sparc64: Fix get_user_pages_fast() wrt. THP.
[ Upstream commit 89a77915e0f56dc7b9f9082ba787895b6a83f809 ]
Mostly mirrors the s390 logic, as unlike x86 we don't need the
SetPageReferenced() bits.
On sparc64 we also lack a user/privileged bit in the huge PMDs.
In order to make this work for THP and non-THP builds, some header
file adjustments were necessary. Namely, provide the PMD_HUGE_* bit
defines and the pmd_large() inline unconditionally rather than
protected by TRANSPARENT_HUGEPAGE.
