As discussed in
https://patchwork.kernel.org/patch/1581581/
the driver core remove function needs to always succeed. This means we need
to know that the device can be successfully removed before acpi_bus_trim /
acpi_bus_hot_remove_device are called. This can cause panics when OSPM-initiated
eject
A new argument is added to acpi_bus_trim, which indicates if we are preparing
for removal or performing the actual ACPI removal. This is needed for safe
removal of memory devices.
The argument change would not be needed if the existing argument rmdevice of
acpi_bus_trim could be used instead.

Provide an ARM implementation of syscall_get_arch. This is a pre-requisite
for CONFIG_HAVE_ARCH_SECCOMP_FILTER.

On tracehook-friendly platforms, a system call number of -1 falls
through without running much code or taking much action.
ARM is different. This adds a short-circuit check in the trace path to
avoid any additional work, as suggested by Russell King, to make sure
that ARM behaves the same way as

The overall aim of this series is to allow ARM (or indeed any) timer
drivers to be moved into drivers/clocksource without requiring a
struct or function prototype for each individual driver in include/linux.
The intent is eventually to create a single e.g.
