PKEY_ALLOW_ALL is meant to represent the pkey register value that allows all accesses (enables all pkeys). However its current naming suggests that the value applies to *one* key only (like PKEY_DISABLE_ACCESS for instance).
Rename PKEY_ALLOW_ALL to PKEY_REG_ALLOW_ALL to avoid such misunderstanding. This is consistent with the PKEY_REG_ALLOW_NONE macro introduced by commit 6e182dc9f268 ("selftests/mm: Use generic pkey register manipulation").
