powerpc: Fix default_machine_crash_shutdown #ifdef build failure
Is this patch upstream in Linus's tree? If so, what is the git commit
id? If not, why isn't it needed there?
[...]
the #ifdef CONFIG_PPC_STD_MMU_64 bits are taken from upstream commit
b3df895aebe09 and the build failure incase of SMP=n is from the
upstream commit c2be05481f61.
Should I resend the patch in rebase format including both the commits
id and message.
Yes, please do.
Hi Greg,
Resending the patch with commit id and message included. Please let
me know, incase the patch needs any other changes to be made.
powerpc: Fix default_machine_crash_shutdown #ifdef build failure
This patch introduces #ifdef bits from below commits, to fix the
build failure on powerpc caused by crash_kexec_wait_realmode()
when compiled with !SMP.
Commit: c2be05481f6125254c45b78f334d4dd09c701c82 upstream
powerpc: Fix default_machine_crash_shutdown #ifdef botch
crash_kexec_wait_realmode() is defined only if CONFIG_PPC_STD_MMU_64
and CONFIG_SMP, but is called if CONFIG_PPC_STD_MMU_64 even if !CONFIG_SMP.
Fix the conditional compilation around the invocation.
Commit: b3df895aebe091b1657a42a8c859bd49fc96646b upstream
powerpc/kexec: Add support for FSL-BookE
This adds support kexec on FSL-BookE where the MMU can not be simply
switched off. The code borrows the initial MMU-setup code to create the
identical mapping mapping. The only difference to the original boot code
is the size of the mapping(s) and the executeable address.
The kexec code maps the first 2 GiB of memory in 256 MiB steps. This
should work also on e500v1 boxes.
SMP support is still not available.
(Kumar: Added minor change to build to ifdef CONFIG_PPC_STD_MMU_64 some
code that was PPC64 specific)
