These are some significant changes to generated code here, again with the aim of simplifying and improving code sharing.
Patches 1, 2-3, and 4-5 are independent in case any run into problems. Last big thing to do is machine check I'll try to send out tonight. After that we can start more unwinding of macros. [ BTW, the end game here is that each handler should be able to more or less specify _what_ it wants to do in macro flags, and the generation that takes care of _how_ will mostly be in a single place. e.g., Rather than some magic combination of EXCEPTION_<number>, it will just specify that it wants an early realmode handler with an alternate stack. ] Nicholas Piggin (5): powerpc/64s/exception: remove bad stack branch powerpc/64s/exception: optimise system_reset for idle, clean up non-idle case powerpc/64s/exception: sreset move trampoline ahead of common code powerpc/64s/exception: hmi remove special case macro powerpc/64s/exception: simplify hmi control flow arch/powerpc/include/asm/exception-64s.h | 7 - arch/powerpc/include/asm/paca.h | 2 + arch/powerpc/kernel/asm-offsets.c | 2 + arch/powerpc/kernel/exceptions-64s.S | 231 ++++++++--------------- arch/powerpc/xmon/xmon.c | 2 + 5 files changed, 86 insertions(+), 158 deletions(-) -- 2.20.1
