Since this macro is identical to pgprot_writecombine() and is only used
in a single place, remove it completely to avoid confusion. On ARMv7+
processors, the coherent DMA mapping must be Normal NonCacheable (a.k.a.
writecombine) to avoid mismatched hardware attribute aliases (with the
kernel linear mapping as Normal Cacheable).

The current dma_ops do not specify an mmap function so maping
falls back to the default implementation. There are at least
two issues with using the default implementation:
1) The pgprot is always pgprot_noncached (strongly ordered)
memory even with coherent operations
2) dma_common_mmap calls virt_to_page on the remapped non-coherent
address which leads to invalid memory being mapped.
Fix both these issue by implementing a custom mmap function which
correctly accounts for remapped addresses and sets vm_pg_prot
appropriately.

We can get false negative from __lookup_mnt() if an unrelated vfsmount
gets moved. In that case legitimize_mnt() is guaranteed to fail,
and we will fall back to non-RCU walk... unless we end up running
into a hard error on a filesystem object we wouldn't have reached
if not for that false negative. IOW, delaying that check until
the end of pathname resolution is wrong - we should recheck right
after we attempt to cross the mountpoint. We don't need to recheck
unless we see d_mountpoint() being true - in that case even if
we have just raced with mount/umount, we can simply go on as if
we'd come at the moment when the sucker wasn't a mountpoint; if we
run into a hard error as the result, it was a legitimate outcome.
__lookup_mnt() returning NULL is different in that respect, since
it might've happened due to operation on completely unrelated
mountpoint.

In all callchains leading to prepend_name(), the value left in *buflen
is eventually discarded unused if prepend_name() has returned a negative.

Commit bd2a31d522 ("get rid of fget_light()") introduced the
__fdget_pos() function, which returns the resulting file pointer and
fdput flags combined in an 'unsigned long'. However, it also changed the
behavior to return files with FMODE_PATH set, which shouldn't happen
because read(), write(), lseek(), etc. aren't allowed on such files.
This commit restores the old behavior.
This regression actually had no effect on read() and write() since
FMODE_READ and FMODE_WRITE are not set on file descriptors opened with
O_PATH, but it did cause lseek() on a file descriptor opened with O_PATH
to fail with ESPIPE rather than EBADF.

Use table based setup to register the controls and DAPM widgets and routes.
This on one hand makes the code a bit cleaner and on the other hand
the board level DAPM elements get registered in the card's DAPM context rather
than in the CODEC's DAPM context.
The mfld_machine driver is a bit special in that it directly writes to one of
the CODEC registers from one of the control handlers. Previous to this patch it
was able to get a pointer to the CODEC from the control, since the control was
registered with the CODEC. This won't be possible anymore once the control is
registered with the card. Since there are already global variables in the driver
accessed in the same function the patch adds a global variable that holds a
pointer to the CODEC and uses that.

I've been working on USB for seven years at Intel, and it's time for a
change of pace. I'm pleased to announce that I'll be joining the Intel
OTC ChromeOS team, where I'll get to learn and play with everything
across the entire Linux stack, from kernel to graphics to browser
technologies. (I'm a secret adventure/indie/casual gamer, so I'm super
excited to start working on graphics features for ChromeOS.)
I'm leaving the xHCI driver in Mathias Nyman's capable hands. I'll
still be around to answer any architectural questions or triage really
tough bugs, but I expect to ramp down on xHCI driver work in the coming
weeks.
I'll be available to answer xHCI questions until I start my 8-week
sabbatical on May 8th. I'll be doing a National Parks road trip, and
it's unlikely I'll have cell coverage. And, let's face it, people are
supposed to ignore work email on sabbaticals. :)
After my sabbatical ends on July 7th, I'll be focusing my time fully on
ChromeOS. It's been great working with and learning from Greg, Alan,
Oliver, and Felipe, but it's time to move onto my next adventure.
So long, and thanks for all the fishes!

xhci: Maintainership change for 3.15.
I've been working on USB for seven years at Intel, and it's time for a
change of pace. I'm pleased to announce that I'll be joining the Intel
OTC ChromeOS team, where I'll get to learn and play with everything
across the entire Linux stack, from kernel to graphics to browser
technologies. (I'm a secret adventure/indie/casual gamer, so I'm super
excited to start working on graphics features for ChromeOS.)
I'm leaving the xHCI driver in Mathias Nyman's capable hands. I'll
still be around to answer any architectural questions or triage really
tough bugs, but I expect to ramp down on xHCI driver work in the coming
weeks.
I'll be available to answer xHCI questions until I start my 8-week
sabbatical on May 8th. I'll be doing a National Parks road trip, and
it's unlikely I'll have cell coverage. And, let's face it, people are
supposed to ignore work email on sabbaticals. :)
After my sabbatical ends on July 7th, I'll be focusing my time fully on
ChromeOS. It's been great working with and learning from Greg, Alan,
Oliver, and Felipe, but it's time to move onto my next adventure.
So long, and thanks for all the fishes!

This regulator is used for system IO and is fixed to 1.8V. Let's give
consumers the option to fetch the voltage level.
