Sonic Zhang 99a5b2878b Blackfin: add new cacheflush syscall ... Flushing caches sometimes requires anomaly workarounds which require supervisor-only insns. Normally we don't need to flush caches from userspace so this isn't a problem, but when gcc generates trampolines on the stack, we do. So add a new syscall for gcc to use modeled after the mips version. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>		2010-10-22 03:48:59 -04:00
