According to create_thread(3): "The new thread does not inherit the creating

corruption among cloned threads), current->sas_ss_size is set to 0 for cloned
processes sharing VM with their parent. Don't use the (nonexistent) alternate

The commit d0a0ce3e77 ("thermal: exynos: Add

value at TMU configuration setting.
This field is not present on Exynos4210 and Exynos5 SoCs. However on Exynos4412
SoC it is required to set this field after reset because without it TMU shows
maximal available temperature, which causes immediate platform shutdown.

Since Exynos4412 was chronologically first, the corresponding name for
TMU registers and default data was renamed.
Additionally, new SOC_ARCH_EXYNOS4412 type has been defined.
Moreover, the SOC_ARCH_EXYNOS name has been changed to SOC_ARCH_EXYNOS5250.

The commit 4de0bdaa96
("thermal: exynos: Add support for instance based register/unregister")
broke check for presence of therm_dev at global thermal zone in
exynos_report_trigger().
The resulting wrong test prevents thermal_zone_device_update() call, which
calls handlers for situation when trip points are passed.
Such behavior prevents thermal driver from proper reaction (when TMU interrupt
is raised) in a situation when overheating is detected at TMU hardware.
It turns out, that after exynos thermal subsystem redesign (at v3.12) this
check is not needed, since it is not possible to register thermal zone
without valid thermal device.

If EM Transmit bit is busy during init ata_msleep() is called. It is
wrong - msleep() should be used instead of ata_msleep(), because if EM
Transmit bit is busy for one port, it will be busy for all other ports
too, so using ata_msleep() causes wasting tries for another ports.
The most common scenario looks like that now
(six ports try to transmit a LED meaasege):
- port #0 tries for the 1st time and succeeds
- ports #1-5 try for the 1st time and sleeps
- port #1 tries for the 2nd time and succeeds
- ports #2-5 try for the 2nd time and sleeps
- port #2 tries for the 3rd time and succeeds
- ports #3-5 try for the 3rd time and sleeps
- port #3 tries for the 4th time and succeeds
- ports #4-5 try for the 4th time and sleeps
- port #4 tries for the 5th time and succeeds
- port #5 tries for the 5th time and sleeps
At this moment port #5 wasted all its five tries and failed to
initialize. Because there are only 5 (EM_MAX_RETRY) tries available
usually only five ports succeed to initialize. The sixth port and next
ones usually will fail.
If msleep() is used instead of ata_msleep() the first port succeeds to
initialize in the first try and next ones usually succeed to
initialize in the second try.

We use jump label to enable pv-spinlock. With the changes in (442e0973e9
Merge branch 'x86/jumplabel'), the jump label behaviour has changed
that would result in eventual hang of the VM since we would end up in a
situation where slow path locks would halt the vcpus but we will not be
able to wakeup the vcpu by lock releaser using unlock kick.
Similar problem in Xen and more detailed description is available in
a945928ea2 (xen: Do not enable spinlocks before jump_label_init()
has executed)
This patch splits kvm_spinlock_init to separate jump label changes with
pvops patching and also make jump label enabling after jump_label_init().

The pcm_usb_stream plugin requires the mremap explicitly for the read
buffer, as it expands itself once after reading the required size.
But the commit [314e51b9: mm: kill vma flag VM_RESERVED and
mm->reserved_vm counter] converted blindly to a combination of
VM_DONTEXPAND | VM_DONTDUMP like other normal drivers, and this
resulted in the failure of mremap().
For fixing this regression, we need to remove VM_DONTEXPAND for the
read-buffer mmap.

This patch adds missing cfg80211_disconnected event for P2P client
interface upon successful deauthenticate command, deauthenticate
event or disassociate event from FW.

If device is surprise removed, commands sent to FW including
deauthenticate command fail as bus writes fail.
We update our media_connected status to false and inform cfg80211
about disconnection only when command is successful. Since cfg80211
assumes device is still connected, it results into following
WARN_ON during unload:
WARNING: CPU: 0 PID: 18245 at net/wireless/core.c:937
cfg80211_netdev_notifier_call+0x175/0x4d0 [cfg80211]()
Avoid this by emitting cfg80211_disconnected event even if the
deauthenticate command fails.

Functions that walk the ntstatus_to_dos_map[] array could
run off the end. For example, ntstatus_to_dos() loops
while ntstatus_to_dos_map[].ntstatus is not 0. Granted,
this is mostly theoretical, but could be used as a DOS attack
if the error code in the SMB header is bogus.
[Might consider adding to stable, as this patch is low risk - Steve]

In function filename__read_debuglink(), while the ELF file is opend and
mmapped in elf_begin(), but if this file is considered to not be usable
during the following code, we will goto the close(fd) directly. The
elf_end() is skipped. So, the mmaped ELF file cannot be munmapped. The
mmapped areas exist during the life of perf.
This is a memory leak. This patch fixed this bug.

kcore can be used to view the running kernel object code. However,
kcore changes as modules are loaded and unloaded, and when the kernel
decides to modify its own code. Consequently it is useful to create a
copy of kcore at a particular time. Unlike vmlinux, kcore is not unique
for a given build-id. And in addition, the kallsyms and modules files
are also needed. The tool therefore creates a directory:
~/.debug/[kernel.kcore]/<build-id>/<YYYYmmddHHMMSShh>
which contains: kcore, kallsyms and modules.
Note that the copied kcore contains only code sections. See the
kcore_copy() function for how that is determined.
The tool will not make additional copies of kcore if there is already
one with the same modules at the same addresses.
Currently, perf tools will not look for kcore in the cache. That is
addressed in another patch.
