2009-07-10sched: INIT_PREEMPT_COUNTPeter Zijlstra
Pull the initial preempt_count value into a single definition site. Maintainers for: alpha, ia64 and m68k, please have a look, your arch code is funny. The header magic is a bit odd, but similar to the KERNEL_DS one, CPP waits with expanding these macros until the INIT_THREAD_INFO macro itself is expanded, which is in arch/*/kernel/init_task.c where we've already included sched.h so we're good.

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.

2009-07-06microblaze: 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.

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.

2009-07-06microblaze: use the generic lib/checksum.cRemis Lima Baima
The microblaze checksum code is mostly identical to the asm-generic+lib version, so use that instead. Signed-off-by: Remis Lima Baima <remis.developer@googlemail.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-07-06microblaze: fall back on generic header files for the ABIArnd Bergmann
Almost all of the ABI relevant header files now have generic versions, so use those now in order to reduce the amount of architecture specific code. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>

2009-07-05powerpc/44x: Fix build error with -Werror for Warp platformJosh Boyer
With -Werror enabled during the build, the warp.c file fails to build due to the temp_isr function not containing a return statement. This fixes the build error and documents that the function never returns. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
2009-07-06powerpc/4xx: Have Warp take advantage of GPIO LEDs default-state = keepSean MacLennan
The GPIO LEDS driver now has a default state of "keep". Update the Warp DTS and platform file to take advantage of this new state. This removes the hardcoding of the two LEDs on the Warp. Signed-off-by: Sean MacLennan <smaclennan@pikatech.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
