Perfmon support (used by oprofile earlier) was removed by commit
ecf5b72d5f ("ia64: Remove perfmon") earlier, but it missed few files
to remove/update.
Clean it up.

Unlike the kernel space, exported headers are written in standard C.
- Forbid C++ style comments
- Use 'inline', 'asm' instead of 'inline', 'asm'
-std=c90 (equivalent to -ansi) catches the violation of those.
We cannot go as far as adding -Wpedantic since it emits too many warnings.
UAPI_CFLAGS := -std=c90 -Wall -Werror=implicit-function-declaration
In theory, we do not care -m32 or -m64 for header compile tests.
It is here just because CONFIG_CC_CAN_LINK is tested with -m32 or -m64.
UAPI_CFLAGS += $(filter -m32 -m64, $(KBUILD_CFLAGS))
override c_flags = $(UAPI_CFLAGS) -Wp,-MMD,$(depfile) -I$(objtree)/usr/include
The following are excluded for now because they fail to build.
Do not add a new header to the blacklist without legitimate reason.
Please consider to fix the header first.
