Subject: [PATCH 00/17] powerpc: Remove STACK_FRAME_OVERHEAD
Date: Sun, 27 Nov 2022 22:49:25 +1000 [thread overview]
Message-ID: <20221127124942.1665522-1-npiggin@gmail.com> (raw)
Since RFC:
- Fix a compile bug.
- Fix BookE KVM properly. Hopefully -- I don't have a BookE
KVM environment to test. Can QEMU do it? Is it still tested?
- Drop the last two patches that changed the stack layout, they
can be done later.
- Drop the load/store-multiple change to 32-bit.
Thanks,
Nick
Nicholas Piggin (17):
KVM: PPC: Book3E: Fix CONFIG_TRACE_IRQFLAGS support
powerpc/64: Remove asm interrupt tracing call helpers
powerpc/perf: callchain validate kernel stack pointer bounds
powerpc: Rearrange copy_thread child stack creation
powerpc/pseries: hvcall stack frame overhead
powerpc: simplify ppc_save_regs
powerpc: add definition for pt_regs offset within an interrupt frame
powerpc: add a definition for the marker offset within the interrupt
frame
powerpc: Rename STACK_FRAME_MARKER and derive it from frame offset
powerpc: add a define for the user interrupt frame size
powerpc: add a define for the switch frame size and regs offset
powerpc: copy_thread fill in interrupt frame marker and back chain
powerpc: copy_thread add a back chain to the switch stack frame
powerpc: split validate_sp into two functions
powerpc: allow minimum sized kernel stack frames
powerpc/64: ELFv2 use minimal stack frames in int and switch frame
sizes
powerpc: remove STACK_FRAME_OVERHEAD
