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 arch/powerpc/Kconfig | 2 +- arch/powerpc/include/asm/exception-64e.h | 4 +- arch/powerpc/include/asm/page.h | 7 +-- arch/powerpc/include/asm/smp.h | 1 + arch/powerpc/kernel/crash.c | 6 +-- arch/powerpc/kernel/exceptions-64e.S | 17 +++--- arch/powerpc/kernel/head_64.S | 58 ++++++++++++++++++-- arch/powerpc/kernel/machine_kexec_64.c | 19 +++++++ arch/powerpc/kernel/misc_64.S | 62 ++++++++++++++++++++- arch/powerpc/kernel/paca.c | 6 ++- arch/powerpc/kernel/setup_64.c | 22 +++++++- arch/powerpc/mm/fsl_booke_mmu.c | 35 ++++++++---- arch/powerpc/mm/mmu_decl.h | 4 +- arch/powerpc/mm/tlb_nohash.c | 41 +++++++++++--- arch/powerpc/mm/tlb_nohash_low.S | 63 ++++++++++++++++++++++ arch/powerpc/platforms/85xx/corenet_generic.c | 4 ++ arch/powerpc/platforms/85xx/smp.c | 77 +++++++++++++++++++++++++-- drivers/crypto/caam/Kconfig | 2 +- 18 files changed, 385 insertions(+), 45 deletions(-) -- 2.1.4
