H A D | systbl.c | 8640de0d Wed Sep 21 01:55:58 CDT 2022 Rohan McLure <rmclure@linux.ibm.com> powerpc: Use common syscall handler type
Cause syscall handlers to be typed as follows when called indirectly throughout the kernel. This is to allow for better type checking.
typedef long (*syscall_fn)(unsigned long, unsigned long, unsigned long, unsigned long, unsigned long, unsigned long);
Since both 32 and 64-bit abis allow for at least the first six machine-word length parameters to a function to be passed by registers, even handlers which admit fewer than six parameters may be viewed as having the above type.
Coercing syscalls to syscall_fn requires a cast to void* to avoid -Wcast-function-type.
Fixup comparisons in VDSO to avoid pointer-integer comparison. Introduce explicit cast on systems with SPUs.
