When unbinding and rebinding the driver on a system with a card in PHB0, this
error condition is reached after a few attempts:

contexts currently using the AFU.

commit id 9975f5e added new config variable CONFIG_KVM_BOOK3S_HV_POSSIBLE
that helps to select the relevant code in the kernel when HV and PR

By using lower part of swapper_pg_dir as load index to r11, we can remove the
ori instruction.

SERMR (System Error Mask Register), to actually get and clear the status

Commit 1bc9e47aa8e4 ("powerpc/jump_label: Use HAVE_JUMP_LABEL")
converted uses of CONFIG_JUMP_LABEL to HAVE_JUMP_LABEL in
some assembly files.
HAVE_JUMP_LABEL is defined in linux/jump_label.h, so we need to
include this or we always get the non jump label fallback code.
Fixes: 1bc9e47aa8e4 ("powe
To use jump labels in assembly we need the HAVE_JUMP_LABEL define,
so we select a fallback version if the toolchain does not support
them.
Modify linux/jump_label.h so it can be included by assembly files.
We also need to add -DCC_HAVE_ASM_GOTO to KBUILD_AFLAGS.
