[Qemu-devel] [PATCH, RFC] mips: fix cpu_reset memory leak

[Blue Swirl <blauwirbel@gmail.com>]

Both mmu_init() and mvp_init() allocate structures, so call cpu_mips_register
only when creating a CPU.

In addition, maybe some of the some of the field initialization stuff
in  cpu_mips_register, mmu_init, mvp_init, fpu_init etc. should be
moved to cpu_reset instead, in case the fields should be reset to
original values during CPU reset. Maximally only the env->mvp etc.
structure allocation would be left to cpu_mips_register. This is the
minimal version, but it may be incorrect. Comments?
