linux-toradex.git/arch/sparc/Makefile, branch v3.9.2

Merge branch 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2012-05-22T02:43:57+00:00

Pull smp hotplug cleanups from Thomas Gleixner:
 "This series is merily a cleanup of code copied around in arch/* and
  not changing any of the real cpu hotplug horrors yet.  I wish I'd had
  something more substantial for 3.5, but I underestimated the lurking
  horror..."

Fix up trivial conflicts in arch/{arm,sparc,x86}/Kconfig and
arch/sparc/include/asm/thread_info_32.h

sparc: introduce arch/sparc/Kbuild

2012-05-15T20:18:08+00:00

This allows us to do:

    make arch/sparc/

to build the core part of the sparc kernel.

sparc32: Build kernel with -mcpu=v8

2012-05-15T17:48:54+00:00

With Cypress gone we can generate real hardware integer multiply
and divide instructions at will.

sparc32: Pass -mcpu=v7 explicitly to gcc.

2012-05-12T22:16:45+00:00

We should be agnostic to what gcc happens to be generating by default.

sparc32: Add -Av8 to assembler command line.

2012-03-14T01:19:51+00:00

Newer version of binutils are more strict about specifying the
correct options to enable certain classes of instructions.

The sparc32 build is done for v7 in order to support sun4c systems
which lack hardware integer multiply and divide instructions.

So we have to pass -Av8 when building the assembler routines that
use these instructions and get patched into the kernel when we find
out that we have a v8 capable cpu.

sparc32: added U-Boot build target: uImage

sparc: Set UTS_MACHINE correctly.

2009-12-06T01:17:55+00:00

"ARCH" can be just about anything, so we shouldn't end up
with UTS_MACHINE of "sparc" in a 64-bit kernel build just
because someone set the personality using 'sparc32' or
similar.  CONFIG_SPARC64 drives the compilation and
therefore provides the definitive value, not "ARCH".

This mirrors commit 8c6531f7a99f29ba8817ffb12cc9ecf190049bd6
(x86: correctly set UTS_MACHINE for "make ARCH=x86")
