check_partition() stops its probe once it hits an I/O error from the
partition checkers. This would prevent the actual partition checker
getting a chance to verify the partition.
So this patch lets check_partition() continue probing untill it hits a
success while recording the I/O error which might have been reported by the
checking routines.
Also, it does some cleanup of the partition methods for ibm, atari and
amiga to return -1 upon hitting an I/O error.

The current rescan_partition implementation ignores the errors that comes from
the lower layer. It reports success for unknown partitions as well as I/O
error cases while reading the partition information.
The unknown partition is not (and will not be) considered as an error in the
kernel, since there are legal users of it (e.g, members of a RAID5 MD Device
or a new disk which is not partitioned at all ). Changing this behaviour
would scare the user about a serious problem with their disk and is not
recommended. Thus for both "unknown partitions" to the Linux (eg., DEC
VMS,Novell Netware) and the legal users of NULL partition, would still be
reported as "SUCCESS".
The patch attached here, scares the user about something which he does need to
worry about. i.e, returning -EIO on disk I/O errors while reading the
partition information.

Replace all uses of kmem_cache_t with struct kmem_cache.
The patch was generated using the following script:
#!/bin/sh
#
# Replace one string by another in all the kernel sources.
#
set -e
for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
quilt add $file
sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
mv /tmp/$$ $file
quilt refresh
done
The script was run like this
sh replace kmem_cache_t "struct kmem_cache"

Currently a user process cannot rise its own oom_adj value (i.e.
unprotecting itself from the OOM killer). As this value is stored in the
task structure it gets inherited and the unprivileged childs will be unable
to rise it.
The EPERM will be handled by the generic proc fs layer, as only processes
with the proper caps or the owner of the process will be able to write to
the file. So we allow only the processes with CAP_SYS_RESOURCE to lower
the value, otherwise it will get an EACCES which seems more appropriate
than EPERM.

OpenVZ Linux kernel team has found a problem with mounting in compat mode.
Simple command "mount -t smbfs ..." on Fedora Core 5 distro in 32-bit mode
leads to oops:
Unable to handle kernel NULL pointer dereference at 0000000000000000 RIP: compat_sys_mount+0xd6/0x290
Process mount (pid: 14656, veid=300, threadinfo ffff810034d30000, task ffff810034c86bc0)
Call Trace: ia32_sysret+0x0/0xa
The problem is that data_page pointer can be NULL, so we should skip data
conversion in this case.

This patch adds SPU elf notes to the coredump. It creates a separate note
for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1,
/signal1_type, /signal2, /signal2_type, /event_mask, /event_status,
/mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id.
A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to
specify they have extra elf core notes.
A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the
additional notes could be calculated and added to the notes phdr entry.
A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes
would be written after the existing notes.
The SPU coredump code resides in spufs. Stub functions are provided in the
kernel which are hooked into the spufs code which does the actual work via
register_arch_coredump_calls().
A new set of __spufs_<file>_read/get() functions was provided to allow the
coredump code to read from the spufs files without having to lock the
SPU context for each file read from.

Instead we record our state on the allocation context structure which all
