Subject: [PATCH] riscv: fix RVG_SYSTEM_CSR_MASK width mask
Date: Fri, 11 Sep 2026 21:42:33 +0200 [thread overview]
Message-ID: <20260911194233.3379532-1-aurelien@aurel32.net> (raw)
RVG_SYSTEM_CSR_MASK should be 12 bits [31:20], shifted down by 20 bits.
Replace GENMASK(12, 0) by GENMASK(11, 0).
Fixes: cd054837243b ("riscv: Allocate user's vector context in the first-use trap")
