The USB patches have been acked by Greg K-H.

ARM: 7304/1: ioremap: fix boundary check when reusing static mapping
Since commit
576d2f2525612ecb5af029a76f21f22a3b82563d "ARM: add
generic ioremap optimization by reusing static mappings" ioremap()
is trying to reuse existing static mapping when possible.
The condition checking boundaries of the requested and existing
mappings didn't take in-page offset into consideration though,
which lead to obscure and hard to debug problems when requested
mapping crossed end of the static one.

x86/microcode_amd: Add support for CPU family specific container files
We've decided to provide CPU family specific container files
(starting with CPU family 15h). E.g. for family 15h we have to
load microcode_amd_fam15h.bin instead of microcode_amd.bin
Rationale is that starting with family 15h patch size is larger
than 2KB which was hard coded as maximum patch size in various
microcode loaders (not just Linux).
Container files which include patches larger than 2KB cause
different kinds of trouble with such old patch loaders. Thus we
have to ensure that the default container file provides only
patches with size less than 2KB.

Note that this wouldn't happen on a production system, as you wouldn't

The debugging info printed in these messages is no longer very useful

eCryptfs: Check inode changes in setattr
Most filesystems call inode_change_ok() very early in ->setattr(), but
eCryptfs didn't call it at all. It allowed the lower filesystem to make
the call in its ->setattr() function. Then, eCryptfs would copy the
appropriate inode attributes from the lower inode to the eCryptfs inode.
This patch changes that and actually calls inode_change_ok() on the
eCryptfs inode, fairly early in ecryptfs_setattr(). Ideally, the call
would happen earlier in ecryptfs_setattr(), but there are some possible
inode initialization steps that must happen first.
Since the call was already being made on the lower inode, the change in
functionality should be minimal, except for the case of a file extending
truncate call. In that case, inode_newsize_ok() was never being
called on the eCryptfs inode. Rather than inode_newsize_ok() catching
maximum file size errors early on, eCryptfs would encrypt zeroed pages
and write them to the lower filesystem until the lower filesystem's
write path caught the error in generic_write_checks(). This patch
introduces a new function, called ecryptfs_inode_newsize_ok(), which
checks if the new lower file size is within the appropriate limits when
the truncate operation will be growing the lower file.
In summary this change prevents eCryptfs truncate operations (and the
resulting page encryptions), which would exceed the lower filesystem
limits or FSIZE rlimits, from ever starting.

eCryptfs: Make truncate path killable
ecryptfs_write() handles the truncation of eCryptfs inodes. It grabs a
page, zeroes out the appropriate portions, and then encrypts the page
before writing it to the lower filesystem. It was unkillable and due to
the lack of sparse file support could result in tying up a large portion
of system resources, while encrypting pages of zeros, with no way for
the truncate operation to be stopped from userspace.
This patch adds the ability for ecryptfs_write() to detect a pending
fatal signal and return as gracefully as possible. The intent is to
leave the lower file in a useable state, while still allowing a user to
break out of the encryption loop. If a pending fatal signal is detected,
the eCryptfs inode size is updated to reflect the modified inode size
and then -EINTR is returned.

drm/ttm: fix two regressions since move_notify changes
Both changes in
dc97b3409a790d2a21aac6e5cdb99558b5944119 cause serious
regressions in the nouveau driver.
move_notify() was originally able to presume that bo->mem is the old node,
and new_mem is the new node. The above commit moves the call to
move_notify() to after move() has been done, which means that now, sometimes,
new_mem isn't the new node at all, bo->mem is, and new_mem points at a
stale, possibly-just-been-killed-by-move node.
This is clearly not a good situation. This patch reverts this change, and
replaces it with a cleanup in the move() failure path instead.
The second issue is that the call to move_notify() from cleanup_memtype_use()
causes the TTM ghost objects to get passed into the driver. This is clearly
bad as the driver knows nothing about these "fake" TTM BOs, and ends up
accessing uninitialised memory.
I worked around this in nouveau's move_notify() hook by ensuring the BO
destructor was nouveau's. I don't particularly like this solution, and
would rather TTM never pass the driver these objects. However, I don't
clearly understand the reason why we're calling move_notify() here anyway
and am happy to work around the problem in nouveau instead of breaking the
behaviour expected by other drivers.

ARM: 7299/1: ftrace: clear zero bit in reported IPs for Thumb-2
The dynamic ftrace ops startup test currently fails on Thumb-2 kernels:
Testing tracer function: PASSED
Testing dynamic ftrace: PASSED
Testing dynamic ftrace ops #1: (0 0 0 0 0) FAILED!
This is because while the addresses in the mcount records do not have
the zero bit set, the IP reported by the mcount call does have it set
(because it is copied from the LR). This mismatch causes the ops
filtering in ftrace_ops_list_func() to not call the relevant tracers.
Fix this by clearing the zero bit before adjusting the LR for the mcount
instruction size. Also, combine the mov+sub into a single sub
instruction.

ARM: 7298/1: realview: fix mapping of MPCore private memory region
Since commit
0536bdf33faf (ARM: move iotable mappings within
the vmalloc region), the RealView PB11MP cannot boot anymore.
This is caused by the way the mappings are described on this
platform (define replaced by hex values for clarity):
{ /* GIC CPU interface mapping */
.virtual = IO_ADDRESS(0x1F000100),
.pfn = __phys_to_pfn(0x1F000100),
.length = SZ_4K,
.type = MT_DEVICE,
}, { /* GIC distributor mapping */
.virtual = IO_ADDRESS(0x1F001000),
.pfn = __phys_to_pfn(0x1F001000),
.length = SZ_4K,
.type = MT_DEVICE,
}
The first mapping ends up reserving two pages, and clashes with
the second one, which triggers a BUG_ON in vm_area_add_early().
In order to solve this problem, treat the MPCore private memory
region (containing the SCU, the GIC and the TWD) as a single region,
as described in the TRM:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/CACGDJJC.html
The EB11MP is converted the same way, even if it manages to avoid
the problem.
Tested on both PB11MP and EB11MP.

rds_sock_info() triggers locking warnings because we try to perform a

There is no reason for rds_sock_lock to be a hardware IRQ disabling
