Back in 2005 when the ppc/ppc64 merge started, we used to build the
kernel code in arch/powerpc but use the boot code from arch/ppc or
arch/ppc64 depending on whether we were building for 32 or 64-bit.
Originally we called the boot Makefile passing ARCH=$(OLDARCH), where
OLDARCH was ppc or ppc64.

If we're using if_changed then we must depend on FORCE, so that
if_changed gets a chance to check if something changed.

Now that we don't set ARCH incorrectly when calling the boot Makefile,
we can use the generic cpp_lds_S rule for converting our zImage.lds.S
into zImage.lds.
The main advantage of using the generic rule is that it correctly uses
if_changed, which means we correctly regener

The existing code doesn't handle the case when CPU which was in a
hardware-idle state (nap,sleep,winkle on POWER8 and various stop
states on POWER9) gets woken up due to a System Reset interrupt.
This patch checks if the CPU was woken up due to System Reset, in

This small patch series introduces support for a driver to increase the
VPD wait timeout for devices with slower interfaces.
The series is based on v4.9-rc6 and is intended for v4.10.

The PCI core uses a fixed 50ms timeout when waiting for VPD accesses to
complete. When an access does not complete within this period, a warning
is logged and an error returned to the caller.

Some IBM CXL devices can take up to ~120ms to complete a VPD access
