Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__.
Since these are kernel only headers, we don't need #ifdef __KERNEL__
so can simplify things a bit.

If an architecture wants to use jump labels in assembly, it
will still need to define a macro to create the __jump_table
entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h
for an example).

* [PATCH 2/3] jump_label: Allow jump labels to be used in assembly

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.

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.

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 ("powerpc/jump_label: Use HAVE_JUMP_LABEL")

I assume it's best for Andrew to take this series with all the cross-archness?

cheers

jump_label: Allow asm/jump_label.h to be included in assembly

Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__.
Since these are kernel only headers, we don't need #ifdef
__KERNEL__ so can simplify things a bit.

If an architecture wants to use jump labels in assembly, it
will still need to define a macro to create the __jump_table
entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h
for an example).

jump_label: Allow jump labels to be used in assembly

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.

powerpc, jump_label: Include linux/jump_label.h to get HAVE_JUMP_LABEL define

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.

Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__.
Since these are kernel only headers, we don't need #ifdef __KERNEL__
so can simplify things a bit.

If an architecture wants to use jump labels in assembly, it
will still need to define a macro to create the __jump_table
entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h
for an example).

Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__.
Since these are kernel only headers, we don't need #ifdef __KERNEL__
so can simplify things a bit.

If an architecture wants to use jump labels in assembly, it
will still need to define a macro to create the __jump_table
entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h
for an example).

Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__.
Since these are kernel only headers, we don't need #ifdef __KERNEL__
so can simplify things a bit.

If an architecture wants to use jump labels in assembly, it
will still need to define a macro to create the __jump_table
entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h
for an example).
