Make sure we keep page->mapping NULL on the pages we're getting
via alloc_page. It gets set so a few of the callbacks can do the right
thing, but in general these pages don't have a mapping.
Don't try to truncate compressed inline items in btrfs_drop_extents.
The whole compressed item must be preserved.
Don't try to create multipage inline compressed items. When we try to
overwrite just the first page of the file, we would have to read in and recow
all the pages after it in the same compressed inline items. For now, only
create single page inline items.
Make sure we lock pages in the correct order during delalloc. The
search into the state tree for delalloc bytes can return bytes before
the page we already have locked.

The digital mic wasn't detected properly for ALC269 auto-probing mode
because of its widget number. Fixed now.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
The recent addition of automatic mic-muting is broken in some cases.
The code assumes that the pin nids <= 0x18, but the digital pins can
be less than 0x18.
Also, it assumes the front-mic being the internal mic, but it depends
on the hardware implementation actually.
Instead of complex case-fixes, better to disable the code as now.

Updated the patch to address comments by Michael Ellerman.
Specifically, changed upper limit in for loop to
ARRAY_SIZE() macro and added a check to make sure the
number of events specified by the user, which is used as
the max for indexing various arrays, is no bigger then the
declared size of the arrays.
The size of the pm_signal_local array should be equal to the
number of SPUs being configured in the array. Currently, the
array is of size 4 (NR_PHYS_CTRS) but being indexed by a for
loop from 0 to 7 (NUM_SPUS_PER_NODE).

commit ed95d7450d ("powerpc: Update

A patch has already been submitted to dtc/libfdt mainline. We don't

Impact: optimize/clean-up the IO mapping implementation of the i915 DRM driver
Switch the i915 device aperture mapping to the io-mapping interface, taking
advantage of the cleaner API to extend it across all of the mapping uses,
including both pwrite and relocation updates.
This dramatically improves performance on 64-bit kernels which were using

Impact: add new generic io_map_*() APIs
Graphics devices have large PCI apertures which would consume a significant
fraction of a 32-bit address space if mapped during driver initialization.
Using ioremap at runtime is impractical as it is too slow.
This new set of interfaces uses atomic mappings on 32-bit processors and a
large static mapping on 64-bit processors to provide reasonable 32-bit
performance and optimal 64-bit performance.
The current implementation sits atop the io_map_atomic fixmap-based
mechanism for 32-bit processors.

Impact: save kernel .text by loosening kexec page alignment
This patch removes PAGE_SIZE alignment from relocate_kernel(). Before
kexec jump patches are merged, control page is mapped to
relocate_kernel in kexec page tables, so relocate_kernel must be
PAGE_SIZE aligned. Now, control page is mapped to identity mapped
address, so relocate_kernel need not to be PAGE_SIZE aligned any
more. This can reduce a few KB from kernel text segement.
