The PB1550 is more or less a DB1550 without the PCI IDE controller,
a more complicated (read: configurable) Flash setup and some other
minor changes. Like the DB1550 it can be automatically detected by
reading the CPLD ID register bits.
This patch adds PB1550 detection and setup to the DB1550 code.

Change the indicator from 0xffffffff in the "event_id" member to
zero in the "cntr_mask" member. This removes the need to initialize
entries that are unsupported. This also solves a problem where the
number of entries in the table was increased based on a globel enum
used for all platforms, but the new unsupported entries were not added
for mips. This was leaving new table entries of all zeros that we not
marked UNSUPPORTED.

We can save an instruction in the TLB Refill path for kernel mappings
by aligning swapper_pg_dir on a 64K boundary. The address of
swapper_pg_dir can be generated with a single LUI instead of
LUI/{D}ADDUI.
The alignment of __init_end is bumped up to 64K so there are no holes
between it and swapper_pg_dir, which is placed at the very beginning
of .bss.
The alignment of invalid_pmd_table and invalid_pte_table can be
relaxed to PAGE_SIZE. We do this by using __page_aligned_bss, which
has the added benefit of eliminating alignment holes in .bss.

I've maintained this patch, originally from Thiemo Seufer in 2004, for a
really long time, but I think it's time for it to get a look at for
possible inclusion. I have had no problems with it across various SGI
systems over the years.
To quote the post here:
http://www.linux-mips.org/archives/linux-mips/2004-12/msg00000.html
"the atomic functions use so far memory references for the inline
assembler to access the semaphore. This can lead to additional
instructions in the ll/sc loop, because newer compilers don't
expand the memory reference any more but leave it to the assembler.
The appended patch uses registers instead, and makes the ll/sc
arguments more explicit. In some cases it will lead also to better
register scheduling because the register isn't bound to an output
any more."

Pull i2c-embedded changes from Wolfram Sang:
"The changes for i2c-embedded include:
- massive rework of the omap driver
- massive rework of the at91 driver. In fact, the old driver gets
removed; I am okay with this approach since the old driver was
depending on BROKEN and its limitations made it practically
unusable, so people used bitbanging instead. But even if there are
users, there is no platform_data or module parameter which would
need to be converted. It is just another driver doing I2C
transfers, just way better. Modifications of arch/arm/at91 related
files have proper acks from the maintainer.
- new driver for R-Car I2C
- devicetree and generic_clock conversions and fixes
- usual driver fixes and changes.
The rework patches have come a long way and lots of people have been
involved in creating/testing them. Most patches have been in
linux-next at least since 3.6-rc5. A few have been added in the last
week, I have to admit.
An unexpected (but welcome :)) peak in private life is the cause for
that. The "late" patches shouldn't cause any merge conflicts and I
will have a special eye on them during the stabilization phase. This
is an exception and I want to have the patches in place properly in
time again for the next kernels."

Commit 6b8029fab6 ("rtc: kconfig: remove unnecessary dependencies")
removed various 'depends on RTC_CLASS' dependencies but also removed a
few 'default RTC_CLASS' statements, which actually changed default
behavior.
This resulted in the various RTC interfaces (sysfs, proc, dev) all being
disabled by default, even when RTC_CLASS is enabled:
# CONFIG_RTC_INTF_SYSFS is not set
# CONFIG_RTC_INTF_PROC is not set
# CONFIG_RTC_INTF_DEV is not set
which is different from previous behavior (all of these where enabled.)
To fix, add back the 'default RTC_CLASS' statments to each of the
RTC_INTF_* options.
I noticed this because some RTC tests started failing on my TI OMAP
platforms because /dev/rtc0 was not present anymore, even though the
driver was present and RTC_CLASS was enabled.

Update discovery process initialization based on Andrew Morton's comments:
https://lkml.org/lkml/2012/10/3/552.
This update processes all enumerating mports first and schedules discovery
work after that. If the initialization routine fails to allocate resources
needed to execute discovery, it abandons discovery for all ports.

The virq_disabled flag tracks the userspace view of INTx masking
across interrupt mode changes, but we're not consistently applying
this to the interrupt and masking handler notion of the device.
Currently if the user sets DisINTx while in MSI or MSIX mode, then
returns to INTx mode (ex. rebooting a qemu guest), the hardware has
DisINTx+, but the management of INTx thinks it's enabled, making it
impossible to actually clear DisINTx. Fix this by updating the
handler state when INTx is re-enabled.

We need to be ready to recieve an interrupt as soon as we call
request_irq, so our eventfd context setting needs to be moved
earlier. Without this, an interrupt from our device or one
sharing the interrupt line can pass a NULL into eventfd_signal
and oops.

Our mmap path mistakely relied on vma->vm_pgoff to get set in
remap_pfn_range. After b3b9c293, that path only applies to
copy-on-write mappings. Set it in our own code.

Features include:
- Remove CONFIG_EXPERIMENTAL dependency from NFSv4.1
Aside from the issues discussed at the LKS, distros are shipping
NFSv4.1 with all the trimmings.
- Fix fdatasync()/fsync() for the corner case of a server reboot.
- NFSv4 OPEN access fix: finally distinguish correctly between
open-for-read and open-for-execute permissions in all situations.
- Ensure that the TCP socket is closed when we're in CLOSE_WAIT
- More idmapper bugfixes
- Lots of pNFS bugfixes and cleanups to remove unnecessary state and
make the code easier to read.
- In cases where a pNFS read or write fails, allow the client to
resume trying layoutgets after two minutes of read/write-through-mds.
- More net namespace fixes to the NFSv4 callback code.
- More net namespace fixes to the NFSv3 locking code.
- More NFSv4 migration preparatory patches.
Including patches to detect network trunking in both NFSv4 and NFSv4.1
- pNFS block updates to optimise LAYOUTGET calls.
