Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

sparc64: Add __arch64__ to CHECKFLAGS Otherwise sparse doesn't work. The 32 vs. 64 header ifdef used under arch/sparc/include/asm/ is: #if defined(__sparc__) && defined(__arch64__) And that doesn't work for sparse unless we give it __arch64__ Signed-off-by: David S. Miller <davem@davemloft.net>

sparc: add -m64 when building vmlinux.lds David Miller noticed that the build of vmlinux.lds failed to use the -m64 specifier. This caused the build to break with a bi-arch gcc with unified headers. Add the -m64 option to CPPFLAGS_vmlinux.lds so we have the correct defines available when building vmliux.lds. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

# Undefine sparc when processing vmlinux.lds - it is used
# And teach CPP we are doing 64 bit builds (for this case)

[SPARC64]: Remove Makefile code for ancient gcc and binutils. The kernel hasn't supported the compilers which need these tests for years. Signed-off-by: David S. Miller <davem@davemloft.net>

[SPARC64]: Add -mtune=ultrasparc3 if possible. This gives better heuristics for the cost of a multiply (fixed 5 cycles), rather than the 'ultrasparc' setting (variable, and unpredictable if the second argument is non-constant).

kbuild: enable 'make CFLAGS=...' to add additional options to CC The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.
