Re: [PATCH v2 05/19] powerpc: interrupt handler wrapper functions

Hi Nicholas, I love your patch! Perhaps something to improve: [auto build test WARNING on powerpc/next] [also build test WARNING on v5.10-rc3 next-20201113] [If your patch is applied to the wrong git tree, kindly drop us a note. And when submitting patch, we suggest to use '--base' as documented

Re: [PATCH v2 03/19] powerpc: bad_page_fault, do_break get registers from regs

Hi, Quoting Nicholas Piggin : This also moves the 32s DABR match to C. I'm still not happy with that. What about the following instead ? diff --git a/arch/powerpc/kernel/entry_32.S b/arch/powerpc/kernel/entry_32.S index 8cdc8bcde703..6253c4acb46d 100644 --- a/arch/powerpc/kernel/entry_32.S +

[PATCH] powerpc/64s: Fix KVM system reset handling when CONFIG_PPC_PSERIES=y

pseries guest kernels have a FWNMI handler for SRESET and MCE NMIs, which is basically the same as the regular handlers for those interrupts. The system reset FWNMI handler did not have a KVM guest test in it, although it probably should have because the guest can itself run guests. Commit 4f5054
