Subject: [PATCH] xtensa: Increase size of gcc stack frame check
Date: Sat, 11 Sep 2021 19:52:35 -0700	[thread overview]
Message-ID: <20210912025235.3514761-1-linux@roeck-us.net> (raw)

xtensa frame size is larger than the frame size for almost all other
architectures. This results in more than 50 "the frame size of <n> is
larger than 1024 bytes" errors when trying to build xtensa:allmodconfig.

Increase frame size for xtensa to 1536 bytes to avoid compile errors
due to frame size limits.
