18 minutes and 38 hours (but so far it's happened quicker on 3.6-rc2).
(I've since found such __ext4_get_inode_loc errors in /var/log/messages
from previous weeks: why the message never appeared on console until
yesterday morning is a mystery for another day.)
Revert 91f68c89d8f3, restoring __getblk_slow() to how it was (plus
a checkpatch nitfix). Simplify the interface between grow_buffers()
and grow_dev_page(), and avoid the infinite loop beyond end of device
by instead checking init_page_buffers()'s end_block there (I presume
that's more efficient than a repeated call to blkdev_max_block()),
returning -ENXIO to __getblk_slow() in that case.
And remove akpm's ten-year-old "__getblk() cannot fail ... weird"
comment, but that is worrying: are all users of __getblk() really
now prepared for a NULL bh beyond end of device, or will some oops??

This issue was recently observed on an AMD C-50 CPU where a patch of
maximum size was applied.
Commit be62adb49294 ("x86, microcode, AMD: Simplify ucode verification")
added current_size in get_matching_microcode(). This is calculated as
size of the ucode patch + 8 (ie. size of the header). Later this is
compared against the maximum possible ucode patch size for a CPU family.
And of course this fails if the patch has already maximum size.

Pull drm fixes from Dave Airlie:
"Intel: edid fixes, power consumption fix, s/r fix, haswell fix
Radeon: BIOS loading fixes for UEFI and Thunderbolt machines, better
MSAA validation, lockup timeout fixes, modesetting fixes
One udl dpms fix, one vmwgfx fix, a couple of trivial core changes.
There is an export added to ACPI as part of the radeon bios fixes.
I've also included the fbcon flashing cursor vs deinit race fix, that
seems the simplest place to start"
Trivial conflict in drivers/video/console/fbcon.c due to me having
already applied the fbcon flashing cursor vs deinit race fix, and Dave
had added a comment in there too.
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (22 commits)
fbcon: fix race condition between console lock and cursor timer (v1.1)
drm: Add missing static storage class specifiers in drm_proc.c file
drm/udl: dpms off the crtc when disabled.
drm: Remove two unused fields from struct drm_display_mode
drm: stop vmgfx driver explosion
drm/radeon/ss: use num_crtc rather than hardcoded 6
Revert "drm/radeon: fix bo creation retry path"

Pull SCSI target fixes from Nicholas Bellinger:
"The executive summary includes:
- Post-merge review comments for tcm_vhost (MST + nab)
- Avoid debugging overhead when not debugging for tcm-fc(FCoE) (MDR)
- Fix NULL pointer dereference bug on alloc_page failulre (Yi Zou)
- Fix REPORT_LUNs regression bug with pSCSI export (AlexE + nab)
- Fix regression bug with handling of zero-length data CDBs (nab)
- Fix vhost_scsi_target structure alignment (MST)
Thanks again to everyone who contributed a bugfix patch, gave review
feedback on tcm_vhost code, and/or reported a bug during their own
testing over the last weeks.
There is one other outstanding bug reported by Roland recently related
to SCSI transfer length overflow handling, for which the current
proposed bugfix has been left in queue pending further testing with
other non iscsi-target based fabric drivers.
As the patch is verified with loopback (local SGL memory from SCSI
LLD) + tcm_qla2xxx (TCM allocated SGL memory mapped to PCI HW) fabric
ports, it will be included into the next 3.6-rc-fixes PULL request."
* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
target: Remove unused se_cmd.cmd_spdtl
tcm_fc: rcu_deref outside rcu lock/unlock section
tcm_vhost: Fix vhost_scsi_target structure alignment
target: Fix regression bug with handling of zero-length data CDBs
target/pscsi: Fix bug with REPORT_LUNs handling for SCSI passthrough
tcm_vhost: Change vhost_scsi_target->vhost_wwpn to char *
target: fix NULL pointer dereference bug alloc_page() fails to get memory
tcm_fc: Avoid debug overhead when not debugging
tcm_vhost: Post-merge review changes requested by MST
tcm_vhost: Fix incorrect IS_ERR() usage in vhost_scsi_map_iov_to_sgl

git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull ceph fixes from Sage Weil:
"Jim's fix closes a narrow race introduced with the msgr changes. One
fix resolves problems with debugfs initialization that Yan found when
multiple client instances are created (e.g., two clusters mounted, or
rbd + cephfs), another one fixes problems with mounting a nonexistent
server subdirectory, and the last one fixes a divide by zero error
from unsanitized ioctl input that Dan Carpenter found."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
ceph: avoid divide by zero in __validate_layout()
libceph: avoid truncation due to racing banners
ceph: tolerate (and warn on) extraneous dentry from mds
libceph: delay debugfs initialization until we learn global_id
