Line 827:

Maps the backing memory for a JIT memory object into the current process.

~~If operation is JitMapOperation_MapOwner~~, permission must be RW-.

For [[#MapJitOperation|MapJitOperation_MapOwner]], memory permission must be RW-.

~~If operation is JitMapOperation_MapSlave~~, permission must be R-- or R-X.

For [[#MapJitOperation|MapJitOperation_MapSlave]], memory permission must be R-- or R-X.

Operations [[#MapJitOperation|MapJitOperation_UnmapOwner/MapJitOperation_UnmapSlave]] unmap memory that was previously mapped this way.

This allows one "secure JIT" process to map the memory as RW-, and the other "slave" process to map it R-X.
