Some exception entry requires DAR and/or DSISR to be saved into the paca exception save area. Add options to the standard exception macros for these. Generated code changes slightly due to code structure. - 554: a6 02 72 7d mfdsisr r11 - 558: a8 00 4d f9 std r10,168(r13) - 55c: b0 00 6d 91 stw r11,176(r13) + 554: a8 00 4d f9 std r10,168(r13) + 558: a6 02 52 7d mfdsisr r10 + 55c: b0 00 4d 91 stw r10,176(r13) Signed-off-by:

Restore all SPRs and CR up-front, these are longer latency instructions. Move register restore around to maximise pairs of adjacent loads (e.g., restore r0 next to r1). Signed-off-by:

Duplicate the hmi windup code for both cases, rather than to put a special case branch in the middle of it. Remove unused label. This helps with later code consolidation. Signed-off-by:

Move in_mce decrement earlier before registers are restored (but still after RI=0). This helps with later consolidation. Signed-off-by:

All supported 64s CPUs support mtmsrd L=1 instruction, so a cleanup can be made in sreset and mce handlers. Signed-off-by:

Move SPR reads ahead of writes. Real mode entry that is not a KVM guest is rare these days, but bad practice propagates. Signed-off-by:

syscall / hcall entry unnecessarily differs between KVM and non-KVM builds. Move the SMT priority instruction to the same location (after INTERRUPT_TO_KERNEL). Signed-off-by:

Generally, macros that result in instructions being expanded are indented by a tab, and those that don't have no indent. Fix the obvious cases that go contrary to style. No generated code change. Signed-off-by:

After the previous cleanup, it becomes possible to consolidate some common code outside the runtime alternate patching. Also remove unused labels. This results in some code change, but unchanged runtime instruction sequence. Signed-off-by:

Many of these macros just specify 1-4 lines which are only called a few times each at most, and often just once. Remove this indirection. No generated code change. Signed-off-by:

More cases of code insertion via macros that does not add a great deal. All the additions have to be specified in the macro arguments, so they can just as well go after the macro. No generated code change. Signed-off-by:

The aim is to reduce the amount of indirection it takes to get through the exception handler macros, particularly where it provides little code sharing. No generated code change. Signed-off-by:

Rather than pass in the soft-masking and KVM tests via macro that is passed to another macro to expand it, switch to usig gas macros and conditionally expand the soft-masking and KVM tests. The system reset with its idle test is open coded as it is a one-off. No generated code change. Signed-off-by:

The sreset handler KVM test theoretically should not depend on P7. In practice KVM now only supports P7 and up so no real bug fix, but this change is made now so the quirk is not propagated through cleanup patches. Signed-off-by:

- Re-name the macros to _REAL and _VIRT suffixes rather than no and _RELON suffix. - Move the macro definitions together in the file. - Move RELOCATABLE ifdef inside the _VIRT macro. Further consolidation between variants does not buy much here. No generated code change. Signed-off-by:
