powerpc: Fix 'intra_function_call not a direct call' warning
The following build warning have been reported:
arch/powerpc/kvm/book3s_hv_rmhandlers.o: warning: objtool: .text+0xe84: intra_function
powerpc: Fix 'intra_function_call not a direct call' warning
The following build warning have been reported:
arch/powerpc/kvm/book3s_hv_rmhandlers.o: warning: objtool: .text+0xe84: intra_function_call not a direct call
arch/powerpc/kernel/switch.o: warning: objtool: .text+0x4: intra_function_call not a direct call
This happens due to commit bb7f054f4de2 ("objtool/powerpc: Add support
for decoding all types of uncond branches") because that commit decodes
'bl .+4' as a normal instruction because that instruction is used by
clang instead of 'bcl 20,31,+.4' for relocatable code.
The solution is simply to remove the ANNOTATE_INTRA_FUNCTION_CALL
annotation now that the instruction is not seen as a function call
anymore.

powerpc: merge 32-bit and 64-bit _switch implementation
The _switch stack frame setup are substantially the same, so are the
comments. The difference in how the stack and current are switched,
and other hardware and software housekeeping is done is moved into
macros.
Generated code should be unchanged.
