microblaze: bury asm/namei.h

2011-11-21T21:48:28Z

altroot support has been gone for years, along with arch/*/asm/namei.h; looks like a dummy survivor that sat it out in microblaze tree... Signed-off-by: Al Viro

microblaze: Remove __ARCH_WANT_INTERRUPTS_ON_CTXSW usage

2011-10-14T10:28:42Z

As far as I can tell the only reason microblaze has __ARCH_WANT_INTERRUPTS_ON_CTXSW is because it initializes new task state with interrupts enabled so that on switch_to() interrupts get enabled. So change copy_thread() to clear MSR_IE instead of set it, this will ensure switch_to() will always keep IRQs disabled. The scheduler will disable IRQs when taking rq->lock in schedule() and enable IRQs in finish_lock_switch() after its done its magic. This leaves ARM the only __ARCH_WANT_INTERRUPTS_ON_CTXSW user.

microblaze: Use delay slot in __strnlen_user, __strncpy_user

2011-10-14T10:24:34Z

Use delay slot to speedup if maxlen is zero. Signed-off-by: Michal Simek

microblaze: Remove NET_IP_ALIGN from system.h

2011-10-14T10:24:33Z

Use default value (which is the same) from include/linux/skbuff.h. Signed-off-by: Michal Simek

microblaze: Add __ucmpdi2() helper function

2011-10-14T10:24:32Z

Add missing __ucmpdi2 helper function. Error log: kernel/built-in.o: In function `print_graph_duration': : undefined reference to `__ucmpdi2' kernel/built-in.o: In function `print_graph_duration': : undefined reference to `__ucmpdi2' Based on MIPS code. Signed-off-by: Michal Simek

microblaze: Raise SIGFPE/FPE_INTDIV for div by zero

2011-10-14T10:24:31Z

It fixes the signal nr raised for divizion by zero from SIGILL to SIGFPE, in accordance to POSIX and other archs. This came up due to a failed test in the GCC testsuite. Signed-off-by: Edgar E. Iglesias

microblaze: Switch ELF_ARCH code to 189

2011-10-14T10:24:31Z

Switch arch code to 189, the registered code in the upstream version of binutils. Continue to accept the experimental 0xbaab. Signed-off-by: Edgar E. Iglesias Signed-off-by: Michal Simek
