d960c9ce47 x86 setup: remove IMAGE_OFFSET
After commit 968de4f ("i386: Relocatable kernel support") IMAGE_OFFSET wasn't
actually used anymore in the (current) X86 build system. Now remove its last
traces.

d2f37384fc x86: when building image.iso, use isohybrid if it exists
When building image.iso (make isoimage), use the isohybrid tool if it
exists.  isohybrid is a script included with Syslinux 3.72 and higher,
which creates an image that can be booted either as a hard disk
(including removable, e.g. USB disk) or as a CD-ROM.

If isohybrid doesn't exist, then this has no effect.

e44b7b7525 x86: move suspend wakeup code to C
Move wakeup code to .c, so that video mode setting code can be shared
between boot and wakeup. Remove nasty assembly code in 64-bit case by
re-using trampoline code. Stack setup was fixed to clear high 16bits
of %esp, maybe that fixes some machines.

.c code sharing and morse code was done H. Peter Anvin, Sam Ravnborg
reviewed kbuild related stuff, and it seems okay to him. Rafael did
some cleanups.

[rjw:
* Made the patch stop breaking compilation on x86-32
* Added arch/x86/kernel/acpi/sleep.h
* Got rid of compiler warnings in arch/x86/kernel/acpi/sleep.c
* Fixed 32-bit compilation on x86-64 systems
* Added include/asm-x86/trampoline.h and fixed the non-SMP
  compilation on 64-bit x86
* Removed arch/x86/kernel/acpi/sleep_32.c which was not used
* Fixed some breakage caused by the integration of smpboot.c done
  under us in the meantime]

f0be6c6a69 x86 setup: print missing CPU features in cleartext
Instead of obscure numbers, print the list of missing CPU features in
cleartext.  To conserve space, use a host program (mkcpustr.c) to
produce a compact list of mandatory features only.

1622ac23bd x86: define OBJCOPYFLAGS explicitly for each target.
Do this rather than defining a global version and overriding it in
almost all cases in order to make subsequent patches simpler.

a6b68076fd x86: compile apm and voyager module only when selected in Kconfig
Previously the complete files were #ifdef'ed, but now handle that in the
Makefile.

May save a minor bit of compilation time.

4ba7e5cd49 x86: biarch support for 32 bit builds beautified
There were no reason to mess around with CC, AS and LD.
Fixing this up avoided duplicated option for ld.

A small fixlet were needed in boot/Makefile which assumed
that CC were modified.

d746d647f3 x86: do not use $(ARCH) when not needed
For x86 ARCH may say i386 or x86_64 and soon x86.
Rely on CONFIG_X64_32 to select between 32/64 or just
hardcode the value as appropriate.

7eebb93486 x86: fix boot error introduced by kbuild
x86 uses target specific assignment of EXTRA_AFLAGS,
EXTRA_CFLAGS - this caused troubles with
introducing asflags-y, ccflags-y.

Fixed the target specific assignments in arch/x86/boot/Makefile
and auditted the rest of the kernel for similar usage.

222d394d30 kbuild: enable 'make AFLAGS=...' to add additional options to AS
The variable AFLAGS 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 AFLAGS with KBUILD_AFLAGS all over
the tree.

Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390

a0f97e06a4 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.
