* microblaze: Remove rt_sigsuspend wrapperMichal Simek2009-12-141-1/+0
| | | | | | Generic rt_sigsuspend syscalls doesn't need any asm wrapper. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Support for WB cacheMichal Simek2009-12-141-2/+28
| | | | | | | | | | | Microblaze version 7.20.d is the first MB version which can be run on MMU linux. Please do not used previous version because they contain HW bug. Based on WB support was necessary to redesign whole cache design. Microblaze versions from 7.20.a don't need to disable IRQ and cache before working with them that's why there are special structures for it. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Ptrace notifying from signal codeMichal Simek2009-12-141-0/+4
| | | | | | | | | After the signal frame is set up on the userspace stack, ptrace() should be given an opportunity to single-step into the signal handler FRV, Blackfin, mn10300 and UM. Worth to look at that patches. Signed-off-by: Michal Simek <monstr@monstr.eu>
* headers: smp_lock.h reduxAlexey Dobriyan2009-07-121-1/+0
| | | | | | | | | | | | | * Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* microblaze: use generic syscalls.hArnd Bergmann2009-07-061-1/+1
| | | | | | | | | 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>
* microblaze: clean up signal handlingArnd Bergmann2009-07-061-136/+36
| | | | | | | | | | | | | | | 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.

* microblaze_mmu_v2: Update signal returning addressMichal Simek2009-05-261-0/+8

* microblaze: prepare signal handling for generic unistd.hMichal Simek2009-05-211-76/+3
| | | | | | | | | We need to define set_restore_sigmask() in order to get pselect and ppoll. Also, the setup_frame function can not be used when __NR_sigreturn is not defined. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: fix __user annotationsArnd Bergmann2009-05-211-12/+10
| | | | | | | | | | | | The microblaze signal handling code gets some __user pointers wrong, as shown by sparse. This adds the annotations where appropriate and change sys_rt_sigreturn to correctly pass a user stack down to do_sigaltstack instead of a kernel structure.

* microblaze: Add STATE_SAVE_ARG_SPACE for noMMU kernel tooMichal Simek2009-04-231-4/+10
| | | | | | | For noMMU kernel this change nothing bring but this change helps with MMU synchronization. Signed-off-by: Michal Simek <monstr@monstr.eu>
