Mouad-Scriptz-0andClaude Fable 5.1 df3d027ebe perf(libkernel): find guest allocations and direct mappings by address ...

sceKernelVirtualQuery, sceKernelMunmap, sceKernelReleaseDirectMemory and the
reservation paths walked a copy of the whole allocation registry or of every
direct mapping under one lock on each call. The registry now answers lookups
from its ordered map, applies range replacements as patches instead of
rebuilding the map, and direct mappings carry an index by physical offset so a
release finds only the mappings it covers. Minecraft (PPSA17221) holds about
7,000 direct mappings and spent its world generation in these walks.
