modpost: Fix address calculation in reloc_location()
This patch fixes a segfault in modpost that is observed when the gold
linker is used to link the input objects.
The problem is that reloc_location (modpost.c) is computing the
address of the relocation target incorrectly. Here, elf->hdr points
to the beginning of the ELF file in memory, sechdr points to the
relocation section header, section is the index of the section
being relocated, and sechdrs[section].sh_offset would be the offset
of that section, relative to the beginning of the ELF file. Adding
elf->hdr + sechdrs[section].sh_offset gives you the address of the
beginning of the section, and adding r->r_offset to that gives you the
address of the location to be relocated. You do not need to subtract
sechdrs[section].sh_addr from that -- the result of this is an address
outside the file, and causes the segfault when addend_386_rel tries to
dereference it.
This bug is not observed when GNU ld is used to link the inputs. The
object file ubuntu/omnibook/omnibook.o is the result of an ld -r of
several other files. When GNU ld does an ld -r, it sets the vaddr
field for each section to 0, but gold lays out the section addresses
sequentially instead:
Section Headers:
[Nr] Name Type Addr Off Size ES Flg Lk Inf Al
[ 0] NULL
00000000 000000 000000 00 0 0 0
[ 1] .text PROGBITS
00000000 000034 004794 00 AX 0 0 4
[ 2] .data PROGBITS
0000b9d0 0047c8 0009c0 00 WA 0 0 4
[ 3] .bss NOBITS
000162f8 005188 00013c 00 WA 0 0 4
[ 4] .rodata.str1.1 PROGBITS
00004f2d 0052c4 001b1a 01 AMS 0 0 1
[ 5] .init.text PROGBITS
00004794 006dde 0005fa 00 AX 0 0 1
[ 6] .exit.text PROGBITS
00004d8e 0073d8 00018a 00 AX 0 0 1
...
So the bug in the tool remained undiscovered because the section's vaddr
always happened to be 0.

Instead of creating the debian package for the compiling userland,
create it for a userland matching the kernel thats being compiled.
This patch supports all Lenny release architectures,
and Linux-based architecture candidates for Squeeze.
If it can't find a proper Debian userspace it displays a warning,
and fallback to let deb-gencontrol use the host's userspace arch.
Eg. with this patch the following make command:
make ARCH=i386 deb-pkg
will output an i386 Debian package instead of an amd64 one,
when run on an amd64 machine.

The patch here fixes this by moving the capabilities checks out of the

Fix gcc 4.5.1 miscompiling drivers/char/i8k.c (again)
The fix in commit
6b4e81db2552 ("i8k: Tell gcc that *regs gets
clobbered") to work around the gcc miscompiling i8k.c to add "+m
(*regs)" caused register pressure problems and a build failure.
Changing the 'asm' statement to 'asm volatile' instead should prevent
that and works around the gcc bug as well, so we can remove the "+m".
[ Background on the gcc bug: a memory clobber fails to mark the function
the asm resides in as non-pure (aka "__attribute__((const))"), so if
the function does nothing else that triggers the non-pure logic, gcc
will think that that function has no side effects at all. As a result,
callers will be mis-compiled.
Adding the "+m" made gcc see that it's not a pure function, and so
does "asm volatile". The problem was never really the need to mark
"*regs" as changed, since the memory clobber did that part - the
problem was just a bug in the gcc "pure" function analysis - Linus ]

GFS2: Fix inode deallocation race
This area of the code has always been a bit delicate due to the
subtleties of lock ordering. The problem is that for "normal"
alloc/dealloc, we always grab the inode locks first and the rgrp lock
later.
In order to ensure no races in looking up the unlinked, but still
allocated inodes, we need to hold the rgrp lock when we do the lookup,
which means that we can't take the inode glock.
The solution is to borrow the technique already used by NFS to solve
what is essentially the same problem (given an inode number, look up
the inode carefully, checking that it really is in the expected
state).
We cannot do that directly from the allocation code (lock ordering
again) so we give the job to the pre-existing delete workqueue and
carry on with the allocation as normal.
If we find there is no space, we do a journal flush (required anyway
if space from a deallocation is to be released) which should block
against the pending deallocations, so we should always get the space
back.
