Commit 221af7f87b9 ("Split 'flush_old_exec' into two functions") split
the function at the point of no return - ie right where there were no
more error cases to check. That made sense from a technical standpoint,
but when we then also combined it with the actual personality setting
going in between flush_old_exec() and setup_new_exec(), it needs to be a
bit more careful.
In particular, we need to make sure that we really flush the old
personality bits in the 'flush' stage, rather than later in the 'setup'
stage, since otherwise we might be flushing the _new_ personality state
that we're just setting up.
So this moves the flags and personality flushing (and 'flush_thread()',
which is the arch-specific function that generally resets lazy FP state
etc) of the old process into flush_old_exec(), so that it doesn't affect
any state that execve() is setting up for the new process environment.
This was reported by Michal Simek as breaking his Microblaze qemu
environment.

This patch improves disable_controller() in the r8a66597-hdc
driver to disable all interrupts and clear status flags. It
also makes sure that disable_controller() is called during
probe(). This fixes the relatively rare case of unexpected
pending interrupts after kexec reboot.

The spi_sh_msiof.c driver presently misconfigures REDG and TEDG. TEDG==0
outputs data at the **rising edge** of the clock and REDG==0 samples data
at the **falling edge** of the clock. Therefore for SPI, TEDG must be
equal to REDG, otherwise the last byte received is not sampled in SPI
mode 3.
This brings the driver in line with the SH7723 HW Reference Manual
settings documented in Figures 20.20 and 20.21 ("SPI Clock and data
timing").

As the padlock driver for SHA uses a software fallback to perform

Otherwise hmac which depends on import/export for prehashing will

No other driver does anything remotely like this that I know of except
for the tty drivers, and I can't see any reason for random/urandom to do
it. In fact, it's a (trivial, harmless) timing information leak. And
obviously, it generates power- and flash-cycle wasting I/O, especially
if combined with something like hwrngd. Also, it breaks ubifs's
expectations.

DBDMA descriptors need to be located at 32-byte aligned addresses;
however kmalloc in conjunction with the SLAB allocator and
CONFIG_DEBUG_SLUB enabled doesn't deliver any. The dbdma code works
around that by allocating a larger area and realigning the start
address within it.
When freeing a channel however this adjustment is not taken into
account which results in an oops:
Kernel bug detected[#1]:
[...]
Call Trace:
[<80186010>] cache_free_debugcheck+0x284/0x318
[<801869d8>] kfree+0xe8/0x2a0

[<80189018>] sys_close+0x9c/0xe4
[<801022a0>] stack_done+0x20/0x3c
Fix this by recording the address delivered by kmalloc() and using
it as parameter to kfree().
This fix is only necessary with the SLAB allocator and CONFIG_DEBUG_SLAB
enabled; non-debug SLAB, SLUB do return nicely aligned addresses,
debug-enabled SLUB currently panics early in the boot process.

ince gfs2 writes the rindex file a block at a time, and releases the
exclusive lock after each block, it is possible that another process
will grab the lock in the middle of the write. Since rindex entries are
not an even divisor of blocks, that other process may see partial
entries. On grows, this is fine. The process can simply ignore the the
partial entires. Previously, the code withdrew when it saw partial
entries. Now it simply ignores them.

If an error happen in r600_blit_prepare_copy report it rather
than WARNING and keeping execution. For instance if ib allocation
failed we did just warn about but then latter tried to access
NULL ib ptr causing oops. This patch also protect r600_copy_blit
with a mutex as otherwise one process might overwrite blit temporary
data with new one possibly leading to GPU lockup.
Should partialy or totaly fix:

booting a Lenovo W500 with LVDS + DP outputs showed up a TODO we had
on our list, to pick a correct digital encoder block. The LVTMA
encoder requires the second digital encoder, all others can use any
encoder at all.
This fixes the digital encoder selection logic to enable LVDS/DP combos
to work okay.
V2: fix silly addition of connector dig_block and cleanup the other
places in the code that pick the encoder.
V3: rename to dig_encoder and clean up further - also fix
the picking algorithm.

On the W500 we have UNIPHY routed to both DVI and DP, this seems
to always pick the DVI connector which means link training fails.
Switch to using active device to pick the connector, this seems
like it should be safe from a code review, and it fixes things
a bit more here.
