Subject: MIPS: __raw_spin_lock() may spin forever on ticket wrap.

If the lock is not acquired and has to spin *and* the second attempt
to acquire the lock fails, the delay time is not masked by the ticket
range mask.  If the ticket number wraps around to zero, the result is
that the lock sampling delay is essentially infinite (due to casting
-1 to an unsigned int).

The fix: Always mask the difference between my_ticket and the current
ticket value before calculating the delay.

Subject: MIPS: Compat: Zero upper 32-bit of offset_high and offset_low.

Through sys_llseek() arguably should do exactly that it doesn't which
means llseek(2) will fail for o32 processes if offset_low has bit 31 set.

As suggested by Heiko Carstens.

Subject: MIPS: EMMA2RH: Use handle_edge_irq() handler for GPIO interrupts

EMMA's GPIO interrupts are latched by GPIO interrupt status register.
In this case, we're encouraged to use handle_edge_irq() handler.

The following changes are made along with replacing set_irq_chip() with
set_irq_chip_and_handler_name(,,handle_edge_irq,"edge"):

* Fix emma2rh_gpio_irq_ack not to disable interrupts

  With handle_edge_irq(), we're not expected to disable interrupts
  when chip->ack is served, so fix it accordingly.  We also add a new
  emma2rh_gpio_irq_mask_ack() for chip->mask_ack operation, instead.

* Remove emma2rh_gpio_irq_end(), as chip->end is no longer served.

Subject: MIPS: Malta: make a needlessly global integer variable static

The variable `mips_revision_corid' is needlessly defined global in
arch/mips/mti-malta/malta-init.c, and this patch makes it static.

Build-tested with malta_defconfig.

Subject: MIPS: Fix global namespace pollution in arch/mips/kernel/smp-up.c

The following symbols in arch/mips/kernel/smp-up.c are needlessly
defined global:

up_send_ipi_single()
up_init_secondary()
up_smp_finish()
up_cpus_done()
up_boot_secondary()
up_smp_setup()
up_prepare_cpus()

This patch makes the symbols static.

Build-tested using malta_defconfig.

Subject: MIPS: Make a needlessly global symbol static in
 arch/mips/kernel/smp.c

The variable cpu_callin_map is needlessly defined global, so let's
make it static now.

Build-tested using malta_defconfig.

Subject: MIPS: Alchemy: unify CPU model constants.

This patch removes the various CPU_AU1??? model constants in favor of
a single CPU_ALCHEMY one.

All currently existing Alchemy models are identical in terms of cpu
core and cache size/organization.  The parts of the mips kernel which
need to know the exact CPU revision extract it from the c0_prid register
already; and finally nothing else in-tree depends on those any more.

Should a new variant with slightly different "company options" and/or
"processor revision" bits in c0_prid appear, it will be supported
immediately (minus an exact model string in cpuinfo).

Subject: MIPS: Alchemy: MIPS hazard workarounds are not required.

The Alchemy manuals state:

"All pipeline hazards and dependencies are enforced by hardware interlocks
 so that any sequence of instructions is guaranteed to execute correctly.
 Therefore, it is not necessary to pad legacy MIPS hazards (such as
 load delay slots and coprocessor accesses) with NOPs."

Run-tested on Au12x0, without any ill effects.
