Found on 3.2-rc4, if jump label things are enabled, the kernel will
not boot on MIPS.
As noted in patch 5/5, this was caused by: commit
97ce2c88f9ad42e3c60a9beb9fca87abf3639faa (jump-label: initialize
jump-label subsystem much earlier).
The fix is to make flush_icache_range() usable earlier. I do this by
calling cpu_cache_init() from setup_arch(). For the boot CPU we can
no longer call this from per_cpu_trap_init(), so I add a flag to that
function so we can skip the call if on the boot CPU.
Some of the code in the various cpu_cache_init() functions however
could not be called this early, so I moved it into functions called by
the new board_cache_error_setup() hook.
Tested on Octeon and ip32-R5000
David Daney (5):
MIPS: Introduce board_cache_error_setup() hook.
MIPS: Make set_handler() __cpuinit.
MIPS: Octeon: Use board_cache_error_setup for cache error handler
setup.
MIPS: Use board_cache_error_setup for r4k cache error handler setup.
MIPS: Move cache setup to setup_arch().
