Roland McGrath 114f515777 kbuild: use LDFLAGS_MODULE only for .ko links
Sam Ravnborg pointed out that Documentation/kbuild/makefiles.txt already
says this is what it's for.  This patch makes the reality live up to the
documentation.  This fixes the problem of LDFLAGS_BUILD_ID getting into too
many places.

Roland McGrath 18991197b4 Use --build-id ld option
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.

Sam Ravnborg 741f98fe29 kbuild: do section mismatch check on full vmlinux
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).

Linus Torvalds b46522394d Revert "[PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+"
This reverts commit c8fdd24725.

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.

Sam Ravnborg c53aeca059 kbuild: complain about missing system calls
Most system calls seems to get added to i386 first. This patch
automatically generates a warning for any new system call which is
implemented on i386 but not the architecture currently being compiled.
On PowerPC at the moment, for example, it results in these warnings:
init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented
init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented
init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented

The file scripts/checksyscalls.sh list a number of legacy system calls
that are ignored because they only makes sense on i386 systems.

Other contributors to this patch are Russell King <rmk+lkml@arm.linux.org.uk>
and Stéphane Jourdois <kwisatz@rubis.org>

Andi Kleen c8fdd24725 [PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+
The kernel only supports gcc 3.2+ now so it doesn't make sense
anymore to explicitely check for options this compiler version
already has.

This actually fixes a bug. The -mprefered-stack-boundary check
never worked because gcc rightly complains

  CC      arch/i386/kernel/asm-offsets.s
cc1: -mpreferred-stack-boundary=2 is not between 4 and 12

We just never saw the error because of cc-options.
I changed it to 4 to actually work.

Tested by compiling i386 and x86-64 defconfig with gcc 3.2.

Should speed up the build time a tiny bit and improve
stack usage on i386 slightly.

created at the end of the build: it's either not present or, worse, wrong for
most of the build.

So the patch arranges for compile.h to be built at the start of the build
process.  It also consolidates the compile.h rules with those for version.h
and utsname.h, so they all get built together.

I hope.  My chances of having got this right are about 2%.

Jan Beulich 690a973f48 [PATCH] x86-64: Speed up dwarf2 unwinder
This changes the dwarf2 unwinder to do a binary search for CIEs
instead of a linear work. The linker is unfortunately not
able to build a proper lookup table at link time, instead it creates
one at runtime as soon as the bootmem allocator is usable (so you'll continue
using the linear lookup for the first [hopefully] few calls).
The code should be ready to utilize a build-time created table once
a fixed linker becomes available.

David Gibson 18e39913d4 [PATCH] Fix spurious error on TAGS target when missing defconfig
Not all architectures have a file named 'defconfig' (e.g.  powerpc).
However the make TAGS and make tags targets search such files for tags,
causing an error message when they don't exist.  This patch addresses the
problem by instructing xargs not to run the tags program if there are no
matching files.

David Woodhouse 1ab7a1f3b4 [PATCH] headers_check: use a different default directory
`make headers_check' wants to go and write stuff in /lib/modules, which
requires root, whic is unfortunate.

In fact, there's no _particular_ reason for headers_install to put it there
either -- it can go into a subdirectory of the build tree in both cases.
It's not intended to go directly into /usr/include, which is why we didn't
put it there -- and we certainly don't want people screwing around with
symlinking to it.  It's for distributors to take away and do stuff with, so
leaving it in $(objtree) is fine, even in the headers_install case.

I picked $(objtree)/usr/include but I have no _particular_ preference
for that; it just seemed reasonable.
