[RFC PATCH 00/17] powerpc/fsl-book3e-64: kexec/kdump support

[Scott Wood]

This patchset adds support for kexec and kdump to e5500 and e6500 based
systems running 64-bit kernels.  It depends on
http://patchwork.ozlabs.org/patch/496952/ ("powerpc/fsl-booke-64: Allow
booting from the secondary thread") and the kexec-tools patch
http://lists.infradead.org/pipermail/kexec/2015-July/014048.html ("ppc64:
Add a flag to tell the kernel it's booting from kexec").

Scott Wood (11):
  powerpc/85xx: Load all early TLB entries at once
  powerpc/85xx: Don't use generic timebase sync on 64-bit
  crypto: caam: Blacklist CAAM when kexec is enabled
  powerpc/fsl-corenet: Disable coreint if kexec is enabled
  powerpc/fsl-booke-64: Don't limit ppc64_rma_size to one TLB entry
  powerpc/e6500: kexec: Handle hardware threads
  powerpc/book3e/kdump: Enable crash_kexec_wait_realmode
  powerpc/book3e-64: Don't limit paca to 256 MiB
  powerpc/book3e-64/kexec: Enable SMP release
  powerpc/booke: Only use VIRT_PHYS_OFFSET on booke32
  powerpc/book3e-64/kexec: Set "r4 = 0" when entering spinloop

Tiejun Chen (6):
  powerpc/85xx: Implement 64-bit kexec support
  powerpc/book3e-64: rename interrupt_end_book3e with __end_interrupts
  powerpc/booke64: Fix args to copy_and_flush
  powerpc/book3e: support CONFIG_RELOCATABLE
  powerpc/book3e-64/kexec: create an identity TLB mapping
  powerpc/book3e-64: Enable kexec
