[PATCH] EDAC/mv64x60: Remove orphan mv64x60 driver

The mv64x60 EDAC driver depends on CONFIG_MV64X60. But that symbol is not user-selectable, and the last code that selected it was removed with the C2K board support in 2018, see: 92c8c16f3457 ("powerpc/embedded6xx: Remove C2K board support") That means the driver is now dead code, so remove

[PATCH 2/2] powerpc/powernv/idle: Restore CIABR after idle for Power9

On Power9, CIABR is lost after idle. This means that instruction breakpoints set by xmon which use CIABR do not work. Fix this by restoring CIABR after idle. Signed-off-by: Jordan Niethe --- arch/powerpc/platforms/powernv/idle.c | 3 +++ 1 file changed, 3 insertions(+) diff --git

[PATCH 1/2] powerpc/book3s64/kexec: Clear CIABR on kexec

The value in CIABR persists across kexec which can lead to unintended results when the new kernel hits the old kernel's breakpoint. For example: 0:mon> bi $loadavg_proc_show 0:mon> b typeaddress 1 inst c0519060 loadavg_proc_show+0x0/0x130 0:mon> x $ kexec -l
