This patch resolves a "BUG: unable to handle kernel paging request at ..."
oops while dumping packet data. The issue occurs with IOMMU enabled due to
the address provided by phys_to_virt().
This patch makes use of skb->data on Tx and the virtual address of the pages
allocated for Rx.

This set includes a major redesign of recording the master node for
resources. The old dir hash table, which just held the master node for
each resource, has been removed. The rsb hash table has always duplicated
the master node value from the dir, and is now the single record of it.
Having two full hash tables of all resources has always been a waste,
especially since one just duplicated a single value from the other.
Local requests will now often require one instead of two lengthy hash
table searches.
The other substantial change is made possible by the dirtbl removal, and
fixes a long standing race between resource removal and lookup by
reworking how removal is done. At the same time it improves the
efficiency of removal by avoiding repeated searches through a hash bucket.
The other commits include minor fixes and changes.

pch_uart_interrupt() takes priv->port.lock which leads to two recursive
spinlock calls if low_latency==1 or CONFIG_PREEMPT_RT_FULL=y (one
otherwise):
pch_uart_interrupt
spin_lock_irqsave(priv->port.lock, flags)
case PCH_UART_IID_RDR_TO (data ready)
handle_rx_to
push_rx
tty_port_tty_get
spin_lock_irqsave(&port->lock, flags) <--- already hold this lock
...
tty_flip_buffer_push
...
flush_to_ldisc
spin_lock_irqsave(&tty->buf.lock)
spin_lock_irqsave(&tty->buf.lock)
disc->ops->receive_buf(tty, char_buf)
n_tty_receive_buf
tty->ops->flush_chars()
uart_flush_chars
uart_start
spin_lock_irqsave(&port->lock) <--- already hold this lock
Avoid this by using a dedicated lock to protect the eg20t_port structure
and IO access to its membase. This is more consistent with the 8250
driver. Ensure priv->lock is always take prior to priv->port.lock when
taken at the same time.
V2: Remove inadvertent whitespace change.
V3: Account for oops_in_progress for the private lock in
pch_console_write().
Note: Like the 8250 driver, if a printk is introduced anywhere inside
the pch_console_write() critical section, the kernel will hang
on a recursive spinlock on the private lock. The oops case is
handled by using a trylock in the oops_in_progress case.

pm_restore_console() is called from the suspend/resume path, and this
calls vt_move_to_console(), which calls vt_waitactive().
There's a race in this path which causes the process which requests the
suspend to sleep indefinitely waiting for an event which already
happened:
P1 P2
vt_move_to_console()
set_console()
schedule_console_callback()
vt_waitactive()
check n == fg_console +1
console_callback()
switch_screen()
vt_event_post() // no waiters
vt_event_wait() // forever
Fix the race by ensuring we're registered for the event before we check
if it's already completed.

Recently, glibc made a change to suppress sign-conversion warnings in
FD_SET (glibc commit ceb9e56b3d1). This uncovered an issue with the
kernel's definition of __NFDBITS if applications #include
<linux/types.h> after including <sys/select.h>. A build failure would
be seen when passing the -Werror=sign-compare and -D_FORTIFY_SOURCE=2
flags to gcc.
It was suggested that the kernel should either match the glibc
definition of __NFDBITS or remove that entirely. The current in-kernel
uses of __NFDBITS can be replaced with BITS_PER_LONG, and there are no
uses of the related __FDELT and __FDMASK defines. Given that, we'll
continue the cleanup that was started with commit 8b3d1cda4f
("posix_types: Remove fd_set macros") and drop the remaining unused
macros.
Additionally, linux/time.h has similar macros defined that expand to
nothing so we'll remove those at the same time.

Since Grant is even more specacularly busy than usual for the time being
I've been collecting SPI patches for him for this release - probably
things will revert back to Grant before the next release. There's
nothing too exciting here, mostly it's simple driver specific stuff:
- Add spi: to the modaliases of SPI devices to provide namespacing.
- A driver for AD-FMCOMMS1-EBZ.
- DT binding for Orion.
- Fixes and cleanups for i.MX, PL0022, OMAP and bitbang drivers.
There may be a few more fixes I've missed, people keep sending me new
things.

Commit b9562545ef ("bcma: complete workaround for BCMA43224 and
BCM4313") introduced the wrong masks for setting the chip control
registers - the "mask" parameter is inverse.
It should be the mask of bits *not* changed, which is admittedly a bit
non-intuitive.
The incorrect mask not only causes the driver to not work correctly on
the chips affected (eg the BCM43224 on the Macbook Air 4,2) but the
state persists over a soft reset, causing the next boot to not
necessarily see the device correctly.

The wrong interrupts where assigned to the cores in
bcma_core_mips_init(). This caused at least my serial console not to
response to any input.
This was caused by this patch which changed the order of the cores in
the list:
commit c334e25c9f
Author: Rafał Miłecki <zajec5@gmail.com>
Date: Wed Jul 11 12:37:00 2012 +0200
bcma: add new cores at the end of list
This should be fixed properly later so that the correct interrupt
numbers are assigned to the cores independently from the ordering of
the list. This patch restores the old behavior again. I will look into
the problem more deeply later.
I also changed the order of the list with the cores and their assigned
interrupt number which gets printed to the log. Now they are printed in
the same order like all the other lists of cores and like it was done
before the patch which changed the order.

Here's the big staging tree merge for the 3.6-rc1 merge window.
There are some patches in here outside of drivers/staging/, notibly the iio
code (which is still stradeling the staging / not staging boundry), the pstore
code, and the tracing code. All of these have gotten ackes from the various
subsystem maintainers to be included in this tree. The pstore and tracing
patches are related, and are coming here as they replace one of the android
staging drivers.
Otherwise, the normal staging mess. Lots of cleanups and a few new drivers
(some iio drivers, and the large csr wireless driver abomination.)
Note, you will get a merge issue with the following files:
drivers/staging/comedi/drivers/s626.h
drivers/staging/gdm72xx/netlink_k.c
both of which should be trivial for you to handle.

Daniel writes: (this pull is the one with the bad patch dropped)
First pile of fixes for 3.6 already, and I'm afraid it's a bit larger than
what I'd wish for. But I've moved all the feature-y stuff to -next, so
this really is all -fixes. Most of it is handling fallout from the hw
context stuff, discovered now that mesa git has started using them for
real. Otherwise all just small fixes:
- unbreak modeset=0 on gen6+ (regressed in next)
- const mismatch fix for ->mode_fixup
- simplify overly clever lvds modeset code (current code can totally
confuse backlights, resulting in broken panels until a full power draw
restores them).
- fix some fallout from the flushing_list disabling (regression only
introduced in -next)
- DP link train improvements (this also kills the last 3.2 dp regression
afaik)
- bugfix for the new ddc VGA detection on newer platforms
- minor backlight fixes (one of them a -next regression)
- only enable the required PM interrupts (to avoid waking up the cpu
unnecessarily)
- some really minor bits (workaround clarification, make coverty happy,
hsw init fix)
