ARM: exynos: defconfig update

This turns on a number of configs that are useful on the Chromebook, but also
good to have on in general:

* USB host and MMC drivers(!)
* I2C GPIO arbitration driver
* CYAPA trackpad driver
* simplefb
* CROS EC and keyboard drivers
* S5M8767 driver

* MAX8997 driver
* DEVTMPFS + mount
* DM_CRYPT (as module)
* CRYPTOLOOP
* HIGHMEM
* PRINTK timestamps

This also turns off DEBUG_LL, and switches the hardcoded Samsung lowlevel
uart to uart 3 (which is only used to show the "uncompressing kernel"
message at boot, it seems).

Pull btrfs fixes from Chris Mason:
 "Miao Xie has been very busy, fixing races and enospc problems and many
  other small but important pieces.

  Alexandre Oliva discovered some problems with how our error handling
  was interacting with the block layer and for now has disabled our
  partial handling of sub-page writes.  The real sub-page work is in a
  series of patches from IBM that we still need to integrate and test.
  The code Alexandre has turned off was really incomplete.

  Josef has more error handling fixes and an important fix for the new
  skinny extent format.

  This also has my fix for the tracepoint crash from late in 3.9.  It's
  the first stage in a larger clean up to get rid of btrfs_bio and make
  a proper bioset for all the items we need to tack into the bio.  For
  now the bioset only holds our mirror_num and stripe_index, but for the
  next merge window I'll shuffle more in."

Merge branch 'devm_no_resource_check' of git://git./linux/kernel/git/wsa/linux

Pull devm usage cleanup from Wolfram Sang:
 "Lately, I have been experimenting how to improve the devm interface to
  make writing device drivers easier and less error prone while also
  getting rid of its subtle issues.  I think it has more potential but
  still needs work and definately conistency, especiall in its usage.

  The first thing I come up with is a low hanging fruit regarding
  devm_ioremap_resouce().  This function already checks if the passed
  resource is valid and gives an error message if not.  So, we can
  remove similar checks from the drivers and get rid of a bit of code
  and a number of inconsistent error strings.

  This series only removes the unneeded check iff devm_ioremap_resource
  follows platform_get_resource directly.  The previous version tried to
  shuffle code if needed, too, what lead to an embarrasing bug.  It
  turned out to me that shuffling code for all cases found will make the
  automated script too complex, so I am unsure if an automated cleanup
  is the proper tool for this case.  Removing the easy stuff seems
  worthwhile to me, though.

  Despite various architectures and platform dependencies, I managed to
  compile test 45 out of 57 modified files locally using heuristics and
  defconfigs."

Btrfs: use a btrfs bioset instead of abusing bio internals

Btrfs has been pointer tagging bi_private and using bi_bdev
to store the stripe index and mirror number of failed IOs.

As bios bubble back up through the call chain, we use these
to decide if and how to retry our IOs.  They are also used
to count IO failures on a per device basis.

Recently a bio tracepoint was added lead to crashes because
we were abusing bi_bdev.

This commit adds a btrfs bioset, and creates explicit fields
for the mirror number and stripe index.  The plan is to
extend this structure for all of the fields currently in
struct btrfs_bio, which will mean one less kmalloc in
our IO path.

11 years agobtrfs: do away with non-whole_page extent I/O

btrfs: do away with non-whole_page extent I/O

end_bio_extent_readpage computes whole_page based on bv_offset and
bv_len, without taking into account that blk_update_request may modify
them when some of the blocks to be read into a page produce a read
error.  This would cause the read to unlock only part of the file
range associated with the page, which would in turn leave the entire
page locked, which would not only keep the process blocked instead of
returning -EIO to it, but also prevent any further access to the file.

It turns out that btrfs always issues whole-page reads and writes.
The special handling of non-whole_page appears to be a mistake or a
left-over from a time when this wasn't the case.  Indeed,
end_bio_extent_writepage distinguished between whole_page and
non-whole_page writes but behaved identically in both cases!

I've replaced the whole_page computations with warnings, just to be
sure that we're not issuing partial page reads or writes.  The
warnings should probably just go away some time.
