#     Merge branch 'address-masking'
#     
#     Merge user access fast validation using address masking.
#     
#     This allows architectures to optionally use a data dependent address
#     masking model instead of a conditional branch for validating user
#     accesses.  That avoids the Spectre-v1 speculation barriers.
#     
#     Right now only x86-64 takes advantage of this, and not all architectures
#     will be able to do it.  It requires a guard region between the user and
#     kernel address spaces (so that you can't overflow from one to the
#     other), and an easy way to generate a guaranteed-to-fault address for
#     invalid user pointers.
#     
#     Also note that this currently assumes that there is no difference
#     between user read and write accesses.  If extended to architectures like
#     powerpc, we'll also need to separate out the user read-vs-write cases.
#     
#     * address-masking:
#       x86: make the masked_user_access_begin() macro use its argument only once
#       x86: do the user address masking outside the user access area
#       x86: support user address masking instead of non-speculative conditional
