The variable CPPFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.This patch replace use of CPPFLAGS with KBUILD_CPPFLAGS all over the
tree and enabling one to use:
make CPPFLAGS=...
to specify additional CPP commandline options.Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390Signed-off-by: Sam Ravnborg

The previous patches was preparation.
With this patch we can now say:
make CFLAGS=-Os vmlinuxAnd the option specified will be appended to the
options passed to gcc for C files.For assembler use:
make AFLAGS=-foo vmlinux

Change the invocations of make in the output directory Makefile and the
main Makefile for separate object trees to pass all goals to one $(MAKE)
via a new phony target "sub-make" and the existing target _all.When compiling with separate object directories, a separate make is called
in the context of another directory (from the output directory the main
Makefile is called, the Makefile is then restarted with current directory
set to the object tree). Before this patch, when multiple make command
goals are specified, each target results in a separate make invocation.
With make -j, these invocations may run in parallel, resulting in multiple
commands running in the same directory clobbering each others results.I did not try to address make -j for mixed dot-config and no-dot-config
targets. Because the order does matter, a solution was not obvious.
Perhaps a simple check for MAKEFLAGS having -j and refusing to run would
be appropriate.Signed-off-by: Milton Miller

The assembler for a while now supports -gdwarf to generate source line info
just like the C compiler does. Source-level assembly debugging sounds like an
oxymoron, but it is handy to be able to see the right source file and read its
comments rather than just the disassembly. This patch enables -gdwarf for
assembly files when CONFIG_DEBUG_INFO=y and the assembler supports the option.Signed-off-by: Roland McGrath

Jan Engelhardt reported:
You can cause a recursion in kbuild/make with the following:make O=$PWD kernel/time.o
make mrproperOf course no one would use O=$PWD (that's just the testcase),
but this happened too often:/ws/linux/linux-2.6.23$ make O=/ws/linux/linux-2.6.23 kernel/time.o
(Oops - should have been O=/ws/linux/obj-2.6.23!)Fixed by an explicit test for this case - we error
out if output directory and source directory are the same.Tested-by: Jan Engelhardt

This change passes the --build-id when linking the kernel and when linking
modules, if ld supports it. This is a new GNU ld option that synthesizes an
ELF note section inside the read-only data. The note in this section contains
unique identifying bits called the "build ID", which are generated so as to be
different for any two linked ELF files that aren't identical. The build ID
can be recovered from stripped files, memory dumps, etc. and used to look up
the original program built, locate debuginfo or other details or history
associated with it. For normal program linking, the compiler passes
--build-id to ld by default, but the option is needed when using ld directly
as we do.Signed-off-by: Roland McGrath

Previously we did do the check on the .o files used to link
vmlinux but that failed to find questionable references across
the .o files.
Create a dedicated vmlinux.o file used only for section mismatch checks
that uses the defualt linker script so section does not get renamed.The vmlinux.o may later be used as part of the the final link of vmlinux
but for now it is used fo section mismatch only.
For a defconfig build this is instant but for an allyesconfig this
add two minutes to a full build (that anyways takes ~2 hours).Signed-off-by: Sam Ravnborg

This reverts commit c8fdd247255a3a027cd9f66dcf93e6847d1d2f85.
It turns out the kernel was correct, and the gcc complaint was a gcc
bug. The preferred stack boundary is expressed not in bytes, but in the
the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2"
is in fact exactly what we want, but a gcc that is compiled for x86-64
will consider it an error (because the 64-bit calling sequence says that
the stack should be 16-byte aligned) even if we are then using "-m32" to
generate 32-bit code.Noted-by: Mikulas Patocka
