Revert "MIPS: Allow ASID size to be determined at boot time."
This reverts commit d532f3d26716a39dfd4b88d687bd344fbe77e390.
The original commit has several problems:
1) Doesn't work with 64-bit kernels.
2) Calls TLBMISS_HANDLER_SETUP() before the code is generated.
3) Calls TLBMISS_HANDLER_SETUP() twice in per_cpu_trap_init() when
only one call is needed.
[[email protected]: Also revert the bits of the ASID patch which were
hidden in the KVM merge.]
