I'm not sure what I was on when I wrote this, but when iterating over
the hardware watchpoint array (hbp_watch_array), our index is off by
ARM_MAX_BRP, so we walk off the end of our thread_struct...
... except, a dodgy condition in the loop means that it never executes
at all (bp cannot be NULL).
This patch fixes the code so that we remove the bp check and use the
correct index for accessing the watchpoint structures.

The DM crypt target accesses memory beyond allocated space resulting in
a crash on 32 bit x86 systems.
This bug is very old (it dates back to 2.6.25 commit 3a7f6c990a "dm
crypt: use async crypto"). However, this bug was masked by the fact
that kmalloc rounds the size up to the next power of two. This bug
wasn't exposed until 3.17-rc1 commit 298a9fa08a ("dm crypt: use per-bio
data"). By switching to using per-bio data there was no longer any
padding beyond the end of a dm-crypt allocated memory block.
To minimize allocation overhead dm-crypt puts several structures into one
block allocated with kmalloc. The block holds struct ablkcipher_request,
cipher-specific scratch pad (crypto_ablkcipher_reqsize(any_tfm(cc))),
struct dm_crypt_request and an initialization vector.
The variable dmreq_start is set to offset of struct dm_crypt_request
within this memory block. dm-crypt allocates the block with this size:
cc->dmreq_start + sizeof(struct dm_crypt_request) + cc->iv_size.
When accessing the initialization vector, dm-crypt uses the function
iv_of_dmreq, which performs this calculation: ALIGN((unsigned long)(dmreq
+ 1), crypto_ablkcipher_alignmask(any_tfm(cc)) + 1).
dm-crypt allocated "cc->iv_size" bytes beyond the end of dm_crypt_request
structure. However, when dm-crypt accesses the initialization vector, it
takes a pointer to the end of dm_crypt_request, aligns it, and then uses
it as the initialization vector. If the end of dm_crypt_request is not
aligned on a crypto_ablkcipher_alignmask(any_tfm(cc)) boundary the
alignment causes the initialization vector to point beyond the allocated
space.
Fix this bug by calculating the variable iv_size_padding and adding it
to the allocated size.
Also correct the alignment of dm_crypt_request. struct dm_crypt_request
is specific to dm-crypt (it isn't used by the crypto subsystem at all),
so it is aligned on __alignof__(struct dm_crypt_request).
Also align per_bio_data_size on ARCH_KMALLOC_MINALIGN, so that it is
aligned as if the block was allocated with kmalloc.

Commit 43fef47f94 (mfd: twl4030-power: Add a configuration to turn
off oscillator during off-idle) added support for configuring the PMIC
to cut off resources during deeper idle states to save power.
This however caused regression for n900 display power that needed the
PMIC configuration to be disabled with commit d937678ab6 (ARM: dts:
Revert enabling of twl configuration for n900).
Turns out the root cause of the problem is that we must use
TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling
regulators that may have been enabled before the init function
for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the
regulator framework control the regulators like it should. Here we
need to only configure the sys_clken and sys_off_mode triggers for
the regulators that cannot be done by the regulator framework as
it's not running at that point.
This allows us to enable the PMIC configuration for n900.

The nocb callbacks generated before the nocb kthreads are spawned are
enqueued in the nocb queue for later processing. Commit fbce7497ee ("rcu:
Parallelize and economize NOCB kthread wakeups") introduced nocb leader kthreads
which checked the nocb_leader_wake flag to see if there were any such pending
callbacks. A case was reported in which newly spawned leader kthreads were not
processing the pending callbacks as this flag was not set, which led to a boot
hang.
The following commit ensures that the newly spawned nocb kthreads process the
pending callbacks by allowing the kthreads to run immediately after spawning
instead of waiting. This is done by inverting the logic of nocb_leader_wake
tests to nocb_leader_sleep which allows us to use the default initialization of
this flag to 0 to let the kthreads run.

I've received a bug report from a user that the touchpad control part
of the ideapad-laptop ACPI interface does work for him on his

Since it did not work for me when I had a "Lenovo Yoga 2 11" in my own
hands (loaned from a friend). It seems that this is a bit of hit and miss.
Since the result of having a false positive here is worse, then the minor
annoyance of a false touchpad disabled messages being shown after suspend /
resume on models (or is it firmware versions?) where the interface does not
work, simply revert the patch.

The __init annotations for the DMI callback functions are wrong as this
code can be called even after the module has been initialized, e.g. like
this:
# echo 1 > /sys/bus/pci/devices/0000:00:02.0/remove
# modprobe i915
# echo 1 > /sys/bus/pci/rescan
The first command will remove the PCI device from the kernel's device
list so the second command won't see it right away. But as it registers
a PCI driver it'll see it on the third command. If the system happens to
match one of the DMI table entries we'll try to call a function in long
released memory and generate an Oops, at best.
Fix this by removing the bogus annotation.
Modpost should have caught that one but it ignores section reference
mismatches from the .rodata section. :/

Since this is a platform driver and can be probed at any time we can't
annotate funtions in the probe path as __init, the code can't safely be
discarded at the end of kernel init.

On larger systems intel_pstate currently spams the boot up
log with its "Intel pstate controlling ..." message for each CPU.
It's the only subsystem that prints a message for each
CPU.
Turn the message into a pr_debug.

After commit f282ac19d8 we use different transactions for
preallocation and i_disksize update which result in complain from fsck
after power-failure. spotted by generic/019. IMHO this is regression
because fs becomes inconsistent, even more 'e2fsck -p' will no longer
works (which drives admins go crazy) Same transaction requirement
applies ctime,mtime updates

If we assign a Radeon device to a virtual machine, we can no longer
assume a fixed hardware topology, like the GPU having a parent device.
This patch simply adds a few pci_is_root_bus() tests to avoid passing
a NULL pointer to PCI access functions, allowing the radeon driver to
work in a QEMU 440FX machine with an assigned HD8570 on the emulated
PCI root bus.

This is a bit bigger hammer then I would like to use for this, but for now
it will have to make do. I'm working on getting my hands on one of these so
that I can try to get streams to work (with a quirk flag if necessary) and
then we can re-enable them.
For now this at least makes uas capable disk enclosures work again by forcing
fallback to the usb-storage driver.

Make sure to verify the number of ports requested by subdriver to avoid
writing beyond the end of fixed-size array in interface data.
The current usb-serial implementation is limited to eight ports per
interface but failed to verify that the number of ports requested by a
subdriver (which could have been determined from device descriptors) did
not exceed this limit.
