This makes the VIC resume from suspend flagged IRQ:s identical to the flags indicating all possible interrupts. This is perhaps not the optimal setting but setting it to 0 makes the system suspend and never come back again (all IRQ sources masked off).

2009-07-08powerpc: Fix spin_event_timeout() to be robust over context switchesGrant Likely
Current implementation of spin_event_timeout can be interrupted by an IRQ or context switch after testing the condition, but before checking the timeout. This can cause the loop to report a timeout when the condition actually became true in the middle. This patch adds one final check of the condition upon exit of the loop if the last test of the condition was still false.

2009-07-07[S390] udelay: disable lockdep to avoid false positivesHeiko Carstens
Our udelay implementation enables interrupts to receive a special timer interrupt regardless of the context it is called from. This might lead to false positive lockdep reports. Since lockdep isn't aware of the fact that only a single interrupt source is enabled it warns about possible deadlocks that in reality won't happen, like the one below. To fix this disable lockdep before enabling interrupts.

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.

2009-07-06microblaze: convert all simple headers to use asm-genericRemis Lima Baima
All the simple microblaze header files were adapted to use their asm-generic implementations. These files are more simple and were quite straightforward to change. fb.h, vga.h and parport.h previously did not exist, using the generic version makes it possible to build more drivers successfully in allyesonfig.
