IP7 will be enabled automatically in mips_clockevent_init(), if available.

d9eec1a5d6 [MIPS] time: Code cleanups
* Do not include unnecessary headers.
* Do not mention time.README.
* Do not mention mips_timer_ack.
* Make clocksource_mips static.  It is now dedicated to c0_timer.
* Initialize clocksource_mips.read statically.
* Remove null_hpt_read.
* Remove an argument of plat_timer_setup.  It is just a placeholder.

428ab280a0 [MIPS] SMP: Scatter __cpuinit over the code as needed.
MIPS doesn't do CPU hotplugging yet but since many of the functions don't
even have an __init let's fix this right.

c44e8d5e47 [MIPS] prom_free_prom_memory cleanup
Current prom_free_prom_memory() implementations are almost same as
free_init_pages(), or no-op.  Make free_init_pages() extern (again)
and make prom_free_prom_memory() use it.

2925aba422 [MIPS] Cleanup memory managment initialization.
Historically plat_mem_setup did the entire platform initialization.  This
was rather impractical because it meant plat_mem_setup had to get away
without any kind of memory allocator.  To keep old code from breaking
plat_setup was just renamed to plat_setup and a second platform
initialization hook for anything else was introduced.

e4ac58afdf [MIPS] Rewrite all the assembler interrupt handlers to C.
Saves like 1,600 lines of code, is way easier to debug, compilers
frequently do a better job than the cut and paste type of handlers many
boards had.  And finally having all the stuff done in a single place
also means alot of bug potencial for the MT ASE is gone.

The only surviving handler in assembler is the DECstation one; I hope
Maciej will rewrite it.

c1449c8fa4 [MIPS] Symmetric Uniprocessor support for Qemu.
SMP bits needed to builds and run an SMP kernel.  While only a single
processor is supported ATM it's still useful for some SMP debugging using
Qemu.
