    pkeys: add support of PKEY_DISABLE_READ
Thanks.  In the x86 code, the translation of PKEY_DISABLE_READ |
PKEY_DISABLE_WRITE to PKEY_DISABLE_ACCESS appears to be missing.  I
believe the existing code produces PKEY_DISABLE_WRITE, which is wrong.
ah. yes. good point.

Rest looks okay to me (again not tested).
thanks,
