write{b,w,l,q}_relaxed are implemented by some architectures in order to
permit memory-mapped I/O writes with weaker barrier semantics than the
non-relaxed variants.
This patch implements these write macros for Alpha, in the same vein as
the relaxed read macros, which are already implemented.

Now IOAPIC driver dynamically allocates IRQ numbers for IOAPIC pins.
We need to keep IRQ assignment for PCI devices during runtime power
management, otherwise it may cause failure of device wakeups.
Commit 3eec595235 "x86, irq, PCI: Keep IRQ assignment for PCI
devices during suspend/hibernation" has fixed the issue for suspend/
hibernation, we also need the same fix for runtime device sleep too.

If our client is requesting a clock that is above the maximum clock
then the following division will result in 0:
rs->max_freq / rs->speed
We'll then program 0 into the SPI_BAUDR register. The Rockchip TRM
says: "If the value is 0, the serial output clock (sclk_out) is
disabled."
It's much better to end up with the fastest possible clock rather than
a clock that is off, so enforce a minimum value.

When performing a same-directory rename, it's possible that adding or
setting the new directory entry will cause the directory to overflow
the inline data area, which causes the directory to be converted to an
extent-based directory. Under this circumstance it is necessary to
re-read the directory when deleting the old dirent because the "old
directory" context still points to i_block in the inode table, which
is now an extent tree root! The delete fails with an FS error, and
the subsequent fsck complains about incorrect link counts and
hardlinked directories.
Test case (originally found with flat_dir_test in the metadata_csum
test program):
# mkfs.ext4 -O inline_data /dev/sda
# mount /dev/sda /mnt
# mkdir /mnt/x
# touch /mnt/x/changelog.gz /mnt/x/copyright /mnt/x/README.Debian

It turns out that there are some serious problems with the on-disk
format of journal checksum v2. The foremost is that the function to
calculate descriptor tag size returns sizes that are too big. This
causes alignment issues on some architectures and is compounded by the
fact that some parts of jbd2 use the structure size (incorrectly) to
determine the presence of a 64bit journal instead of checking the
feature flags.
Therefore, introduce journal checksum v3, which enlarges the
descriptor block tag format to allow for full 32-bit checksums of
journal blocks, fix the journal tag function to return the correct
sizes, and fix the jbd2 recovery code to use feature flags to
determine 64bitness.
Add a few function helpers so we don't have to open-code quite so
many pieces.
Switching to a 16-byte block size was found to increase journal size
overhead by a maximum of 0.1%, to convert a 32-bit journal with no
checksumming to a 32-bit journal with checksum v3 enabled.

The DM crypt target accesses memory beyond allocated space resulting in
a crash on 32 bit x86 systems.
This bug is very old (it dates back to 2.6.25 commit 3a7f6c990a "dm
crypt: use async crypto"). However, this bug was masked by the fact
that kmalloc rounds the size up to the next power of two. This bug
wasn't exposed until 3.17-rc1 commit 298a9fa08a ("dm crypt: use per-bio
data"). By switching to using per-bio data there was no longer any
padding beyond the end of a dm-crypt allocated memory block.
To minimize allocation overhead dm-crypt puts several structures into one
block allocated with kmalloc. The block holds struct ablkcipher_request,
cipher-specific scratch pad (crypto_ablkcipher_reqsize(any_tfm(cc))),
struct dm_crypt_request and an initialization vector.
The variable dmreq_start is set to offset of struct dm_crypt_request
within this memory block. dm-crypt allocates the block with this size:
cc->dmreq_start + sizeof(struct dm_crypt_request) + cc->iv_size.
When accessing the initialization vector, dm-crypt uses the function
iv_of_dmreq, which performs this calculation: ALIGN((unsigned long)(dmreq
+ 1), crypto_ablkcipher_alignmask(any_tfm(cc)) + 1).
dm-crypt allocated "cc->iv_size" bytes beyond the end of dm_crypt_request
structure. However, when dm-crypt accesses the initialization vector, it
takes a pointer to the end of dm_crypt_request, aligns it, and then uses
it as the initialization vector. If the end of dm_crypt_request is not
aligned on a crypto_ablkcipher_alignmask(any_tfm(cc)) boundary the
alignment causes the initialization vector to point beyond the allocated
space.
Fix this bug by calculating the variable iv_size_padding and adding it
to the allocated size.
Also correct the alignment of dm_crypt_request. struct dm_crypt_request
is specific to dm-crypt (it isn't used by the crypto subsystem at all),
so it is aligned on __alignof__(struct dm_crypt_request).
Also align per_bio_data_size on ARCH_KMALLOC_MINALIGN, so that it is
aligned as if the block was allocated with kmalloc.

Commit 43fef47f94 (mfd: twl4030-power: Add a configuration to turn
off oscillator during off-idle) added support for configuring the PMIC
to cut off resources during deeper idle states to save power.
This however caused regression for n900 display power that needed the
PMIC configuration to be disabled with commit d937678ab6 (ARM: dts:
Revert enabling of twl configuration for n900).
Turns out the root cause of the problem is that we must use
TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling
regulators that may have been enabled before the init function
for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the
regulator framework control the regulators like it should. Here we
need to only configure the sys_clken and sys_off_mode triggers for
the regulators that cannot be done by the regulator framework as
it's not running at that point.
This allows us to enable the PMIC configuration for n900.

Since this is a platform driver and can be probed at any time we can't
annotate funtions in the probe path as __init, the code can't safely be
discarded at the end of kernel init.

After commit f282ac19d8 we use different transactions for
preallocation and i_disksize update which result in complain from fsck
after power-failure. spotted by generic/019. IMHO this is regression
because fs becomes inconsistent, even more 'e2fsck -p' will no longer
works (which drives admins go crazy) Same transaction requirement
applies ctime,mtime updates

If we assign a Radeon device to a virtual machine, we can no longer
assume a fixed hardware topology, like the GPU having a parent device.
This patch simply adds a few pci_is_root_bus() tests to avoid passing
a NULL pointer to PCI access functions, allowing the radeon driver to
work in a QEMU 440FX machine with an assigned HD8570 on the emulated
PCI root bus.

This is a bit bigger hammer then I would like to use for this, but for now
it will have to make do. I'm working on getting my hands on one of these so
that I can try to get streams to work (with a quirk flag if necessary) and
then we can re-enable them.
For now this at least makes uas capable disk enclosures work again by forcing
fallback to the usb-storage driver.
