      [PATCH] ahci: ignore PORT_IRQ_IF_ERR on JMB controllers · 41669553
      Tejun Heo authored 
      JMicron AHCI controllers set PORT_IRQ_IF_ERR on device errors.  The
IRQ status bit indicates interface error or protocol mismatch and ahci
driver interprets it into AC_ERR_ATA_BUS.  So, whenever an ATAPI
device raises check condition, ahci interprets it as ATA bus error and
thus resets it which, in turn, raises check condition thus creating a
reset loop and rendering the device unuseable.

This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when
interpreting error condition.

      Fix 'ALIGN()' macro, take 2 · 2ea58144
      Linus Torvalds authored 
      You wouldn't think that doing an ALIGN() macro that aligns something up
to a power-of-two boundary would be likely to have bugs, would you?

But hey, in the wonderful world of mixing integer types, you have to be
careful.  This just makes sure that the alignment is interpreted in the
same type as the thing to be aligned.

Thanks to Roland Dreier, who noticed that the amso1100 driver got broken
by the previous fix (that just extended the mask to "unsigned long", but
was still broken in "unsigned long long" - it just happened to be the
same on 64-bit architectures).

See commit 4c8bd7ee for the history of
bugs here...

      [PATCH] Fix incorrent type of flags in <asm/semaphore.h> · c9c3b86f
      Kyle McMartin authored 
      I still think using BUILD_BUG_ON() is unacceptable, especially given how
vague the error message was.

      Revert "[PATCH] Enforce "unsigned long flags;" when spinlocking" · b8e6ec86
      Linus Torvalds authored 
      This reverts commit ee3ce191, since it
broke on at least ARM, MIPS and PA-RISC due to complicated header file
dependencies.

Conflicts in include/linux/spinlock.h (due to the "nested" variety
fixes) fixed up by hand.
