non-multiple of 64 bytes. Thereafter, the user state save area is
misaligned, which triggers assertion in the debugging kernels, or
segmentation violation on accesses for non-debugging configs.
Force the desired alignment of the user save area as the fix
(workaround is to disable bit 9 in the hw.xsave_mask loader tunable).
This correction is required for booting on the upcoming Intel' Purley
platform.
