powerpc: Don't skip ePAPR spin-table CPUs

2014-07-07T01:59:11Z

commit 6663a4fa6711050036562ddfd2086edf735fae21 upstream. Commit 59a53afe70fd530040bdc69581f03d880157f15a "powerpc: Don't setup CPUs with bad status" broke ePAPR SMP booting. ePAPR says that CPUs that aren't presently running shall have status of disabled, with enable-method being used to determine whether the CPU can be enabled. Fix by checking for spin-table, which is currently the only supported enable-method.

powerpc: Don't setup CPUs with bad status

2014-07-07T01:59:11Z

commit 59a53afe70fd530040bdc69581f03d880157f15a upstream. OPAL will mark a CPU that is guarded as "bad" in the status property of the CPU node. Unfortunatley Linux doesn't check this property and will put the bad CPU in the present map. This has caused hangs on booting when we try to unsplit the core. This patch checks the CPU is avaliable via this status property before putting it in the present map.

powerpc: Make boot_cpuid common between 32 and 64-bit

2014-04-07T00:33:14Z

Move the definition to setup-common.c and set the init value to -1 on both 32 and 64-bit (it was 0 on 64-bit). Additionally add a check to prom.c to garantee that the init value has been udpated after the DT scan. Signed-off-by: Benjamin Herrenschmidt

powerpc: Fix endian issue in setup-common.c

2013-12-13T04:48:34Z

During on LE boot we see: Partition configured for 1073741824 cpus, operating system maximum is 2048. Clearly missing a byteswap here. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt

powerpc: Move local setup.h declarations to arch includes

2013-10-30T05:00:31Z

Move the few declarations from arch/powerpc/kernel/setup.h into arch/powerpc/include/asm/setup.h. This resolves a sparse warning for arch/powerpc/mm/numa.c which defines do_init_bootmem() but can't include the setup.h header in the prior path. Resolves: arch/powerpc/mm/numa.c:998:13: warning: symbol 'do_init_bootmem' was not declared. Should it be static? Signed-off-by: Robert C Jennings Signed-off-by: Benjamin Herrenschmidt

powerpc/watchdog: move booke watchdog param related code to setup-common.c

2012-07-11T12:44:03Z

Currently, BOOKE watchdog code for checking "wdt" and "wdt_period" is in setup_32.c, it cannot be used in 64-bit, so move it to a common place setup-common.c, which will be shared by 32-bit and 64-bit. Also, replace the simple_strtoul with kstrtol. Signed-off-by: Shaohui Xie Signed-off-by: Kumar Gala
