* mips: do not save variables in "hi" or "lo" across system callsDaniel Jacobowitz2009-10-171-2/+2
| | | | | | | | | | The kernel does not save these registers across system calls. GCC 4.4 has gotten more aggressive about using them for temporary variables, so this shows up as intermittent crashes if you use a recent compiler.

* syscall: unify part 2: NCS varietyMike Frysinger2009-07-091-2/+2
| | | | | | | | Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* syscall: unify common syscall definesMike Frysinger2009-07-091-67/+0
| | | | | | | | | | Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports.

| | | | | | | | | In a recent post to linux-mips ML (and libc-alpha ML), a problem with inline syscalls was reported. http://www.linux-mips.org/archives/linux-mips/2004-10/msg00142.html It seems uClibc should be fixed also for newer gcc. Here is a patch.
