6d5aefb8ea WorkQueue: Fix up arch-specific work items where possible
Fix up arch-specific work items where possible to use the new work_struct and
delayed_work structs.

Three places that enqueue bits of their stack and then return have been marked
with #error as this is not permitted.

e62438630c [PATCH] Centralise definitions of sector_t and blkcnt_t
CONFIG_LBD and CONFIG_LSF are spread into asm/types.h for no particularly
good reason.

Centralising the definition in linux/types.h means that arch maintainers
don't need to bother adding it, as well as fixing the problem with
x86-64 users being asked to make a decision that has absolutely no
effect.

The H8/300 porters seem particularly confused since I'm not aware of any
microcontrollers that need to support 2TB filesystems.

bf1ab978be [POWERPC] coredump: Add SPU elf notes to coredump.
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.

800b399669 [PATCH] libata: always use polling IDENTIFY
libata switched to IRQ-driven IDENTIFY when IRQ-driven PIO was
introduced.  This has caused a lot of problems including device
misdetection and phantom device.

ATA_FLAG_DETECT_POLLING was added recently to selectively use polling
IDENTIFY on problemetic drivers but many controllers and devices are
affected by this problem and trying to adding ATA_FLAG_DETECT_POLLING
for each such case is diffcult and not very rewarding.

This patch makes libata always use polling IDENTIFY.  This is
consistent with libata's original behavior and drivers/ide's behavior.

3d3cca3755 [PATCH] libata: implement ATA_FLAG_SETXFER_POLLING and use it in pata_via, take #2
This patch implements ATA_FLAG_SETXFER_POLLING and use in pata_via.
If this flag is set, transfer mode setting performed by polling not by
interrupt.  This should help those controllers which raise interrupt
before the command is actually complete on SETXFER.

Rationale for this approach.

* uses existing facility and relatively simple
* no busy sleep in the interrupt handler
* updating drivers is easy

While at it, kill now unused flag ATA_FLAG_SRST in pata_via.

582982e699 [PATCH] libata: remove unused HSM_ST_UNKNOWN
HSM_ST_UNKNOWN is not used anywhere.  Its value is zero and supposed
to serve sanity check purpose but HSM_ST_IDLE is used for that
purpose.  This unused state causes confusion.  After a port is
initialized but before the first command is executed, the idle hsm
state is UNKNOWN.  However, once a command has completed, the idle hsm
state is IDLE.  This defeats sanity check in ata_pio_task() for the
first command.

This patch removes HSM_ST_UNKNOWN and consequently make HSM_ST_IDLE
the default state.

1b683b5512 [NETFILTER]: sip conntrack: better NAT handling
The NAT handling of the SIP helper has a few problems:

- Request headers are only mangled in the reply direction, From/To headers
  not at all, which can lead to authentication failures with DNAT in case
  the authentication domain is the IP address

- Contact headers in responses are only mangled for REGISTER responses

- Headers may be mangled even though they contain addresses not
  participating in the connection, like alternative addresses

- Packets are droppen when domain names are used where the helper expects
  IP addresses

This patch takes a different approach, instead of fixed rules what field
to mangle to what content, it adds symetric mapping of From/To/Via/Contact
headers, which allows to deal properly with echoed addresses in responses
and foreign addresses not belonging to the connection.

So I think we're safe in turning hh_len an u16, end result:

e3703b3de1 [RTNETLINK]: Add rtnl_put_cacheinfo() to unify some code
IPv4, IPv6, and DECNet all use struct rta_cacheinfo in a similiar
way, therefore rtnl_put_cacheinfo() is added to reuse code.
