MIPS: Alchemy: Rewrite GPIO support.
The current in-kernel Alchemy GPIO support is far too inflexible for
all my use cases. To address this, the following changes are made:
* create generic functions which deal with manipulating the on-chip
GPIO1/2 blocks. Such functions are universally useful.
* Macros for GPIO2 shared interrupt management and block control.
* support for both built-in CONFIG_GPIOLIB and fast, inlined GPIO macros.
If CONFIG_GPIOLIB is not enabled, provide linux gpio framework
compatibility by directly inlining the GPIO1/2 functions. GPIO access
is limited to on-chip ones and they can be accessed as documented in
the datasheets (GPIO0-31 and 200-215).
If CONFIG_GPIOLIB is selected, two (2) gpio_chip-s, one for GPIO1 and
one for GPIO2, are registered. GPIOs can still be accessed by using
the numberspace established in the databooks.
However this is not yet flexible enough for my uses: My Alchemy
systems have a documented "external" gpio interface (fixed, different
numberspace) and can support a variety of baseboards, some of which
are equipped with I2C gpio expanders. I want to be able to provide
the default 16 GPIOs of the CPU board numbered as 0..15 and also
support gpio expanders, if present, starting as gpio16.
To achieve this, a new Kconfig symbol for Alchemy is introduced,
CONFIG_ALCHEMY_GPIO_INDIRECT, which boards can enable to signal
that they don't want the Alchemy numberspace exposed to the outside
world, but instead want to provide their own. Boards are now respon-
sible for providing the linux gpio interface glue code (either in a
custom gpio.h header (in board include directory) or with gpio_chips).
To make the board-specific inlined gpio functions work, the MIPS
Makefile must be changed so that the mach-au1x00/gpio.h header is
included _after_ the board headers, by moving the inclusion of
the mach-au1x00/ to the end of the header list.
See arch/mips/include/asm/mach-au1x00/gpio.h for more info.

ext4: avoid unnecessary spinlock in critical POSIX ACL path
If a filesystem supports POSIX ACL's, the VFS layer expects the filesystem
to do POSIX ACL checks on any files not owned by the caller, and it does
this for every single pathname component that it looks up.
That obviously can be pretty expensive if the filesystem isn't careful
about it, especially with locking. That's doubly sad, since the common
case tends to be that there are no ACL's associated with the files in
question.
ext4 already caches the ACL data so that it doesn't have to look it up
over and over again, but it does so by taking the inode->i_lock spinlock
on every lookup. Which is a noticeable overhead even if it's a private
lock, especially on CPU's where the serialization is expensive (eg Intel
Netburst aka 'P4').
For the special case of not actually having any ACL's, all that locking is
unnecessary. Even if somebody else were to be changing the ACL's on
another CPU, we simply don't care - if we've seen a NULL ACL, we might as
well use it.
So just load the ACL speculatively without any locking, and if it was
NULL, just use it. If it's non-NULL (either because we had a cached
entry, or because the cache hasn't been filled in at all), it means that
we'll need to get the lock and re-load it properly.

This is noticeable even on Nehalem, which does locking quite well (much
better than P4). From lmbench:

where you can see what appears to be a roughly 3% improvement in stat
and open/close latencies from just the removal of the locking overhead.
Of course, this only matters for files you don't own (the owner never
needs to do the ACL checks), but that's the common case for libraries,
header files, and executables. As well as for the base components of any
absolute pathname, even if you are the owner of the final file.
[ At some point we probably want to move this ACL caching logic entirely
into the VFS layer (and only call down to the filesystem when
uncached), but in the meantime this improves ext3 a bit.
A similar fix to btrfs makes a much bigger difference (15x improvement
in lmbench) due to broken caching. ]

all the servers unavailable to the client. Instead the error should be
returned straight to the user.

RxRPC: Don't attempt to reuse aborted connections
Connections that have seen a connection-level abort should not be reused
as the far end will just abort them again; instead a new connection
should be made.
Connection-level aborts occur due to such things as authentication
failures.

mm: Move pgtable_cache_init() earlier
Some architectures need to initialize SLAB caches to be able
to allocate page tables. They do that from pgtable_cache_init()
so the later should be called earlier now, best is before
vmalloc_init().

fbdev: *bfin*: fix __dev{init,exit} markings
The remove member of the platform_driver bfin_t350mcqb_driver should use
__devexit_p() to refer to the remove function, and that function should
get __devexit markings. Likewise, the probe function should be marked
with __devinit and not __init.
Also, module_init() functions should be marked with __init rather than
__devinit.
