Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove a
duplicate of ARRAY_SIZE. Some trailing whitespaces are also removed.drivers/block/acsi* has been left out as it's marked BROKEN.

Since version 4.1 the gcc is warning about ignored attributes. This patch is
using the equivalent attribute on the struct instead of on each of the
structure or union members.GCC Manual:
"Specifying Attributes of Typespacked
This attribute, attached to struct or union type definition, specifies
that
each member of the structure or union is placed to minimize the memory
required. When attached to an enum definition, it indicates that the
smallest integral type should be used.Specifying this attribute for struct and union types is equivalent to
specifying the packed attribute on each of the structure or union
members."Signed-off-by: Jan Blunck

Earlier fix removed unused phase, but that changed the values for other
phases. Since these are exposed to userspace through ppdev, it is safer
not to change them. Restore the unused phase value.Signed-off-by: Marko Kohtala

- handle failures when create_workqueue and kthread_create are called

If a 9pfs server crashes, v9fs_fd_close() is called. Subsequently, in
cleaning up by performing a umount() on the FS that was provided by this
server v9fs_fd_close() is called again, and uses the old, freed valus of
trans->priv. This patch ensures that trans->priv can be freed only once,
otherwise this function bails early.Signed-off-by: Michal Ostrowski

Reorder members of the kiocb structure to make sync kiocb setup faster. By
setting the elements sequentially, the write combining buffers on the CPU
are able to combine the writes into a single burst, which results in fewer
cache cycles being consumed, freeing them up for other code. This results
in a 10-20KB/s[*] increase on the bw_unix part of LMbench on my test
system.* The improvement varies based on what other patches are in the system,
as there are a number of bottlenecks, so this number is not absolutely
accurate.Signed-off-by: Benjamin LaHaise

Add a hook so architectures can validate /dev/mem mmap requests.
This is analogous to validation we already perform in the read/write
paths.The identity mapping scheme used on ia64 requires that each 16MB or
64MB granule be accessed with exactly one attribute (write-back or
uncacheable). This avoids "attribute aliasing", which can cause a
machine check.Sample problem scenario:
- Machine supports VGA, so it has uncacheable (UC) MMIO at 640K-768K
- efi_memmap_init() discards any write-back (WB) memory in the first granule
- Application (e.g., "hwinfo") mmaps /dev/mem, offset 0
- hwinfo receives UC mapping (the default, since memmap says "no WB here")
- Machine check abort (on chipsets that don't support UC access to WB
memory, e.g., sx1000)In the scenario above, the only choices are
- Use WB for hwinfo mmap. Can't do this because it causes attribute
aliasing with the UC mapping for the VGA MMIO space.
- Use UC for hwinfo mmap. Can't do this because the chipset may not
support UC for that region.
- Disallow the hwinfo mmap with -EINVAL. That's what this patch does.Signed-off-by: Bjorn Helgaas

There's one scsi driver which doesn't compile due to weird __VA_ARGS__ tricks
and the rather useful scsi/sd.c is currently getting an ICE. None of the new
SAS code compiles, due to extensive use of anonymous unions. The V4L guys are
very good at exploiting the gcc-2.95.x macro expansion bug (_why_ does each
driver need to implement its own debug macros?) and various people keep on
sneaking in anonymous unions, which are rather nice.Plus anonymous unions are rather useful.

I couldn't find any docs explaining the contents of /sys/block//stat,
so I wrote up the following. I'm not completely sure it's accurate - Jens,
could you give a yea or nay on this?In particular, the counts of read/write IOs and read/write sectors are
incremented in different places - it looks like they both increment as the
request is being finished, but I'm not completely sure of that.Cc: Jens Axboe
