Subject: [PATCH] Disable register zeroing on function exit for base and BORE
 kernels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Unset CONFIG_ZERO_CALL_USED_REGS to disable the kernel hardening
feature, allowing for older NVIDIA drivers to build successfully
against the new kernel.
