Hi,
here's the RDTSC cleanup series from Andy + one from George. I've collected and tested them ontop of 407a2c720556.
Later pm+acpi pull request will introduce a stray native_read_tsc(), see https://lkml.kernel.org/r/20150624213824.GI32642@pd.tnic
Andy Lutomirski (18): x86/tsc: Inline native_read_tsc() and remove __native_read_tsc() x86/msr, kvm: Remove vget_cycles() x86/kernel/paravirt: Remove read_tsc() and read_tscp() paravirt hooks x86/tsc: Replace rdtscll() with native_read_tsc() x86/tsc: Remove the rdtscp() and rdtscpll() macros x86/tsc: Use the full 64-bit TSC in delay_tsc() x86/cpu/amd: Use the full 64-bit TSC to detect the 2.6.2 bug drivers/net/hamradio/baycom_epp: Replace rdtscl() with native_read_tsc() staging/lirc_serial: Remove TSC-based timing input/joystick/analog: Switch from rdtscl() to native_read_tsc() drivers/input/gameport: Replace rdtscl() with native_read_tsc() x86/asm: Remove rdtscl() x86: Rename native_read_tsc() to rdtsc() x86: Add rdtsc_ordered() and use it in trivial call sites x86/tsc_sync: Use rdtsc_ordered() in check_tsc_warp() and drop extra barriers x86/tsc: Use rdtsc_ordered() in read_tsc() instead of get_cycles() x86/kvm/tsc: Drop extra barrier and use rdtsc_ordered() in kvmclock x86/asm: Remove rdtsc_barrier()
