The auth_reply handler will (re)send any pending requests. For the
initial mon authenticate phase, that's correct, but when a auth ticket
renewal races with an in-flight request, we may resend a request message
that is already in flight. Avoid this by revoking the message before
sending it.
We should also avoid resending requests at all during ticket renewal; that
will come soon.

I made a V2 of this patch on top of my patches for VFS switches.
All the changes were due to change in some offsets.
rename - change name of file or directory
size[4] Trename tag[2] fid[4] newdirfid[4] name[s]
size[4] Rrename tag[2]
The rename message is used to change the name of a file, possibly moving it
to a new directory. The 9P wstat message can only rename a file within the
same directory.

I made a V2 of this patch on top of my patches for VFS switches. The
change was adding v9fs_statfs pointer to v9fs_super_ops_dotl
instead of v9fs_super_ops.
statfs - get file system statistics
size[4] Tstatfs tag[2] fid[4]
size[4] Rstatfs tag[2] type[4] bsize[4] blocks[8] bfree[8] bavail[8]
files[8] ffree[8] fsid[8] namelen[4]
The statfs message is used to request file system information returned
by the statfs(2) system call, which is used by df(1) to report file
system and disk space usage.

Removed check to prevent hotplug of display devices within pciehp.
Originally this was thought to have been required within the PCI
Hotplug specification for some legacy devices. However there is
no such requirement in the most recent revision. The check prevents
hotplug of not only display devices but also computational GPUs
which require serviceability.

Read the memory ranges behind the Broadcom CNB20LE host bridge out of the
hardware. This allows PCI hotplugging to work, since we know which memory
range to allocate PCI BAR's from.
The x86 PCI code automatically prefers the ACPI _CRS information when it is
available. In that case, this information is not used.

At the moment only PCI-E briges can be flagged as hotplug, thus
allowing manual resource preallocation via pci=hpmemsize=nnM and
pci=hpiosize=nnM kernel parameters. Some PCI hotplug bridges, e.g.
PLX 6254 can also benefit from this functionalily, as kernel fails
to properly allocate their resources when hotplug device is added
and PCI bus is rescanned.
This patch adds header quirk for PLX 6254 that marks this bridge
as hotplug. Other PCI bridges with similar problems can use it
as well.

GCC's __builtin_prefetch() was introduced a long time ago, all
supported GCC versions have it. Lets do what the big boys up in
linux/prefetch.h do, except we use '1' as the third parameter to
provoke 'PREF 0,...' and 'PREF 1,...' instead of other prefetch
hints.
This allows for better code generation. In theory the existing
embedded asm could be optimized, but the compiler has these builtins,
so there is really no point.

ar7_regiser_devices needs ar7_clocks_init to have been called first,
however clock.o is currently linked later due to its order in the Makefile,
therefore ar7_clocks_init always gets called later than ar7_register_devices
because both have the same initcall level. Fix this by moving
ar7_register_devices to the right initcall level.

As a follow-up to the thread about RTC support for some Loongson 2E/2F
boards, this patch tries to address the "REVISIT"/"FIXME" comments about
rtc binary mode handling and allow rtc to work with rtc in binary mode.
I've also raised the message about 24-h mode not supported to warning
otherwise, one may end up with no rtc without any message in the kernel

The "nofpu" and "nodsp" kernel command line options currently do not
affect CPUs that are brought online later in the boot process or
hotplugged at runtime. It is desirable to apply the nofpu/nodsp options
to all CPUs in the system, so that surprising results are not seen when
a process migrates from one CPU to another.
[Ralf: Moved definitions of mips_fpu_disabled, fpu_disable,
mips_dsp_disabled and dsp_disable from setup.c to cpu-probe.c to allow
making mips_fpu_disabled and mips_dsp_disabled static.]
