There are macros that are Intel specific and not x86 generic. Rename
them into INTEL_*.
This patch removes X86_PMC_IDX_GENERIC and does:
$ sed -i -e 's/X86_PMC_MAX_/INTEL_PMC_MAX_/g' \
arch/x86/include/asm/kvm_host.h \
arch/x86/include/asm/perf_event.h \
arch/x86/kernel/cpu/perf_event.c \
arch/x86/kernel/cpu/perf_event_p4.c \
arch/x86/kvm/pmu.c
$ sed -i -e 's/X86_PMC_IDX_FIXED/INTEL_PMC_IDX_FIXED/g' \
arch/x86/include/asm/perf_event.h \
arch/x86/kernel/cpu/perf_event.c \
arch/x86/kernel/cpu/perf_event_intel.c \
arch/x86/kernel/cpu/perf_event_intel_ds.c \
arch/x86/kvm/pmu.c
$ sed -i -e 's/X86_PMC_MSK_/INTEL_PMC_MSK_/g' \
arch/x86/include/asm/perf_event.h \
arch/x86/kernel/cpu/perf_event.c

Currently pmu emulation emulates fixed counter 2 as bus cycles
architectural counter, but since commit 9c1497ea591b25d perf has
pseudo encoding for it. Use it.

If eventsel has EDGE, INV or CMASK set we should create raw counter for
it, but the check is done on a wrong variable. Fix it.
