Merge tag 'alpha-for-v7.4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/lindholm/alpha

Pull alpha updates from Magnus Lindholm:
 "This completes Alpha's conversion to GENERIC_ENTRY and enables a range
  of kernel features through Kconfig updates, including UBSAN, gcov,
  kmemleak, page-table checking, fast GUP and sparse IRQs.

  It includes TLB and MMU context fixes prompted by glibc test-suite
  failures, HugeTLB support for 64KB, 512KB and 4MB pages, and fixes for
  poisoned-page faults and page-table checking.

  Machine-check handling is improved on Tsunami platforms, with bounded
  EV6 logout decoding, Clipper environmental event reporting and safer
  firmware console-log scanning.

  Other changes add self-extracting compressed kernels with support for
  all kernel compression formats, Alpha-specific XZ tuning, perf
  register and user-stack sampling, and Alpha support in the seccomp
  selftests. The series also fixes user stack-pointer reporting and IRQ
  entry ordering, adds 128-bit shift helpers, cleans up linker sections,
  and updates Kconfig help"
