#     powerpc: Handle .text.{hot,unlikely}.* in linker script
#     
#     Commit eff8728fe698 ("vmlinux.lds.h: Add PGO and AutoFDO input
#     sections") added ".text.unlikely.*" and ".text.hot.*" due to an LLVM
#     change [1].
#     
#     After another LLVM change [2], these sections are seen in some PowerPC
#     builds, where there is a orphan section warning then build failure:
#     
#     $ make -skj"$(nproc)" \
#            ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- LLVM=1 O=out \
#            distclean powernv_defconfig zImage.epapr
#     ld.lld: warning: kernel/built-in.a(panic.o):(.text.unlikely.) is being placed in '.text.unlikely.'
#     ...
#     ld.lld: warning: address (0xc000000000009314) of section .text is not a multiple of alignment (256)
#     ...
#     ERROR: start_text address is c000000000009400, should be c000000000008000
#     ERROR: try to enable LD_HEAD_STUB_CATCH config option
#     ERROR: see comments in arch/powerpc/tools/head_check.sh
#     ...
#     
#     Explicitly handle these sections like in the main linker script so
#     there is no more build failure.
