[PATCH 00/19] tip queue 2015-06-25 (rdtsc cleanup)

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

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@xxxxxxx

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()

  x86/asm: Save an instruction in DECLARE_ARGS users
