2009-12-14microblaze: Remove saving and restoring before calling signal codeMichal Simek
Saving is done in SAVE_STATE macros that's why another save discard previous saved value. This change has no effect to normal programs because they ends in any exception and they are killed. On the other side has effect on debugging. Signed-off-by: Michal Simek <monstr@monstr.eu>

2009-07-06microblaze: use generic syscalls.hArnd Bergmann
The prototypes in syscalls.h all make sense for microblaze, but for some of them, the actual implementation in sys_microblaze.c needs to be adapted. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-07-06microblaze: clean up signal handlingArnd Bergmann
When legacy signal handling is disabled, the arch/microblaze/kernel/signal.c implementation can be much simpler, as most of it is handled generically from kernel/signal.c. This is also a prerequisite for using the generic asm/unistd.h, which does not provide __NR_sigreturn, because this macro is referenced by the current signal.c implementation.
