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