OMAP4: DSS2: HDMI: Function pointer approach to call
HDMI IP fundamentally has replaceable core PHY and PLL blocks.
These blocks might vary across OMAP's but the end functionality such as to
enable or disable PLL, PHY, function to read EDID would remain the same.
Thus to make the current hdmi DSS driver compatible with different OMAP's having
different IP blocks( A combination of different core, PHY, PLL blocks), function
pointer approach is introduced.
With function pointer, relevant IP dependent functions are mapped to the generic
functions used by DSS during the initialization based on the OMAP compiled.
Thus making hdmi DSS driver IP agnostic.

OMAP: DSS2: DISPC: Prepare dispc_dump_regs() for shortening
Prepare dispc_dump_regs() to iterate over manager and overlay id's. Doing this
requires modifications of the macro "DUMPREG" which currently needs us to specify
the manager/overlay name to get the correct result. For example, in order to
print the register DISPC_TIMING_H(OMAP_DSS_CHANNEL_LCD), we can't iterate over
a varaible i and get the desired result through DUMPREG(DISPC_TIMING_H(i)).
Split the registers into 3 sections, the first with no arguments(common
registers), the second with one argument(manager/overlay id), and the third with
two arguments(overlay id and coefficient index), redefine DUMPREG macros for
each of these.

Add missing DMA ops
For the initial architecture submission, not all of the DMA ops were
implemented. This patch adds the *map_page and *map_sg variants of the
DMA mapping ops.
This patch is currently of interest mainly to some drivers that haven't
been submitted upstream yet.

scsi: qla4xxx driver depends on NET
When CONFIG_NET is disabled, SCSI_QLA_ISCSI selects SCSI_ISCSI_ATTRS,
which uses network interfaces, so the build fails with multiple errors:
warning: (ISCSI_TCP && SCSI_CXGB3_ISCSI && SCSI_CXGB4_ISCSI && SCSI_QLA_ISCSI && INFINIBAND_ISER) selects SCSI_ISCSI_ATTRS which has unmet direct dependencies (SCSI && NET)

be020f8618ca, "ARM: entry: abort-macro: specify registers to be

names, mismatched the name used for r1. For me, this resulted in user

-mthumb broken on my OMAP1510 based Amstrad Delta (old ABI and no thumb

Fix this by using correct parameter name fsr instead of mismatched psr,

md: Fix handling for devices from 2TB to 4TB in 0.90 metadata.
0.90 metadata uses an unsigned 32bit number to count the number of
kilobytes used from each device.
This should allow up to 4TB per device.
However we multiply this by 2 (to get sectors) before casting to a
larger type, so sizes above 2TB get truncated.
Also we allow rdev->sectors to be larger than 4TB, so it is possible
for the array to be resized larger than the metadata can handle.
So make sure rdev->sectors never exceeds 4TB when 0.90 metadata is in
used.
Also the sanity check at the end of super_90_load should include level
1 as it used ->size too. (RAID0 and Linear don't use ->size at all).

md/raid1,10: Remove use-after-free bug in make_request.
A single request to RAID1 or RAID10 might result in multiple
requests if there are known bad blocks that need to be avoided.
To detect if we need to submit another write request we test:
if (sectors_handled < (bio->bi_size >> 9)) {
However this is after we call **_write_done() so the 'bio' no longer
belongs to us - the writes could have completed and the bio freed.
So move the **_write_done call until after the test against
bio->bi_size.

md/raid10: unify handling of write completion.
A write can complete at two different places:
1/ when the last member-device write completes, through
raid10_end_write_request
2/ in make_request() when we remove the initial bias from ->remaining.
These two should do exactly the same thing and the comment says they
do, but they don't.
So factor the correct code out into a function and call it in both
places. This makes the code much more similar to RAID1.
The difference is only significant if there is an error, and they
usually take a while, so it is unlikely that there will be an error
already when make_request is completing, so this is unlikely to cause
real problems.

Avoid dereferencing a 'request_queue' after last close.
On the last close of an 'md' device which as been stopped, the device
is destroyed and in particular the request_queue is freed. The free
is done in a separate thread so it might happen a short time later.
__blkdev_put calls bdev_inode_switch_bdi *after* ->release has been
called.
Since commit
f758eeabeb96f878c860e8f110f94ec8820822a9
bdev_inode_switch_bdi will dereference the 'old' bdi, which lives
inside a request_queue, to get a spin lock. This causes the last
close on an md device to sometime take a spin_lock which lives in
freed memory - which results in an oops.
So move the called to bdev_inode_switch_bdi before the call to
->release.

b03e7495a862 ("PCI: Set PCI-E Max Payload Size on fabric")
introduced a potential NULL pointer dereference in calls to

variables when the self pointer is NULL.
To correct this, verify that the self pointer in pci_bus is non-NULL
