This reverts commit 24a0aa212ee2dbe44360288684478d76a8e20a0a.
It's causing severe userspace breakage. Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.
Please see [1] for example of the userspace breakage this is causing.
In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.
To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

Commit ac61d1955934 (scsi: set correct completion code in
scsi_send_eh_cmnd()) introduced a bug. It changed the stored return
value from a queuecommand call, but it didn't take into account that
the return value was used again later on. This patch fixes the bug by
changing the later usage.
There is a big comment in the middle of scsi_send_eh_cmnd() which
does a good job of explaining how the routine works. But it mentions
a "rtn = FAILURE" value that doesn't exist in the code. This patch
adjusts the code to match the comment (I assume the comment is right
and the code is wrong).
This fixes Bugzilla #88341.

Currently we enable Exynos devices in the multi v7 defconfig, however, when
testing on my ODROID-U3, I noticed that USB was not working. Enabling this
option causes USB to work, which enables networking support as well since the
ODROID-U3 has networking on the USB bus.
[arnd] Support for odroid-u3 was added in 3.10, so it would be nice to
backport this fix at least that far.

Unfortunately, while commit 4a928436 ("audit: correctly record file
names with different path name types") fixed a problem where we were
not recording filenames, it created a new problem by attempting to use
these file names after they had been freed. This patch resolves the
issue by creating a copy of the filename which the audit subsystem
frees after it is done with the string.
At some point it would be nice to resolve this issue with refcounts,
or something similar, instead of having to allocate/copy strings, but
that is almost surely beyond the scope of a -rcX patch so we'll defer
that for later. On the plus side, only audit users should be impacted
by the string copying.

7985090aa020 changed the discard heuristics to give preference to the
WRITE SAME commands that (unlike UNMAP) guarantee deterministic results.
Ming Lei discovered that QEMU SCSI's WRITE SAME implementation
internally relied on limits that were only communicated for the UNMAP
case. And therefore discard commands backed by WRITE SAME would fail.
Tweak the heuristics so we still pick UNMAP in the LBPRZ=0 case and only
prefer the WRITE SAME variants if the device has the LBPRZ flag set.

The Rockchip pinctrl driver was only implementing the "mask" and
"unmask" operations though the hardware actually has two distinct
things: enable/disable and mask/unmask. It was implementing the
"mask" operations as a hardware enable/disable and always leaving all
interrupts unmasked.
I believe that the old system had some downsides, specifically:
- (Untested) if an interrupt went off while interrupts were "masked"
it would be lost. Now it will be kept track of.
- If someone wanted to change an interrupt back into a GPIO (is such a
thing sensible?) by calling irq_disable() it wouldn't actually take
effect. That's because Linux does some extra optimizations when
there's no true "disable" function: it does a lazy mask.
Let's actually implement enable/disable/mask/unmask properly.

The rockchip pinctrl driver was using irq_gc_set_wake() as its
implementation of irq_set_wake() but was totally ignoring everything
that irq_gc_set_wake() did (which is to upkeep gc->wake_active).
Let's fix that by setting gc->wake_active as GPIO_INTEN at suspend
time and restoring GPIO_INTEN at resume time.
NOTE a few quirks when thinking about this patch:
- Rockchip pinctrl hardware supports both "disable/enable" and
"mask/unmask". Right now we only use "disable/enable" and present
those to Linux as "mask/unmask". This should be OK because
enable/disable is optional and Linux will implement it in terms of
mask/unmask. At the moment we always tell hardware all interrupts
are unmasked (the boot default).
- At suspend time Linux tries to call "disable" on all interrupts and
also enables wakeup on all wakeup interrupts. One would think that
since "disable" is implemented as "mask" when "disable" isn't
provided and that since we were ignoring gc->wake_active that
nothing would have woken us up. That's not the case since Linux
"optimizes" things and just leaves interrutps unmasked, assuming it
could mask them later when they go off. That meant that at suspend
time all interrupts were actually being left enabled.
With this patch random non-wakeup interrupts no longer wake the system
up. Wakeup interrupts still wake the system up.

After the commit ef691ff48bc8 (OMAPDSS: DT: Get source endpoint by
matching reg-id) we look for the SDI output using the port number.
However, the SDI driver doesn't set the port number, which causes the
SDI display to not initialize.
Fix this by setting the SDI port number to 1. We use a hardcoded value,
as SDI was used only on OMAP3 and it's always port number 1 there.

"First of all, the most important change is the thermal cpu cooling

cpufreq layer and thermal cpu cooling registration. A take away of
this fix is an improvement in the thermal drivers code. Thermal
drivers that require cpu cooling do not need to check for cpufreq
layer. The requirement now is to propagate the error code, if any,
while registering cpu cooling device. Thanks to Viresh for
implementing the required CPUfreq changes.
Second, a new driver is introduced for int340x processor thermal
device. Given that int340x thermal is disabled by default, and this
processor thermal device is only available on limited platforms, plus
the driver does nothing but exposes some thermal limitation
information for user space to use, thus I think it is safe to include

Commit 2457aec63745 ("mm: non-atomically mark page accessed during page
cache allocation where possible") has added a separate parameter for
specifying gfp mask for radix tree allocations.
Not only this is less than optimal from the API point of view because it
is error prone, it is also buggy currently because
grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if
fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by
AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then
the radix tree allocation wouldn't obey the restriction and might
recurse into filesystem and cause deadlocks. This is the case for most
filesystems unfortunately because only ext4 and gfs2 are using
AOP_FLAG_NOFS.
Let's simply remove radix_gfp_mask parameter because the allocation
context is same for both page cache and for the radix tree. Just make
sure that the radix tree gets only the sane subset of the mask (e.g. do
not pass __GFP_WRITE).
Long term it is more preferable to convert remaining users of
AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this
interface even further.

This patch changes the radeon_kfd_init(), which is used to initialize the
interface between radeon and amdkfd, so the interface will be initialized only
if amdkfd was build, either as module or inside the kernel image.
In the modules case, the symbol_request() will be used (same as old code). In
the in-image compilation case, a direct call to kgd2kfd_init() will be done.
For other cases, radeon_kfd_init() will just return false.
This patch is necessary because in case of the following specific
configuration: kernel 32-bit, no modules support, random kernel base and no
hibernation, the symbol_request() doesn't work as expected - it doesn't return
NULL if the symbol doesn't exists - which makes the kernel panic.

being over 80 characters are present in the original files too and this
patch was made in the same style (no line break).
Just adding a new id and changing the required places should make the
new device work without any issues according to the bug report in the
following url.
This patch was made according to and fixes:

virtio 1.0 only requires used address to be 4 byte aligned,
vhost required 8 bytes (size of vring_used_elem).
Fix up vhost to match that.
Additionally, while vhost correctly requires 8 byte
alignment for log, it's unconnected to used ring:
it's a consequence that log has u64 entries.
Tweak code to make that clearer.

Host needs to know vring element alignment requirements:
simply doing alignof on structures doesn't work reliably: on some
platforms gcc has alignof(uint32_t) == 2.
Add macros for alignment as specified in virtio 1.0 cs01,
export them to userspace as well.

If the probe of an fb driver has been deferred due to missing
dependencies, and the probe is later ran when a module is loaded, the
fbdev framework will try to find a logo to use.
However, the logos are __initdata, and have already been freed. This
causes sometimes page faults, if the logo memory is not mapped,
sometimes other random crashes as the logo data is invalid, and
sometimes nothing, if the fbdev decides to reject the logo (e.g. the
random value depicting the logo's height is too big).
This patch adds a late_initcall function to mark the logos as freed. In
reality the logos are freed later, and fbdev probe may be ran between
this late_initcall and the freeing of the logos. In that case we will
miss drawing the logo, even if it would be possible.

This reverts commit 7c5c92ed56d932b2c19c3f8aea86369509407d33.
Although this did fix the bug it was aimed at, it also broke secondary
startup on platforms that use give/take_timebase(). Unfortunately we
didn't detect that while it was in next.

In LE kernel, we currently have a hack for kexec that resets the exception
endian before starting a new kernel as the kernel that is loaded could be a
big endian or a little endian kernel. In kdump case, resetting exception
endian fails when one or more cpus is disabled. But we can ignore the failure
and still go ahead, as in most cases crashkernel will be of same endianess
as primary kernel and reseting endianess is not even needed in those cases.
This patch adds a new inline function to say if this is kdump path. This
function is used at places where such a check is needed.

Commit 0e5bdb3f9fa5 (clk: rockchip: switch to using the new cpuclk type
for armclk) didn't take into account that the divider used on rk3288
are of the (n+1) type.
The rk3066 and rk3188 socs use more complex divider types making it
necessary for the list-elements to be the real register-values to write.
Therefore reduce divider values in the table accordingly so that they
really are the values that should be written to the registers and match
the dividers actually specified for the rk3288.

The bit locations indicating the locking status of the plls on rk3066 are
shifted by one to the right when compared to the rk3188, bits [7:4] instead
of [8:5] on the rk3188, thus indicating the locking state of the wrong pll
or a completely different information in case of the gpll.
The recently introduced pll init code exposed that problem on some rk3066
boards when it tried to bring the boot-pll value in line with the value
from the rate table.
Fix this by defining separate pll definitions for rk3066 with the correct
locking indices.
