Current GPIO chip implementation in octeon-irq is still broken, even after upstream
commit 87161ccdc61862c8b49e75c21209d7f79dc758e9 (MIPS: Octeon: Fix broken interrupt
controller code). It works for GPIO IRQs that have reset-default configuration, but
not for edge-triggered ones.
The problem is in octeon_irq_gpio_map_common(), which passes modified "hw" variable
(which has range of possible values 16..31) as "gpio_line" parameter to
octeon_irq_set_ciu_mapping(), which saves it in private data of the IRQ chip. Later,
neither octeon_irq_gpio_setup() is able to re-configure GPIOs (cvmx_write_csr() is
writing to non-existent CVMX_GPIO_BIT_CFGX), nor octeon_irq_ciu_gpio_ack() is able
to acknowledge such IRQ, because "mask" is incorrect.
Fix is trivial and has been tested on Cavium Octeon II -based board, including
both level-triggered and edge-triggered GPIO IRQs.

The operations on the bitmap pointers are protected by "memory"
clobbering raw_local_irq_{save,restore}(), so there is no need for
volatile here. By removing the volatile we get better code generation

Currently, init_new_context() only for each online CPU, this may cause
memory corruption when CPU hotplug and fork() happens at the same time.
To avoid this, we make init_new_context() cover each possible CPU.
Scenario:
1, CPU#1 is being offline;
2, On CPU#0, do_fork() call dup_mm() and copy a mm_struct to the child;
3, On CPU#0, dup_mm() call init_new_context(), since CPU#1 is offline
and init_new_context() only covers the online CPUs, child has the
same asid as its parent on CPU#1 (however, child's asid should be 0);
4, CPU#1 is being online;
5, Now, if both parent and child run on CPU#1, memory corruption (e.g.
segfault, bus error, etc.) will occur.

This and the next patch resolve memory corruption problems while CPU
hotplug. Without these patches, memory corruption can triggered easily
as below:
On a quad-core MIPS platform, use "spawn" of UnixBench-5.1.3 (http://
code.google.com/p/byte-unixbench/) and a CPU hotplug script like this
(hotplug.sh):
while true; do
echo 0 >/sys/devices/system/cpu/cpu1/online
echo 0 >/sys/devices/system/cpu/cpu2/online
echo 0 >/sys/devices/system/cpu/cpu3/online
sleep 1
echo 1 >/sys/devices/system/cpu/cpu1/online
echo 1 >/sys/devices/system/cpu/cpu2/online
echo 1 >/sys/devices/system/cpu/cpu3/online
sleep 1
done
Run "hotplug.sh" and then run "spawn 10000", spawn will get segfault
after a few minutes.
This patch:
Currently, clear_page()/copy_page() are generated by Micro-assembler
dynamically. But they are unavailable until uasm_resolve_relocs() has
finished because jump labels are illegal before that. Since these
functions are shared by every CPU, we only call build_clear_page()/
build_copy_page() only once at boot time. Without this patch, programs
will get random memory corruption (segmentation fault, bus error, etc.)
while CPU Hotplug (e.g. one CPU is using clear_page() while another is
generating it in cpu_cache_init()).
For similar reasons we modify build_tlb_refill_handler()'s invocation.
V2:
1, Rework the code to make CPU#0 can be online/offline.
2, Introduce cpu_has_local_ebase feature since some types of MIPS CPU
need a per-CPU tlb_refill_handler().

The support for PB1100, PB1500, and PB1550 got merged into the code for
DB1000 and DB1550 code in v3.7. When that was done the three related
Kconfig symbols were dropped. But not all related Kconfig macros were
removed. Do so now.
Note that the PB1100 code in the Au1100 LCD driver is removed entirely
and not converted to use its current Kconfig macro. That is done because
the macros it uses (PB1100_G_CONTROL, PB1100_G_CONTROL_BL, and
PB1100_G_CONTROL_VDD) are never defined. Actually only one of these was
ever defined (PB1100_G_CONTROL) but that define was removed in v2.6.34.
So, as far as I can tell, this code could have never compiled.

This enables us to have a default device tree per SoC family to be built
into the kernel. The default device tree for XLP3xx has been added as part
of this change. Later this can be used to provide support default boards
for XLP2xx and XLP9xx SoCs.
Kconfig options are provided for each default device tree so that just the
needed ones can be selected to be built into the kernel.

Remove the irq save/restore from write_c0_eimr(), as it is always called
with interrupts off.
This allows us to remove workaround in write_c0_eimr() to fix up the
flags used by local_irq_save. This fixup worked on XLR, but will break
when 32-bit support is added to r2 cpus like XLP.

All the header file does is provide the internal structure of clk,
which shouldn't be used by anyone except clk.c itself anyway.

Instead of trying to use a correlation of cpu prid and chip id and
hoping they will always be unique, use the cpu prid to determine the
chip id register location and just read out the chip id.

BCM6338 and BCM6348, and BCM6358 and everything after that share the
same register layout. To not have to redefine them for each new chip
and keep the code size small, only use the definitions for the first
chip with the certain layout.

We were doing:
SRL $r,$?,16
ANDI $r,$r,0xffff
The logical right shift by 16 leaves the upper 16 bits clear, so the
subsequent masking out of those bits is redundant, and can safely be
removed.

7837314d141c661c70bc13c5050694413ecfe14a [MIPS: Get rid of branches to
.subsections] removed most uses of .subsection] removed most uses of
.subsection in inline assembler code.
It left the instances in spinlock.h alone because we knew their use was
in fairly small files where .subsection use was fine but of course this
was a fragile assumption. LTO breaks this assumption resulting in build
errors due to exceeded branch range, so remove further instances of
.subsection.
The two functions that still use .macro don't currently cause issues
however this use is still fragile.

set_except_vector() in the probe for the DADDI overflow bug resulting in a
kernel crash like this:

There are other similar places in the kernel so we've just been lucky
that GCC's been tolerant.

tlbmiss_handler_setup_pgd is run-time generated code and it was convenient
to pretend the symbol was an array in the generator but a function for
the users. LTO gcc won't tolerate this kind of lie anymore so solve the
problem through a cast and function pointer instead.

The code was written as it is because it's more expressive, a bit easier.
But it's always been dirty, if not a bug. But we can't cheat with LTO
compilers, so this results in:
