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.

x86: fix usage of .section .sched.text in assembler code
Without this patch the linker will generate a section
named .sched.text.1 which is unexpected.
This is because the gcc generated section has "ax" but the
assembler usage of .sched.text lacks the "ax" specifier.

It would be better to have a definition we could use from
assembler code but I did not find a suitable header
file for it.
