| |
Previously the code would see if, for example, tools/perf/arch/arm/include/uapi/asm/errno.h exists and if not generate a "generic" switch statement using the asm-generic/errno.h. This creates multiple identical "generic" switch statements before the default generic switch statement for an unknown architecture. By simplifying the archlist to be only for architectures that are not "generic" the amount of generated code can be reduced from 14 down to 6 functions.
Remove the special case of x86, instead reverse the architecture names so that it comes first.
