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).

[PATCH] kbuild: make 'cscope -q' play well with cscope.el
I tried the Linux Makefile 'make cscope' target, and found that the

The thing is that 'cscope.el' does not allow setting the command line

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.
[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

on sparc:
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).

[IPV4]: multicast API "join" issues
This patch corrects a few problems with the IP_ADD_MEMBERSHIP
socket option:
1) The existing code makes an attempt at reference counting joins when
using the ip_mreqn/imr_ifindex interface. Joining the same group
on the same socket is an error, whatever the API. This leads to
unexpected results when mixing ip_mreqn by index with ip_mreqn by
address, ip_mreq, or other API's. For example, ip_mreq followed by
ip_mreqn of the same group will "work" while the same two reversed
will not.
Fixed to always return EADDRINUSE on a duplicate join and
removed the (now unused) reference count in ip_mc_socklist.
2) The group-search list in ip_mc_join_group() is comparing a full
ip_mreqn structure and all of it must match for it to find the
group. This doesn't correctly match a group that was joined with
ip_mreq or ip_mreqn with an address (with or without an index). It
also doesn't match groups that are joined by different addresses on
the same interface. All of these are the same multicast group,
which is identified by group address and interface index.
Fixed the check to correctly match groups so we don't get
duplicate group entries on the ip_mc_socklist.
3) The old code allocates a multicast address before searching for
duplicates requiring it to free in various error cases. This
patch moves the allocate until after the search and
igmp_max_memberships check, so never a need to allocate, then free
an entry.
