For normal request mmc_blk_issue_rq is called twice with asynchronous
transfer(cur and prev). Host's claim and release can be done in each
mmc_blk_issue_rq. However, Special request is currently excluded in
asynchronous transfer. After special request is finished, if there is
no new request, mmc_release_host won't be called in mmc_blk_issue_rq.
The problem is founded during mmc_suspend.

All users of the sdhci_ops struct in the sdhci core already treat it as
const. The sdhci-pltfm code itself never actually looks at the ops field
of the sdhci_pltfm_data struct and merely passes it on to the sdhci core,
so make we can make it const in the sdhci_pltfm_data struct as well.
This allows us to declare sdhci_ops structs as const in drivers using

for CONFIG_MMC_ATMELMCI_DMA but kept the Kconfig-entry as well as the
compile guards around dma_release_channel() in remove(). Consequently,
DMA is always enabled (if supported), but the DMA-channel is not
released on module unload unless the DMA-config option is selected.
Remove the no longer used CONFIG_MMC_ATMELMCI_DMA option completely.

Commit f9c2a0dc42
"mmc: dw_mmc: Fix PIO mode with support of highmem" introduced
a regression since v3.2 making the mmc_test hang on test #13
with a "Data starvation by host timeout" interrupt.
This is because, sg_mapping_iter is used to iterate through the
data which spans on multiple pages. The problem is detected on
unaligned data submission where the code previously checked for
!(sg_next(host->sg)) which is true because we only have a single
scatter/gather list which then expands to multiple pages.
Therefore, the driver incorrectly assumed that this was the last
list item and submitted unaligned data to the mmc device. This
overflowed the FIFO on the device before all the data were written
to it. The code was fixed to only submit unaligned data when we are
handling the last sg_miter item by checking whether we reached
the desired data length or not.
The patch was tested against mmc_test and all the tests passed.

Call the setpower platform callback in response to set_ios with
ios->power_mode == MMC_POWER_UP or MMC_POWER_OFF, instead of from the
card detect work function.
This appears to fix a problem I have where a card stuck in a funny state
doesn't get properly cleared by the power being turned off, presumably
due to lack of power sequencing. This resulted in the following log

Function _mmc_detect_card_removed will be called to know whether
the card is still present when host->bus_ops->detect is called.
In current code, the return value of this function generally only
depend on the result of sending cmd13 to card, which may not safe
for card with detection support like slot gpio detection.
Because the communication status between host and card may out of
sync with the detect status if remove the card slowly or hands shake
during the process. The direct reason is the async between card
detect switch and card/slot pad contaction in hardware, which is
defined by spec.
The spec define card insert/remove sequence as below (both standard size
SD card and MicroSD card have the same sequence):
"Part 1 Standard Size SD Card Mechanical Addendum Ver4.00 Final,
Appendix C: Card Detection Switch" (Take normally open type as example)
a)SD card insertion sequence:
The card detection switch should be turned on after all SD card
contact pads are connected to the host connector contact pads.
b)SD removal sequence:
The card detection switch should be turned off when the SD card
is just going to be removed and before any SD card contact pad is
disconnected from the host connector contact pad.
Below is the sequence when this issue occur (Take slot gpio detection
as example and remove the card slowly during the process):
1. gpio level changed and card detect interrupt triggered.
2. mmc_rescan was launched.
3. the card pads were still contacted with the slot pads because of slow
removal. So _mmc_detect_card_removed and mmc_rescan think card was
still present (cmd13 succeed).
4. card pads were discontacted from the card slot pads.
So the card was actually removed finally but the card removal event
has been missed by system.
The interval length between step 1 and step 4 depends on the
card removal speed. If it's longer than the detect work schedule
delay which is 200ms, this issue will likely happen.
This patch add the card detect status check in function
_mmc_detect_card_removed if cmd13 check succeed and host->ops->get_cd
provided. If get_cd detect no card present then schedule another detect
work 200ms later.

next cycle ;-/
This pile contains 9p cleanups and fixes (races in v9fs_fid_add()
etc), fixup for nommu breakage in shmem.c, several cleanups and a bit
more file_inode() work"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
constify path_get/path_put and fs_struct.c stuff
fix nommu breakage in shmem.c
cache the value of file_inode() in struct file
9p: if v9fs_fid_lookup() gets to asking server, it'd better have hashed dentry
9p: make sure ->lookup() adds fid to the right dentry
9p: untangle ->lookup() a bit
9p: double iput() in ->lookup() if d_materialise_unique() fails
9p: v9fs_fid_add() can't fail now
v9fs: get rid of v9fs_dentry
9p: turn fid->dlist into hlist
9p: don't bother with private lock in ->d_fsdata; dentry->d_lock will do just fine
more file_inode() open-coded instances
selinux: opened file can't have NULL or negative ->f_path.dentry
(In the meantime, the hlist traversal macros have changed, so this
required a semantic conflict fixup for the newly hlistified fid->dlist)
Pull btrfs fixup from Chris Mason:
"Geert and James both sent this one in, sorry guys"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
btrfs/raid56: Add missing #include <linux/vmalloc.h>
Pull second set of s390 patches from Martin Schwidefsky:
"The main part of this merge are Heikos uaccess patches. Together with
commit 0988496433 ("mm: do not grow the stack vma just because of an
overrun on preceding vma") the user string access is hopefully fixed
for good.
In addition some bug fixes and two cleanup patches."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/module: fix compile warning
qdio: remove unused parameters
s390/uaccess: fix kernel ds access for page table walk
s390/uaccess: fix strncpy_from_user string length check
input: disable i8042 PC Keyboard controller for s390
s390/dis: Fix invalid array size
s390/uaccess: remove pointless access_ok() checks
s390/uaccess: fix strncpy_from_user/strnlen_user zero maxlen case
s390/uaccess: shorten strncpy_from_user/strnlen_user
s390/dasd: fix unresponsive device after all channel paths were lost
s390/mm: ignore change bit for vmemmap
s390/page table dumper: add support for change-recording override bit
Pull second round of PARISC updates from Helge Deller:
"The most important fix in this branch is the switch of io_setup,
io_getevents and io_submit syscalls to use the available compat
syscalls when running 32bit userspace on 64bit kernel. Other than
that it's mostly removal of compile warnings."
* 'fixes-for-3.9-latest' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: fix redefinition of SET_PERSONALITY
parisc: do not install modules when installing kernel
parisc: fix compile warnings triggered by atomic_sub(sizeof(),v)
parisc: check return value of down_interruptible() in hp_sdc_rtc.c
parisc: avoid unitialized variable warning in pa_memcpy()
parisc: remove unused variable 'compat_val'
parisc: switch to compat_functions of io_setup, io_getevents and io_submit
parisc: select ARCH_WANT_FRAME_POINTERS
This adds core architecture support for Imagination's Meta processor
cores, followed by some later miscellaneous arch/metag cleanups and
fixes which I kept separate to ease review:
- Support for basic Meta 1 (ATP) and Meta 2 (HTP) core architecture
- A few fixes all over, particularly for symbol prefixes
- A few privilege protection fixes
- Several cleanups (setup.c includes, split out a lot of metag_ksyms.c)
- Fix some missing exports
- Convert hugetlb to use vm_unmapped_area()
- Copy device tree to non-init memory
- Provide dma_get_sgtable()

Pull late ARM updates from Russell King:
"Here is the late set of ARM updates for this merge window; in here is:
- The ARM parts of the broadcast timer support, core parts merged
through tglx's tree. This was left over from the previous merge to
allow the dependency on tglx's tree to be resolved.
- A fix to the VFP code which shows up on Raspberry Pi's, as well as
fixing the fallout from a previous commit in this area.
- A number of smaller fixes scattered throughout the ARM tree"
