b82ba2f011 MIPS: Respect the legacy syscall restart convention. 
That convention requires the instruction immediately preceding SYSCALL
to initialize $v0 with the syscall number.  Then if a restart triggers,
$v0 will have been clobbered by the syscall interrupted, and needs to be
reinititalized.  The kernel will decrement the PC by 4 before switching
back to the user mode so that $v0 has been reloaded before SYSCALL is
executed again.  This implies the place $v0 is loaded from must be
preserved across a syscall, e.g. an immediate, static register, stack
slot, etc.

The restriction was lifted with Linux 2.6.36 kernel release and no
special requirements are placed around the SYSCALL instruction anymore,
however we still support older kernel binaries.

89570c6269 mips: clear condition bit 23 in fpu too 
We've been carrying this in Gentoo for quite a long time to fix some test
failures that people hit.

Original message:
	> make[4]: *** [/glibc/glibc-package-2.3/mips-linux/obj/math/test-fpucw.out] Error 1
	This test fails since the read back fpu control word is 0x80000 instead
	of 0x0. I wonder if this patch is correct:
	...
	which additionally masks out the condition bit 23 - note that the other
	condition bits (25-31) are masked out too?

30f696374d Fifth argument of la_pltenter() is not constant. 
The original runtime linker auditing interface described
by Solaris allows the 5th argument of la_pltenter() to be
modified. This patch cleans up the ldsodefs.h definitions
such that the 5th argument is not constant.

At one point the 5th argument *was* constant but this was
changed with commit 2413fdba7a.
This patch updates alpha, ia64, mips, sh and sparc with similar
changes.
