Commit-ID: 49cf3f29a1ef2e59f1be823e376c1fbac586eb8d Gitweb: http://git.kernel.org/tip/49cf3f29a1ef2e59f1be823e376c1fbac586eb8d Author: Ralf Baechle <ralf@xxxxxxxxxxxxxx> AuthorDate: Wed, 1 Jun 2011 19:05:07 +0100 Committer: Thomas Gleixner <tglx@xxxxxxxxxxxxx> CommitDate: Thu, 9 Jun 2011 15:01:40 +0200 i8253: Consolidate definitions of PIT_LATCH x86 defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as ((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines CLOCK_TICK_RATE as PIT_TICK_RATE. MIPS defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as ((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines CLOCK_TICK_RATE as 1193182. ARM defines PITCH_LATCH as ((PIT_TICK_RATE + HZ / 2) / HZ) - and that's the sanest thing and equivalent to above definitions so use that as the new definition in <linux/i8253.h>.
