sh: expose number of page table levels

2015-04-14T23:49:02+00:00

We would want to use number of page table level to define mm_struct.
Let's expose it as CONFIG_PGTABLE_LEVELS.

sh: build superh without CONFIG_EXPERT

2015-02-10T22:30:28+00:00

What sh4 actually wants is HAVE_PATA_PLATFORM, so select that instead.

PM: Eliminate CONFIG_PM_RUNTIME

2014-12-19T21:55:06+00:00

Having switched over all of the users of CONFIG_PM_RUNTIME to use
CONFIG_PM directly, turn the latter into a user-selectable option
and drop the former entirely from the tree.

gcov: enable GCOV_PROFILE_ALL from ARCH Kconfigs

2014-12-13T20:42:51+00:00

Following the suggestions from Andrew Morton and Stephen Rothwell,
Dont expand the ARCH list in kernel/gcov/Kconfig. Instead,
define a ARCH_HAS_GCOV_PROFILE_ALL bool which architectures
can enable.

set ARCH_HAS_GCOV_PROFILE_ALL on Architectures where it was
previously allowed + ARM64 which I tested.

PM / Kconfig: Do not select PM directly from Kconfig files

2014-12-03T23:50:53+00:00

It is not valid to select CONFIG_PM directly without selecting
CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME too, because that breaks
dependencies (ia64 does that) and it is not necessary to select
CONFIG_PM directly if CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME is
selected, because CONFIG_PM will be set automatically in that
case (sh does that).

Fix those mistakes.

kexec: remove CONFIG_KEXEC dependency on crypto

2014-08-29T23:28:16+00:00

New system call depends on crypto.  As it did not have a separate config
option, CONFIG_KEXEC was modified to select CRYPTO and CRYPTO_SHA256.

But now previous patch introduced a new config option for new syscall.
So CONFIG_KEXEC does not require crypto.  Remove that dependency.

sh: intc: Confine SH_INTC to platforms that need it

2014-08-22T03:28:16+00:00

Currently the sh-intc driver is compiled on all SuperH and
non-multiplatform SH-Mobile platforms, while it's only used on a limited
number of platforms:
  - SuperH: SH2(A), SH3(A), SH4(A)(L) (all but SH5)
  - ARM: sh7372, sh73a0

Drop the "default y" on SH_INTC, make all CPU platforms that use it
select it, and protect all sub-options by "if SH_INTC" to fix this.

kexec: load and relocate purgatory at kernel load time

2014-08-08T22:57:32+00:00

Load purgatory code in RAM and relocate it based on the location.
Relocation code has been inspired by module relocation code and purgatory
relocation code in kexec-tools.

Also compute the checksums of loaded kexec segments and store them in
purgatory.

Arch independent code provides this functionality so that arch dependent
bootloaders can make use of it.

Helper functions are provided to get/set symbol values in purgatory which
are used by bootloaders later to set things like stack and entry point of
second kernel etc.

Nothing sets function_trace_stop to disable function tracing anymore.
Remove the check for it in the arch code.
