   4 Subject: RISC-V: Update AT_VECTOR_SIZE_ARCH for new AT_MINSIGSTKSZ
   5
   6 From: Victor Isaev <victor@torrio.net>

   8 [ Upstream commit 13dddf9319808badd2c1f5d7007b4e82838a648e ]
   9
  10 "riscv: signal: Report signal frame size to userspace via auxv" (e92f469)
  11 has added new constant AT_MINSIGSTKSZ but failed to increment the size of
  12 auxv, keeping AT_VECTOR_SIZE_ARCH at 9.
  13 This fix correctly increments AT_VECTOR_SIZE_ARCH to 10, following the
  14 approach in the commit 94b07c1 ("arm64: signal: Report signal frame size
  15 to userspace via auxv").
