64ac24e738 Generic semaphore implementation
Semaphores are no longer performance-critical, so a generic C
implementation is better for maintainability, debuggability and
extensibility.  Thanks to Peter Zijlstra for fixing the lockdep
warning.  Thanks to Harvey Harrison for pointing out that the
unlikely() was unnecessary.

9bbafce2ee sh: Fix occasional FPU register corruption under preempt.
Presently with preempt enabled there's the possibility to be preempted
after the TIF_USEDFPU test and the register save, leading to bogus
state post-__switch_to(). Use an explicit preempt_disable()/enable()
pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86
change.

49a5ba46c5 sh: Use relative paths for mach/cpu symlinks.
When building the kernel without passing the O= command line parameter
there's no point to use absolute paths for them.

Usually relative paths are preferred because they survive directory
moves, work across networked file systems and chrooted environments.

Absolute paths are still used if an output directory is given.

6c0602b8dd sh: Fix up the address error exception handler for SH-2.

register state from the stack and skips over the first register, skewing
the rest. Fix up the math here so that the proper register state is

b2d7c7f7a6 arch/sh/drivers/dma/dma-sh.c: Correct use of ! and &
In commit e6bafba5b4, a bug was fixed that
involved converting !x & y to !(x & y).  The code below shows the same
pattern, and thus should perhaps be fixed in the same way.

This is not tested and clearly changes the semantics, so it is only
something to consider.

The semantic patch that makes this change is as follows:

96de1a8f02 serial: Move asm-sh/sci.h to linux/serial_sci.h.
This header is needed on other architectures as well (namely h8300),
which currently fails to build without this in place. Rather than
duplicating the port definition completely there, just move this to a
common location instead.

This should get h8300 working again for 2.6.25, in addition to the
changes already pushed by Sato-san in -rc2.
