Hi,

This series adds initial support for the Spectre variant 1 workarounds
to the kernel.  This does _not_ cover the user accessors, which are
still in development.

The series adds support for the array_index_mask_nospec() macro, used
by generic kernel code to mask out of bounds pointers, and also adds
the syscall table hardening.

For the series including v2 patch of 3/3:
