of_device fields into struct pdev_archdata) missed fixing up the

of/device: Replace struct of_device with struct platform_device
of_device is just an alias for platform_device, so remove it entirely. Also
replace to_of_device() with to_platform_device() and update comment blocks.
This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

docbook: use IDs as filenames to support multiple books

link together all the cfg80211 and mac80211 documentation.
However, docbook will generate "re01.html" anew for each book for the

An effective workaround is to use IDs for the filenames, which makes
them more descriptive as well, e.g. API-enum-ieee80211-band.html.

gdbstub: do not directly use dbg_reg_def[] in gdb_cmd_reg_set()
Presently the usable registers definitions on x86 are not contiguous
for kgdb. The x86 kgdb uses a case statement for the sparse register
accesses. The array which defines the registers (dbg_reg_def) should
not be used directly in order to safely work with sparse register
definitions.
Specifically there was a problem when gdb accesses ORIG_AX, which is
accessed only through the case statement.
This patch encodes register memory using the size information provided
from the debugger which avoids the need to look up the size of the
register. The dbg_set_reg() function always further validates the
inputs from the debugger.

overflow interrupts; LOONGSON_PERFCNT_IRQ is unused so remove it.

MIPS: Loongson: Oprofile: add a new do_perfcnt_IRQ()
On FuLoong-2F IP6 is shared by the performance counter overflow interrupt
and the Bonito northbridge interrupt. To reduce overhead only call
do_IRQ() when oprofile is enabled to reduce overhead.
This patch adds an inline function do_perfcnt_IRQ() to hide the #if's ,
which can be shared by the other Loongson machines, i.e. gdium.

WATCHDOG: Add watchdog driver for OCTEON SOCs
The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit.
The driver is split into two source files one for the C code and one
for assembly. Assembly is needed to handle the NMI and then print the
machine state before the reboot is triggered.
