powerpc: Rework runlatch code

2012-03-08T23:55:02Z

This moves the inlines into system.h and changes the runlatch code to use the thread local flags (non-atomic) rather than the TIF flags (atomic) to keep track of the latch state. The code to turn it back on in an asynchronous interrupt is now simplified and partially inlined. Signed-off-by: Benjamin Herrenschmidt

powerpc: Rework die()

2011-12-08T03:02:23Z

Our die() code was based off a very old x86 version. Update it to mirror the current x86 code. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt

powerpc/cpuidle: cpuidle driver for pSeries

2011-12-08T02:56:31Z

This patch implements a back-end cpuidle driver for pSeries based on pseries_dedicated_idle_loop and pseries_shared_idle_loop routines. The driver is built only if CONFIG_CPU_IDLE is set. This cpuidle driver uses global registration of idle states and not per-cpu.

powerpc/cpuidle: Add cpu_idle_wait() to allow switching of idle routines

2011-12-08T02:54:58Z

This patch provides cpu_idle_wait() routine for the powerpc platform which is required by the cpuidle subsystem. This routine is required to change the idle handler on SMP systems. The equivalent routine for x86 is in arch/x86/kernel/process.c but the powerpc implementation is different. cpuidle_disable variable is to enable/disable cpuidle framework if power_save option is set during the boot time.

ptrace: unify show_regs() prototype

powerpc: Remove alloc_maybe_bootmem for zalloc version

2011-05-19T05:30:57Z

Replace all remaining callers of alloc_maybe_bootmem with zalloc_maybe_bootmem. The callsite in pci_dn is followed with a memset to clear the memory, and not zeroing at the other callsites in the celleb fake pci code could lead to following uninitialized memory as pointers or even freeing said pointers on error paths.
