a combination call of kmalloc() and copy_from_user() is replaced by
memdup_user(). So btrfs_ioctl_resize() doesn't use GFP_NOFS any more.

These debugging WARN_ONs make too much console noise during regular
IO failures. An IO failure will still generate a number of messages
as we verify checksums etc, but these two are not needed.

When a btrfs metadata read fails, the first thing we try to do is find
a good copy on another mirror of the block. If this fails, read_tree_block()
ends up returning a buffer that isn't up to date.
The btrfs btree reading code was reworked to drop locks and repeat
the search when IO was done, but the changes didn't add a check for failed
reads. The end result was looping forever on buffers that were never
going to become up to date.

This flag is used to decide when we need to send a given file through

This reverts commit a425a638c858fd10370b573bde81df3ba500e271.
Now that the previous commit removed the "readpage" actor for hugetlb
files, read-ahead will no longer mess up the mapping, and there's no
longer any reason to treat hugetlbfs mappings specially.

The core VM assumes the page size used by the address_space in
inode->i_mapping is PAGE_SIZE but hugetlbfs breaks this assumption by
inserting pages into the page cache at offsets the core VM considers
unexpected.
This would not be a problem except that hugetlbfs also provide a
->readpage implementation. As it exists, the core VM can assume the
base page size is being used, allocate pages on behalf of the
filesystem, insert them into the page cache and call ->readpage to
populate them. These pages are the wrong size and at the wrong offset
for hugetlbfs causing confusion.
This patch deletes the ->readpage implementation for hugetlbfs on the
grounds the core VM should not be allocating and populating pages on
behalf of hugetlbfs. There should be no existing users of the
->readpage implementation so it should not cause a regression.

Squashfs is broken on any system where the page size is larger than
the metadata size (8192). This is easily fixed by ensuring cache->pages
is always > 0.

ioatdma 0000:00:08.0: DMA-API: device driver frees DMA memory with
wrong function [device address=0x000000007f76f800] [size=2000 bytes]
[map
ped as single] [unmapped as page]
The ioatdma driver was unmapping all regions
(either allocated as page or single) using unmap_page.
This patch lets dma driver recognize if unmap_single or unmap_page should be used.
It introduces two new dma control flags:
DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE.
They should be set to indicate dma driver to do dma-unmapping as single
(first one for the source, tha latter for the destination).
If respective flag is not set, the driver assumes dma-unmapping as page.

Fix resembles implementation from Marc Gauthier and Piet Denaly:
In the Xtensa architecture, assembly generates literals which must always
precede the code (the L32R instruction that loads them only uses negative
PC-relative offsets). For any *.text section, literals are placed in a
corresponding *.literal section. The linker script (vmlinux.lds) must
place these in the correct order. It must also combine them, when the
*.text section can be larger than L32R's 256 kB range.
For example, this doesn't work: *(.literal) *(.text) because L32R
instructions at the end of .text can't reach the literals.
The linker can solve this if they are combined in parentheses, like this:
*(.literal .text)
because it is now allowed mix literals in .text to bring them in range.
None of this is done by standard vmlinux.lds.h macros such as TEXT_TEXT
and INIT_TEXT. To avoid replicating the logic of that header file, we
instead post-process the generated linker script to convert *(xxx.text)
to *(xxx.literal xxx.text) for the following text sections:
.text .ref.text .*init.text .*exit.text .text.*
using a sed script. To do this we must override the default rule for
vmlinux.lds (see scripts/Makefile.build and the top-level Makefile)
to insert this extra step.

Commit '28a0ce7 xtensa: use correct stack pointer for stack traces'
changed the stack tracer from always reading the stack pointer
register to always using the saved value in the task descriptor.
The author was too dense to consider the fact that the saved stack
value is stale for a running process und thus unusable for 'current'.
What we do now is to use the stack pointer register (a1) for when the
task is unknown - we can't help it then - or when the task is
'current'. For everything else use the saved stack pointer value
contained in the task descriptor.
