Better dwarf2 unwind information is a good thing, it allows better debugging with kgdb and crash and helps systemtap. Commit 00308649 ("Build with -fno-dwarf2-cfi-asm") disabled some CFI information globally to work around a module loader bug on powerpc. But this disables the better unwind tables for all architectures, not just powerpc. Move the workaround to powerpc and also add a suitable comment that's it really a workaround. This improves dwarf2 unwind tables on x86 at least.

The LOCALVERSION= string passed to "make" will now always be appended to the kernel version after CONFIG_LOCALVERSION, if it exists, regardless of whether CONFIG_LOCALVERSION_AUTO is set or not. This allows users to uniquely identify their kernel builds with a string. If CONFIG_LOCALVERSION_AUTO is enabled, the unique SCM tag reported by setlocalversion (or .scmversion) is appended to the kernel version, if it exists. When CONFIG_LOCALVERSION_AUTO is not enabled, a `+' is appended to the kernel version to represent that the kernel has been revised since the last release unless "make LOCALVERSION=" was used to uniquely identify the build. The end result is this: - when LOCALVERSION= is passed to "make", it is appended to the kernel version, - when CONFIG_LOCALVERSION_AUTO is enabled, a unique SCM identifier is appended if the respository has been revised beyond a tagged commit, and - when CONFIG_LOCALVERSION_AUTO is disabled, a `+' is appended if the repository has been revised beyond a tagged commit and LOCALVERSION= was not passed to "make". Examples: With CONFIG_LOCALVERSION_AUTO: "make" results in v2.6.32-rc4-00149-ga3ccf63e. If there are uncommited changes to the respository, it results in v2.6.32-rc4-00149-ga3ccf63e-dirty. If "make LOCALVERSION=kbuild" were used, it results in v2.6.32-rc4-kbuild-00149-ga3ccf63e-dirty. Without CONFIG_LOCALVERSION_AUTO, "make" results in v2.6.32-rc4+ unless the repository is at the Linux v2.6.32-rc4 commit (in which case the version would be v2.6.32-rc4). If "make LOCALVERSION=kbuild" were used, it results in v2.6.32-rc4-kbuild. Also renames variables such as localver-auto and _localver-auto to more accurately describe what they represent: localver-extra and scm-identifier, respectively.

This adds CROSS_COMPILE as a kconfig string so you can store it in .config. Then you can use plain "make" in the configured kernel build directory to do the right cross compilation without setting the command-line or environment variable every time. With this, you can set up different build directories for different kernel configurations, whether native or cross-builds, and then use the simple: make -C /build/dir M=module-source-dir idiom to build modules for any given target kernel, indicating which one by nothing but the build directory chosen. I tried a version that defaults the string with env="CROSS_COMPILE" so that in a "make oldconfig" with CROSS_COMPILE in the environment you can just hit return to store the way you're building it. But the kconfig prompt for strings doesn't give you any way to say you want an empty string instead of the default, so I punted that.

Setting LC_CTYPE=C breaks localized messages in some setups. With only LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not so defined character classes and tolower()/toupper(). The former is not a big issue, because we can assume that e.g. [:alpha:] will always include a-zA-Z and we only ever process ASCII input. The latter seems only affect arch/sh/tools/gen-mach-types, which we can handle separately. So after this patch the meaning of ranges like [a-z], the behavior of sort and join, etc. should be the same everywhere and at the same time gcc should be able to print localized waring and error messages. LC_NUMERIC=C might not be necessary, but setting it doesn't hurt. Reported-by: NSimon Horman <horms@verge.net.au> Reported-by: NSergei Trofimovich <slyfox@inbox.ru> Acked-by: NH.

There are a number of common Unix constructs like character ranges in grep/sed/awk which don't work as expected with LC_COLLATE set to other than C. Similarly, set LC_CTYPE and LC_NUMERIC to C to avoid other nasty surprises. In order to make sure these actually take effect we also have to clear LC_ALL. Signed-off-by: NH.

To make it easier for module-init-tools and scripts like mkinitrd to distinguish builtin and missing modules, install a modules.builtin file listing all builtin modules. This is done by generating an additional config file (tristate.conf) with tristate options set to uppercase 'Y' or 'M'. If we source that config file, the builtin modules appear in obj-Y.

We no longer use this directory for generated files and all architectures has moved their header files so no symlink tricks are needed either. Drop the symlink and drop the ARCH check. If we really need to check that the SRCARCH has not changed when we build a kernel we can add this check back - but then we will find a more convenient way to store the info.

The simplest method was to add an extra asm-offsets.h file in arch/$ARCH/include/asm that references the generated file. We can now migrate the architectures one-by-one to reference the generated file direct - and when done we can delete the temporary arch/$ARCH/include/asm/asm-offsets.h file.

The namespace used in arch/$ARCH/include is different from what is used in include/ except for the include/asm directory. This patch gives the arch/$ARCH/include/asm directory priority over include/asm. When we add asm-offsets.h to arch/$ARCH/include/asm/ this patch makes sure we pick up the arch specific version and not the one we have in include/asm. The situation with an asm-offsets.h file located in both include/asm _and_ arch/$ARCH/include/asm will happen when we move more files over to include/generated. This happens because in some cases it is not practical to rename all users so we simply add a file in arch/$ARCH/include/asm that includes the generated version. This is the solution we use for asm-offsets.h as an example. Signed-off-by: NSam Ravnborg <sam@ravnborg.org> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: NMichal Marek <mmarek@suse.cz>

If the user has an older version of objcopy, that can not handle converting local symbols to global and vice versa, then some functions will not be part of the dynamic function tracer. The current code in recordmcount.pl will print a warning in this case. Unfortunately, there exists lots of files that may have this issue with older objcopys and this will cause a warning for every file compiled with this issue. This patch solves this overwhelming output by creating a .tmp_quiet_recordmcount file on the first instance the warning is encountered. The warning will not print if this file exists. The temp file is deleted at the beginning of the compile to ensure that the warning will happen once again on new compiles (because the issue is still present).

Revert commit 57554334 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] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.
