cris: autoconvert trivial BKL users to private mutex

All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.

None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.

Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.

CRIS: GENERIC_TIME fixes

GENERIC_TIME was not functional for CRIS, giving random backward
time jumps.

For CRISv32 implement a new clocksource using the free running counter
and ditch the arch_gettimeoffset.

The random time jumps still existed, but turned out to be the write_seqlock
which was missing around our do_timer() call.

So switch over to GENERIC_TIME using the clocksource for CRISv32.

CRISv10 doesn't have the free running counter needed for the
clocksource trick, but we can still use GENERIC_TIME with
arch_gettimeoffset.

Unfortunately, there were problems in using the prescaler register
to timer0 for the gettimeoffset calculation, so it is now ignored,
making our resolution worse by the tune of 40usec (0.4%) worst case.

At the same time, clean up some formatting and use NSEC_PER_SEC
instead of 1000000000.

sysfs: Don't allow the creation of symlinks we can't remove

that a few rare drivers are running into such that we don't always put
network devices in a class subdirectory named net/.

Since we are not creating the class directory the network devices wind
up in a non-tagged directory, but the symlinks to the network devices
from /sys/class/net are in a tagged directory.  All of which works
until we go to remove or rename the symlink.  When we remove or rename
a symlink we look in the namespace of the target of the symlink.
Since the target of the symlink is in a non-tagged sysfs directory we
don't have a namespace to look in, and we fail to remove the symlink.

Detect this problem up front and simply don't create symlinks we won't
be able to remove later.  This prevents symlink leakage and fails in
a much clearer and more understandable way.

USB: xhci: Set EP0 dequeue ptr after reset of configured device.

When a configured device is reset, the control endpoint's ring is reused.
If control transfers to the device were issued before the device is reset,
the dequeue pointer will be somewhere in the middle of the ring.  If the
device is then issued an address with the set address command, the xHCI
driver must provide a valid input context for control endpoint zero.

The original code would give the hardware the original input context,
which had a dequeue pointer set to the top of the ring.  This would cause
the host to re-execute any control transfers until it reached the ring's
enqueue pointer.  When issuing a set address command for a device that has
just been configured and then reset, use the control endpoint's enqueue
pointer as the hardware's dequeue pointer.

Assumption:  All control transfers will be completed or cancelled before
the set address command is issued to the device.  If there are any
outstanding control transfers, this code will not work.

introduced a bug that is triggered when the command ring is about to wrap.
The inc_enq() function will not have moved the enqueue pointer past the
link TRB.  It is supposed to be moved past the link TRB in prepare_ring(),

queue_command() function never calls the prepare_ring() function because
prepare_ring() is only supposed to be used for endpoint rings.  That means
the enqueue pointer will not be moved past the link TRB, and will get
overwritten.

The fix is to make queue_command() call prepare_ring() with a fake

MIPS: Alchemy: Define eth platform devices in the correct order

Currently, the eth devices are probed in the inverse order, first
au1xxx_eth1_device and then au1xxx_eth0_device. On the GPR board,
this makes trouble:

  # ifconfig|grep HWaddr
  eth0      Link encap:Ethernet  HWaddr 00:50:C2:0C:30:01
  eth1      Link encap:Ethernet  HWaddr 66:22:01:80:38:10

A bogous ethernet hwaddr is assigned to the first device and
au1xxx_eth0_device is mapped to eth1, which even does not work
properly. With this patch, the problems are gone:

  # ifconfig|grep HWaddr
  eth0      Link encap:Ethernet  HWaddr 66:22:11:32:38:10
  eth1      Link encap:Ethernet  HWaddr 66:22:11:32:38:11

MIPS: N32: Define getdents64.

As a relativly new ABI N32 should only have received the getdents64(2) but
instead it only had getdents(2).  This was noticed as a performance anomaly
in glibc.

MIPS: MTX-1: Fix PCI on the MeshCube and related boards

This patch fixes a regression introduced by commit "MIPS: Alchemy: MTX-1:
Use linux gpio api." (bb706b28bbd647c2fd7f22d6bf03a18b9552be05) which broke
PCI bus operation. The problem is caused by alchemy_gpio2_enable() which
resets the GPIO2 block. Two PCI signals (PCI_SERR and PCI_RST) are connected
to GPIO2 and they obviously do not to like the reset. Since GPIO2 is
correctly initialized by the boot monitor (YAMON) it is not necessary to
call this function, so just remove it.

Also replace gpio_set_value() with alchemy_gpio_set_value() to avoid
problems in case gpiolib gets initialized after PCI. And since alchemy
gpio_set_value() calls au_sync() we don't have to au_sync() again later.
