* 'hostprogs-wmissing-prototypes' of git://git.kernel.org/pub/scm/linux/kernel/git/josh/linux-misc:
Makefile: Add -Wmising-prototypes to HOSTCFLAGS
oss: Mark loadhex static in hex2hex.c
dtc: Mark various internal functions static
dtc: Set "noinput" in the lexer to avoid an unused function
drm: radeon: Mark several functions static in mkregtable
arch/sparc/boot/*.c: Mark various internal functions static
arch/powerpc/boot/addRamDisk.c: Mark several internal functions static
arch/alpha/boot/tools/objstrip.c: Mark "usage" static
Documentation/vm/page-types.c: Declare checked_open static
genksyms: Mark is_reserved_word static
kconfig: Mark various internal functions static
kconfig: Make zconf.y work with current bison
|
|
Now that all host programs use static for all private functions and
forward prototypes for all extern functions, add -Wmissing-prototypes to
HOSTCFLAGS in the hopes of keeping it that way.
All versions of GCC supported by the kernel handle -Wmissing-prototypes.

Revert commit 575543347b5baed0ca927cb90ba8807396fe9cc9
It caused following issues:
- On architectures where ARCH= setting is used to select between
32 and 64 bit this was no longer possible without "make mrproper"
- If ARCH was changed then kbuild refused to run "make mrproper"
because ARCH had changed
- When CROSS_COMPILE was changed people were asked to run "make mrproper"
but kbuild refused to run "make mrproper" because CROSS_COMPILE changed.
- Spaces in CROSS_COMPILE was not 'supported'
- If an non-existing ARCH= was used kbuild could get stuck
Lessons learned:
. Despite being simple and straghtforward people uses very different
approaches when building the kernel.
. CROSS_COMPILE is sometimes used for ccache despite cache being
only a CC frontend so one would have expected CC to be
used for this purpose.
. And obviously this was not tested widely enough.

I'm skipping -rc2 because the -rc1 Makefile mistakenly said -rc2, so in
order to avoid confusion, I'm jumping from -rc1 to -rc3. That way, when
'uname' (or an oops report) says 2.6.32-rc2, there's no confusion about
whether people perhaps meant -rc1 or -rc2.

Albin Tonnerre <albin.tonnerre@free-electrons.com> reported:
Bash 4 filters out variables which contain a dot in them.
This happends to be the case of CPPFLAGS_vmlinux.lds.
This is rather unfortunate, as it now causes
build failures when using SHELL=/bin/bash to compile,
or when bash happens to be used by make (eg when it's /bin/sh)
Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.
This is also nice cleanup as we move the information out where
it is used.
Notes for the different architectures touched:
arm - we use an already exported symbol
cris - we use a config symbol aleady available
[Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
Added a few variables to CPPFLAGS - they are only used by
the linker script.
[Not build tested]
powerpc - removed assignment that is not needed
[not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation
[not build tested]

The upcomming gcc 4.5 has a new -fconserve-stack option that tells the
inliner to take stack frame size in account. Set it if the compiler
supports it.

The new alternative `gold' linker in recent binutils doesn't support
the -X option. This breaks allyesconfig builds that have
CONFIG_STRIP_ASM_SYMS enabled. Check if the linker really supports
the option using ld-option.
