Subject: [XTENSA] Prevent inlining ISS platform asm constructs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c865415838146d83c92e4c1ae69aff45ef9f35f8;p=linux-beck.git

[XTENSA] Prevent inlining ISS platform asm constructs

The simcall asm macro assumes Windowed ABI parameter passing
in registers, and doesn't work if its containing function gets
inlined.  This fix prevents that from happening.
