mark pages whose refcount were >1 and drop to 1 and are read/write writable in the pagetable right away instead of waiting for a pagefault. minor optimization. some a sanity check of SLAB-allocated pointers. vm gets its own _exit and __exit like PM, so the stock (library) panic works. 2009-04-22 14:39:29 +02:00			`EXTERN int nocheck;`

- code shared with exec() letting boot-time processes have their own fully fledged virtual address space and freeing their pre-allocated heap+stack area (necessary to let memory driver map in arbitrary areas of memory for /dev/mem without sys_vm_map) - small optimization preallocating memory on exec - finished VR_DIRECT physical mapping code 2008-12-08 17:43:20 +01:00			`EXTERN phys_bytes kernel_top_bytes;`
