From: Ingo Molnar Date: Fri, 24 Jul 2020 11:44:17 +0000 (+0200) Subject: x86/tsc: Remove unused "US_SCALE" and "NS_SCALE" leftover macros X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=161449bad5053d66f2310744ba8498158ab12c89;p=linux.git x86/tsc: Remove unused "US_SCALE" and "NS_SCALE" leftover macros Last use of them was removed 13 years ago, when the code was converted to use CYC2NS_SCALE_FACTOR: 53d517cdbaac: ("x86: scale cyc_2_nsec according to CPU frequency") The current TSC code uses the 'struct cyc2ns_data' scaling abstraction, the old fixed scaling approach is long gone. This cleanup also removes the 'arbitralrily' typo from the comment, so win-win. ;-) Signed-off-by: Ingo Molnar Link: https://lore.kernel.org/r/20200724114418.629021-3-mingo@kernel.org --- diff --git a/arch/x86/include/asm/tsc.h b/arch/x86/include/asm/tsc.h index 8a0c25c6bf099..b7b2624fba866 100644 --- a/arch/x86/include/asm/tsc.h +++ b/arch/x86/include/asm/tsc.h @@ -7,9 +7,6 @@ #include -#define NS_SCALE 10 /* 2^10, carefully chosen */ -#define US_SCALE 32 /* 2^32, arbitralrily chosen */ - /* * Standard way to access the cycle counter. */
