Subject: patches: Add syscall function prototype
X-Git-Tag: RELEASE-0.14.0~7
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=2e6c8110141b2f7b853a0d48caaa5e813671949c;p=unikraft%2Flibs%2Fmusl.git

patches: Add syscall function prototype

The `sys/syscall.h` header is missing a declaration for the `syscall()`
function, which may lead to `implicit declaration` warnings that could
be treated as errors (i.e. by the GO runtime)
We also include Unikraft's `syscall_nrs2.h` header which provides
definitions for the `__NR_` macros needed by some libraries.
