The Linux pkey system calls are available only if the kernel was configured and built with the CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS option. EXAMPLE.

Like mprotect(), pkey_mprotect() changes the protection on the pages specified by addr and len. The pkey argument specifies the protection key (see pkeys (7)) to assign to the memory. The protection key must be allocated with pkey_alloc (2) before it is passed to pkey_mprotect ().

1. Did you read the man page mprotect() works internally by altering the flags attached to a VMA 2. The first thing it must do is look up the VMA corresponding to the address that was passed - if the passed address was within the kernel's address range, then there is no VMA, and so this search will fail. Like mprotect(), pkey_mprotect() changes the protection on the pages specified by addr and len. The pkey argument specifies the protection key (see pkeys(7)) to assign to the memory.

The pkey argument specifies the protection key (see pkeys (7)) to assign to the memory. The protection key must be allocated with pkey_alloc (2) before it is passed to pkey_mprotect (). Description. The mprotect subroutine modifies the access protection of a mapped file or shared memory region or anonymous memory region created by the mmap subroutine.
