db8c1a7b2c kbuild: fix building external modules
kbuild failed to locate Makefile for external modules.
This brought to my attention how the variables for directories
have different values in different usage scenarios.

Different kbuild usage scenarios:
make       - plain make in same directory where kernel source lives
make O=    - kbuild is told to store output files in another directory
make M=    - building an external module
make O= M= - building an external module with kernel output seperate from src

Value assigned to the different variables:

           |$(src)          |$(obj) |$(srctree)        |$(objtree)
make       |reldir to k src |as src |abs path to k src |abs path to k src
make O=    |reldir to k src |as src |abs path to k src |abs path to output dir
make M=    |abs path to src |as src |abs path to k src |abs path to k src
make O= M= |abs path to src |as src |abs path to k src |abs path to k output

path to kbuild file:

make       | $(srctree)/$(src), $(src)
make O=    | $(srctree)/$(src)
make M=    | $(src)
make O= M= | $(src)

From the table above it can be seen that the only good way to find the
home directory of the kbuild file is to locate the one of the two variants
that is an absolute path. If $(src) is an absolute path (starts with /)
then use it, otherwise prefix $(src) with $(srctree).

72ba47c1b2 kbuild: silence mystery message
During last phase of the build the following message were displayed:
/bin/sh: +@: command not found

This message appears due to slightly changed semantics
of cmd and if_changed_rule.
The easy fix was to insert a dummy command first in rule_ksym_ld.
The alternative was to redo part of this processing in the top-level
Makefile - a volatile area that I try to avoid.

From: Ryan Anderson <ryan@michonline.com>

Make the deb-pkg build target understand the "um" arch and set up the
package and directory structure to match a mainline-Debian style
user-mode-linux package.

This is primarily so that it stops matching, exactly, the naming
convention used by normal, non-UML kernels generated by this command.

Installing "linux-2.6.11" and "linux-2.6.11", where one is a UML kernel
doesn't do the right thing.  This fixes that.

d80e224609 kbuild: Don't fail if include/asm symlink exists
From: Andreas Gruenbacher <agruen@suse.de>

We're having the following situation: There are user-space applications
that include kernel headers directly. With a completely unconfigured
/usr/src/linux tree, including most headers fails because essential
files are not there:

	include/asm
	include/linux/autoconf.h
	include/linux/version.h

So we create these files. On the other hand, we want to use
/usr/src/linux as read-only source for building kernels or additional
modules. Now when building a kernel with a separate output directory
(O=), there is a check in the main makefile for the include/asm symlink.
There is no real need for this check: if we ensure that
$(objdir)/include/asm is always created as the patch does,
$(srctree)/include/asm becomes irrelevant.

6d30e3a899 kbuild: Avoid inconsistent kallsyms data
Several reports on inconsistent kallsyms data has been caused by the aliased symbols
__sched_text_start and __down to shift places in the output of nm.
The root cause was that on second pass ld aligned __sched_text_start to a 4 byte boundary
which is the function alignment on i386.
sched.text and spinlock.text is now aligned to an 8 byte boundary to make sure they
are aligned to a function alignemnt on most (all?) archs.

a0674e88d9 [PATCH] kbuild: allow cscope to index multiple architectures
I have a single source tree which I cross compile for a couple of
different architectures using ARHC=foo O=blah etc.

The existing cscope target is very handy but only indexes the current
$(ARCH), which is a pain since inevitably I'm interested in the other
one at any given time ;-). This patch allows me to pass a list of
architectures for cscope to index. e.g.
	make ALLSOURCE_ARCHS="i386 arm" cscope

This change also works for etags etc, and I presume it is just as useful
there.

acbef459a6 [PATCH] kbuild: make 'cscope -q' play well with cscope.el
I tried the Linux Makefile 'make cscope' target, and found that the
generated database is not compatible with 'cscope.el' under XEmacs.
The thing is that 'cscope.el' does not allow setting the command line
options to the 'cscope' commands it runs, and it errors with a message
about the options not matching the ones used to generate the index.

It turns out the cscope designers already thought of this.  The
options can be written into the "cscope.files".  The included patch
moves the "-q" and "-k" options from the 'cmd_cscope' to the
'cmd_cscope-file', echoing them into the top of the files listing.

Now the index is generated with the "-q" option, and when 'cscope.el'
performs it's search, it uses that argument as well.  Lookups are fast
and everyone is happy.

b95d4fec89 [PATCH] kbuild: modpost needs to cope with new glibc elf header on sparc
Recently a change in the glibc elf.h header has been introduced causing
modpost to spawn tons of warnings (like the one below) building the kernel
on sparc:

[SNIP]
*** Warning: "current_thread_info_reg" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined!
*** Warning: "" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined!
*** Warning: "" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined!
[SNIP]

Ben Collins discovered that the STT_REGISTERED definition in glibc did change
and that this change needs to be propagated to modpost.

glibc change:
-#define STT_REGISTER   13              /* Global register reserved to app. */
+#define STT_SPARC_REGISTER     13      /* Global register reserved to app. */

I did and tested this simple patch to maintain compatibility with newer (>= 2.3.4)
and older (<= 2.3.2) glibc.

3b5cc09033 [IA64] assign_irq_vector() should not panic
Current assign_irq_vector() will panic if interrupt vectors is running
out. But I think how to handle the case of lack of interrupt vectors
should be handled by the caller of this function. For example, some
PCI devices can raise the interrupt signal via both MSI and I/O
APIC. So even if the driver for these device fails to allocate a
vector for MSI, the driver still has a chance to use I/O APIC based
interrupt. But currently there is no chance for these driver to use
I/O APIC based interrupt because kernel will panic when
assign_irq_vector() fails to allocate interrupt vector.

The following patch changes assign_irq_vector() for ia64 to return
-ENOSPC on error instead of panic (as i386 and x86_64 versions do).
