This patchset enables and implements objtool --mcount
option on powerpc. This applies atop powerpc/merge branch.
Changelog:
----
v5:
* Patch 02/16 - Add Reviewed-by tag from Christophe Leroy
* Patch 03/16 - Fix merge conflicts with latest powerpc/merge branch
* Patch 06/16 - Files arch/powerpc/kernel/cpu_setup_fsl_booke.S and
arch/powerpc/kernel/head_fsl_booke.S are not present
today. Removed annotations in those assembly files.
* Patch 11/16 - Add Reviewed-by tag from Christophe Leroy
- Changed scripts/Makefile.lib file to make
CONFIG_HAVE_OBJTOOL_NOP_MCOUNT depend on
CONFIG_FTRACE_MCOUNT_USE_OBJTOOL.
* Patch 12/16 - Add Reviewed-by tag from Christophe Leroy
* Patch 16/16 - Add Reviewed-by tag from Christophe Leroy
* For this series - Add Acked-by tag from Josh Poimboeuf
- Add Tested-by tag from Naveen N. Rao
- Add Reviewed-by tag from Naveen N. Rao
----
v4:
* Patch 11/16 - Introduce a new config option
CONFIG_HAVE_OBJTOOL_NOP_MCOUNT as a means for
architectures to enable nop'ing ftrace locations.
- Remove Acked-by tag from Peter Zijlstra (Intel),
and Reviewed-by tag from Christophe Leroy.
[This is done because I reworked the patch to add
a new config option to objtool. Please let me know
if you want me to retain the tags. Thanks!]
* Patch 16/16 - Rework the patch to handle only 'bl' instruction
decoding.

* [PATCH v5 01/16] powerpc: Fix __WARN_FLAGS() for use with Objtool

Commit 1e688dd2a3d675 ("powerpc/bug: Provide better flexibility to
WARN_ON/__WARN_FLAGS() with asm goto") updated __WARN_FLAGS() to use asm
goto, and added a call to 'unreachable()' after the asm goto for optimal
code generation. With CONFIG_OBJTOOL enabled, 'annotate_unreachable()'
statement in 'unreachable()' tries to note down the location of the
subsequent instruction in a separate elf section to aid code flow
analysis. However, on powerpc, this results in gcc emitting a call to a
symbol of size 0. This results in objtool complaining of "unannotated
intra-function call" since the target symbol is not a valid function
call destination.
Objtool wants this annotation for code flow analysis, which we are not
yet enabling on powerpc. As such, expand the call to 'unreachable()' in
__WARN_FLAGS() without annotate_unreachable():
barrier_before_unreachable();
__builtin_unreachable();
This still results in optimal code generation for __WARN_FLAGS(), while
getting rid of the objtool warning.
We still need barrier_before_unreachable() to work around gcc bugs 82365
and 106751:

* [PATCH v5 02/16] powerpc: Override __ALIGN and __ALIGN_STR macros

In a subsequent patch, we would want to annotate powerpc assembly functions
with SYM_FUNC_START_LOCAL macro. This macro depends on __ALIGN macro.
The default expansion of __ALIGN macro is:
#define __ALIGN .align 4,0x90
So, override __ALIGN and __ALIGN_STR macros to use the same alignment as
that of the existing _GLOBAL macro. Also, do not pad with 0x90, because
repeated 0x90s are not a nop or trap on powerpc.

that of the existing _GLOBAL macro. Also, do not pad with 0x90, because
repeated 0x90s are not a nop or trap on powerpc.

Objtool throws unannotated intra-function call warnings in the following
assembly files:
arch/powerpc/kernel/vector.o: warning: objtool: .text+0x53c: unannotated intra-function call
arch/powerpc/kvm/book3s_hv_rmhandlers.o: warning: objtool: .text+0x60: unannotated intra-function call

arch/powerpc/kvm/book3s_hv_interrupts.o: warning: objtool: .text+0x6c: unannotated intra-function call
arch/powerpc/kernel/misc_64.o: warning: objtool: .text+0x64: unannotated intra-function call
Objtool does not add STT_NOTYPE symbols with size 0 to the rbtree, which
is why find_call_destination() function is not able to find the
destination symbol for 'bl' instruction. For such symbols, objtool is
throwing unannotated intra-function call warnings in assembly files. Fix
these warnings by annotating those symbols with SYM_FUNC_START_LOCAL and
SYM_FUNC_END macros, inorder to set symbol type to STT_FUNC and symbol
size accordingly.

Objtool does not add STT_NOTYPE symbols with size 0 to the rbtree, which
is why find_call_destination() function is not able to find the
destination symbol for 'bl' instruction. For such symbols, objtool is
throwing unannotated intra-function call warnings in assembly files. Fix
these warnings by annotating those symbols with SYM_FUNC_START_LOCAL and
SYM_FUNC_END macros, inorder to set symbol type to STT_FUNC and symbol
size accordingly.

objtool throws the following unannotated intra-function call warnings:
arch/powerpc/kernel/entry_64.o: warning: objtool: .text+0x4: unannotated intra-function call
arch/powerpc/kvm/book3s_hv_rmhandlers.o: warning: objtool: .text+0xe64: unannotated intra-function call
arch/powerpc/kvm/book3s_hv_rmhandlers.o: warning: objtool: .text+0xee4: unannotated intra-function call
Fix these warnings by annotating intra-function calls, using
ANNOTATE_INTRA_FUNCTION_CALL macro, to indicate that the branch targets
are valid.

* [PATCH v5 05/16] powerpc: Skip objtool from running on drivers/crypto/vmx/aesp8-ppc.o

With objtool enabled, below warnings are seen when trying to build:
drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: aes_p8_set_encrypt_key+0x44: unannotated intra-function call
drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: .text+0x2448: unannotated intra-function call
drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: .text+0x2d68: unannotated intra-function call
Skip objtool from running on drivers/crypto/vmx/aesp8-ppc.o file for the
following reasons:
- Since this file comes from OpenSSL, and since it is a perl file which
generates a .S file, it may not be the best choice to make too many
code changes to such files, unless absolutely necessary.
- As far as the objtool --mcount functionality is concerned, we do not
have to run objtool on this file because there are no calls to
_mcount.

[Sathvika Vasireddy: Changed subject line from "objtool/powerpc: Activate
objtool on PPC32" to "powerpc: Fix objtool unannotated intra-function call
warnings on PPC32", and removed Kconfig change to enable objtool, as it
is a part of "objtool/powerpc: Enable objtool to be built on ppc" patch in
this series.]

* [PATCH v5 09/16] objtool: Use target file endianness instead of a compiled constant

From: Christophe Leroy <christophe.leroy@csgroup.eu>
Some architectures like powerpc support both endianness, it's
therefore not possible to fix the endianness via arch/endianness.h
because there is no easy way to get the target endianness at
build time.
Use the endianness recorded in the file objtool is working on.

* [PATCH v5 09/16] objtool: Use target file endianness instead of a compiled constant

naveen.n.rao, mbenes, chenzhongjin
From: Christophe Leroy <christophe.leroy@csgroup.eu>
Some architectures like powerpc support both endianness, it's
therefore not possible to fix the endianness via arch/endianness.h
because there is no easy way to get the target endianness at
build time.
Use the endianness recorded in the file objtool is working on.

In order to allow using objtool on cross-built kernels,
determine size of long from elf data instead of using
sizeof(long) at build time.

Some architectures (powerpc) may not support ftrace locations being nop'ed
out at build time. Introduce CONFIG_HAVE_OBJTOOL_NOP_MCOUNT for objtool, as
a means for architectures to enable nop'ing of ftrace locations. Add --mnop
as an option to objtool --mcount, to indicate support for the same.
Also, make sure that --mnop can be passed as an option to objtool only when
--mcount is passed.

According to objdump it's:

Please also look at the version that's in tip/x86/core (and next). This
stuff should be gone now.
include/linux/linkage.h now reads like:
#ifndef __ALIGN
#define __ALIGN .balign CONFIG_FUNCTION_ALIGNMENT
#define __ALIGN_STR __stringify(__ALIGN)
#endif

Since the above mentioned changes are not a part of powerpc/merge branch
yet, I am retaining this patch for this merge cycle and will post a
cleanup patch (to move to using FUNCTION_ALIGNMENT_4B) after the next -rc1.
