powerpc: Move {d,i,u}cache_bsize definitions to a common place

2017-02-06T08:46:04+00:00

The variables are defined twice in setup_32.c and setup_64.c, do it
once in setup-common.c instead

powerpc/iommu: Pass mm_struct to init/cleanup helpers

2016-12-02T03:38:27+00:00

We are going to get rid of @current references in mmu_context_boos3s64.c
and cache mm_struct in the VFIO container. Since mm_context_t does not
have reference counting, we will be using mm_struct which does have
the reference counter.

This changes mm_iommu_init/mm_iommu_cleanup to receive mm_struct rather
than mm_context_t (which is embedded into mm).

This should not cause any behavioral change.

Factor out a small bit of common code in machine_restart(),
machine_power_off() and machine_halt().

powerpc: Move cpu_has_feature() to a separate file

2016-08-01T01:15:03+00:00

We plan to use jump label for cpu_has_feature(). In order to implement
this we need to include the linux/jump_label.h in asm/cputable.h.

Unfortunately if we do that it leads to an include loop. The root of the
problem seems to be that reg.h needs cputable.h (for CPU_FTRs), and then
cputable.h via jump_label.h eventually pulls in hw_irq.h which needs
reg.h (for MSR_EE).

So move cpu_has_feature() to a separate file on its own.

powerpc: Merge 32-bit and 64-bit setup_arch()

2016-07-21T09:17:46+00:00

There is little enough differences now.

mpe: Add a/p/k/setup.h to contain the prototypes and empty versions of
functions we need, rather than using weak functions. Add a few other
empty versions to avoid as many #ifdefs as possible in the code.

powerpc: Re-order setup_panic()

2016-07-21T09:17:23+00:00

Do it right after probe_machine() since it's about testing ppc_md,
and put the test in the common code.

powerpc: Ensure that ppc_md is empty before probing for machine type

2016-07-21T08:59:21+00:00

Anything in there will be overwritten, so it helps catching nasty
bugs if we check that it's indeed full of NULL's before we do so.

powerpc: Remove unnecessary CONFIG_SMP #ifdefs

2016-05-11T11:54:01+00:00

The code in machine_restart/power_off/halt() includes #ifdefs around
calls to smp_send_stop(), however these are not required as
include/linux/smp.h includes an empty version of this function for
CONFIG_SMP=n builds.
