Since we have the fixed pin-port mapping for Intel IronLake (IbexPeak)
and Baytrail (ValleyView) platforms in the code side, now it's time to
add the support in the codec driver side. This patch simply enables
the i915 ELD notifier for these in addition with the fix of the
mapping from the port to NID in the callback.Signed-off-by: Takashi Iwai
-
Intel IronLake and ValleyView platforms have different HDMI widget pin
and digital port mapping from other newer ones. The recent ones
(HSW+) have NID 0x05 to 0x07 for port B to port D, while these chips
have NID 0x04 to 0x06.For adapting this mapping, pass the codec object instead of the bus
object to snd_hdac_sync_audio_rate() and snd_hdac_acomp_get_eld() so
that they can check the codec ID and calculate the mapping properly.The changes in the HDMI codec driver side will follow in the later
patch.Signed-off-by: Takashi Iwai
-
Intel SandyBridge and IvyBridge (CougarPoint and PantherPoint
platforms) have also the same digital port vs audio widget mapping
(from port B = NID 0x05 to port D = NID 0x07) as Haswell & co.
So, we can reuse the existing functions for HSW+ for these platforms
without changing there, but just by re-adding the on-demand i915
binding in HDMI codec driver.Signed-off-by: Takashi Iwai
-
For reducing the splat of is_haswell_plus() or such macros, this patch
introduces pin_cvt_fixup() ops to hdmi_spec. For HSW+ and VLV+
codecs, set this ops so that the driver can call the Intel-specific
workarounds appropriately.A gratis bonus that we can remove the mux_id argument from
hdmi_choose_cvt(), too, since the fixup function always refers the
mux_idx from the given per_pin object.Signed-off-by: Takashi Iwai
-
Instead of checking at each time with is_haswell_plus() macro,
override the setup_stream ops itself for HSW+ chips.Signed-off-by: Takashi Iwai
-
The need for reprogramming the AMP mute bit at each audio info frame
setup isn't always specific to Intel chips. It's safer to set it
generically for all codecs with the amp bit, as this verb execution
itself isn't too much load. This eliminates one usage of
is_haswell_plus() macro, after all.Signed-off-by: Takashi Iwai
-
We have too many Intel-specific codes in patch_hdmi_generic() despite
its function name. And this makes it difficult to adjust per chipset,
e.g. for allowing the audio notifier on an old chipset, one would need
to add an explicit if() check.This patch attempts some code refactoring and cleanups in this regard;
the Intel-specific codes are moved out of patch_generic_hdmi() into
the new functions, patch_i915_hsw_hdmi() and patch_i915_byt_hdmi(),
depending on the chipset. The other old Intel chipsets keep using
patch_generic_hdmi() without Intel hacks. The existing
patch_generic_hdmi() is also split to a few components so that they
can be called from the Intel codec parsers.There are still many is_haswell*() and is_valleyview*() macro usages
in the code. They will be cleaned up later. For the time being, only
the entry are concerned.Along with this change, the i915_bound flag and the on-demand i915
component binding have been removed as a cleanup, since there is no
user at this moment. This will be added back later once when Cougar
Point and else start using the i915 eld notifier.Signed-off-by: Takashi Iwai

Pull orangefs filesystem from Mike Marshall.
This finally merges the long-pending orangefs filesystem, which has been
much cleaned up with input from Al Viro over the last six months. From
the documentation file:"OrangeFS is an LGPL userspace scale-out parallel storage system. It
is ideal for large storage problems faced by HPC, BigData, Streaming
Video, Genomics, Bioinformatics.Orangefs, originally called PVFS, was first developed in 1993 by Walt
Ligon and Eric Blumer as a parallel file system for Parallel Virtual
Machine (PVM) as part of a NASA grant to study the I/O patterns of
parallel programs.Orangefs features include:
- Distributes file data among multiple file servers
- Supports simultaneous access by multiple clients
- Stores file data and metadata on servers using local file system
and access methods
- Userspace implementation is easy to install and maintain
- Direct MPI support
- Stateless"see Documentation/filesystems/orangefs.txt for more in-depth details.

Commit 0b81d07790726 ("fs crypto: move per-file encryption from f2fs
tree to fs/crypto") moved the f2fs crypto files to fs/crypto/ and
renamed the symbol prefixes from "f2fs_" to "fscrypt_" (and from "F2FS_"
to just "FS" for preprocessor symbols).Because of the symbol renaming, it's a bit hard to see it as a file
move: usegit show -M30 0b81d07790726
to lower the rename detection to just 30% similarity and make git show
the files as renamed (the header file won't be shown as a rename even
then - since all it contains is symbol definitions, it looks almost
completely different).Even with the renames showing as renames, the diffs are not all that
easy to read, since so much is just the renames. But Eric Biggers
noticed that it's not just all renames: the initialization of the
xts_tweak had been broken too, using the inode number rather than the
page offset.That's not right - it makes the xfs_tweak the same for all pages of each
inode. It _might_ make sense to make the xfs_tweak contain both the
offset _and_ the inode number, but not just the inode number.Reported-by: Eric Biggers

If
- generic_file_read_iter() gets called with a zero read length,
- the read offset is at a page boundary,
- IOCB_DIRECT is not set
- and the page in question hasn't made it into the page cache yet,
then do_generic_file_read() will trigger a readahead with a req_size hint
of zero.Since roundup_pow_of_two(0) is undefined, UBSAN reports
UBSAN: Undefined behaviour in include/linux/log2.h:63:13
shift exponent 64 is too large for 64-bit type 'long unsigned int'
CPU: 3 PID: 1017 Comm: sa1 Tainted: G L 4.5.0-next-20160318+ #14

The net effect is that the initial readahead size is arch dependent for
requested read lengths of zero: for example, since1UL << (sizeof(unsigned long) * 8)
evaluates to 1 on x86 while its result is 0 on ARMv7, the initial readahead
size becomes 4 on the former and 0 on the latter.What's more, whether or not the file access timestamp is updated for zero
length reads is decided differently for the two cases of IOCB_DIRECT
being set or cleared: in the first case, generic_file_read_iter()
explicitly skips updating that timestamp while in the latter case, it is
always updated through the call to do_generic_file_read().According to POSIX, zero length reads "do not modify the last data access
timestamp" and thus, the IOCB_DIRECT behaviour is POSIXly correct.Let generic_file_read_iter() unconditionally check the requested read
length at its entry and return immediately with success if it is zero.Signed-off-by: Nicolai Stange

Implement the stack depot and provide CONFIG_STACKDEPOT. Stack depot
will allow KASAN store allocation/deallocation stack traces for memory
chunks. The stack traces are stored in a hash table and referenced by
handles which reside in the kasan_alloc_meta and kasan_free_meta
structures in the allocated memory chunks.IRQ stack traces are cut below the IRQ entry point to avoid unnecessary
duplication.Right now stackdepot support is only enabled in SLAB allocator. Once
KASAN features in SLAB are on par with those in SLUB we can switch SLUB
to stackdepot as well, thus removing the dependency on SLUB stack
bookkeeping, which wastes a lot of memory.This patch is based on the "mm: kasan: stack depots" patch originally
prepared by Dmitry Chernenkov.Joonsoo has said that he plans to reuse the stackdepot code for the
mm/page_owner.c debugging facility.[akpm@linux-foundation.org: s/depot_stack_handle/depot_stack_handle_t]

This lets us strip everything below the IRQ entry point to reduce the
number of unique stack traces needed to be stored.Move the definition of __irq_entry to so that the
