Indeed. Yet, seeking for the API documented there:

 $ git grep -l pkey_mprotect
Documentation/x86/protection-keys.rst
arch/alpha/kernel/syscalls/syscall.tbl
arch/arm/tools/syscall.tbl
arch/arm64/include/asm/unistd32.h
arch/ia64/kernel/syscalls/syscall.tbl
arch/m68k/kernel/syscalls/syscall.tbl
arch/microblaze/kernel/syscalls/syscall.tbl
arch/mips/kernel/syscalls/syscall_n32.tbl
arch/mips/kernel/syscalls/syscall_n64.tbl
arch/mips/kernel/syscalls/syscall_o32.tbl
arch/parisc/kernel/syscalls/syscall.tbl
arch/powerpc/kernel/syscalls/syscall.tbl
arch/s390/kernel/syscalls/syscall.tbl
arch/sh/kernel/syscalls/syscall.tbl
arch/sparc/kernel/syscalls/syscall.tbl
arch/x86/entry/syscalls/syscall_32.tbl
arch/x86/entry/syscalls/syscall_64.tbl
arch/xtensa/kernel/syscalls/syscall.tbl
include/linux/syscalls.h
include/uapi/asm-generic/unistd.h
kernel/sys_ni.c
mm/mprotect.c
tools/include/uapi/asm-generic/unistd.h
tools/perf/arch/powerpc/entry/syscalls/syscall.tbl
tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
tools/perf/builtin-trace.c
tools/testing/selftests/x86/protection_keys.c

Despite being used on several archs, the only documentation for it
is inside the x86 directory, as it seems that this is not
arch-specific.

Perhaps the file should, instead, be moved to another book.

Thanks,
Mauro
