sctp: fix compile error due to sysctl mismerge

I messed up the merge in d7fc02c7bae7b1cf69269992cf880a43a350cdaa, where
the conflict in question wasn't just about CTL_UNNUMBERED being removed,
but the 'strategy' field is too (sysctl handling is now done through the
/proc interface, with no duplicate protocols for reading the data).

Revert "pata_sis: Implement MWDMA for the UDMA 133 capable chips"

This reverts commit f20941f334d8fdb6b598658979709b4e94cd034b.

Sergei Shtylyov notes "You call min() on uncomparables [in
mwdma_clip_to_pio()], i.e. mwdma_to_pio[] contains XFER_PIO_* and
adev->pio_mode - XFER_PIO_0 yields you a mode number.  Thus the second
argument will always "win" as a minimal one"

Bartlomiej Zolnierkiewicz adds "There are more issues with the patch related
to mwdma_clip_to_pio().  The function can return values between 0 and
4 which obviously won't work well for the new code below for values
>2 (i.e. resulting in out-of-bounds array access for the common-case
of dev->pio_mode == XFER_PIO_4)."

update MWDMA mode masks.

fbdev: atafb - add palette register check

Add check if palette register number is in correct range
for few drivers which miss it. The regno value comes
indirectly from user space.

m68k: Remove the BKL from sys_execve

This seems like a copy-and-paste from code that no-longer needs the BKL
Just remove it.

10 years agocfq-iosched: use call_rcu() instead of doing grace period stall on queue exit
Jens Axboe [Sun, 6 Dec 2009 08:54:19 +0000]
cfq-iosched: use call_rcu() instead of doing grace period stall on queue exit

After the merge of the IO controller patches, booting on my megaraid
box ran much slower. Vivek Goyal traced it down to megaraid discovery
creating tons of devices, each suffering a grace period when they later
kill that queue (if no device is found).

So lets use call_rcu() to batch these deferred frees, instead of taking
the grace period hit for each one.

10 years agosparc: Set UTS_MACHINE correctly.
David S. Miller [Sun, 6 Dec 2009 01:17:55 +0000]
sparc: Set UTS_MACHINE correctly.

"ARCH" can be just about anything, so we shouldn't end up
with UTS_MACHINE of "sparc" in a 64-bit kernel build just
because someone set the personality using 'sparc32' or
similar.  CONFIG_SPARC64 drives the compilation and
therefore provides the definitive value, not "ARCH".

This mirrors commit 8c6531f7a99f29ba8817ffb12cc9ecf190049bd6
(x86: correctly set UTS_MACHINE for "make ARCH=x86")
