commit 2b0a2bff6091ad255a94d9905cdaccdaaddbd927
Author: Szabolcs Nagy <szabolcs.nagy@arm.com>
Date:   Fri Oct 21 12:10:11 2022 +0100

    aarch64: morello: define PROT_MAX
    
    Specifies the prot flags a mapping may gain via mprotect or MAP_FIXED.
    On CHERI targets this is used to get capability with more permissions
    than the original mmap protection would imply.
