From: Andrew Morton John's about to nuke x86's monotonic clock without grepping for it first. The patch lamely borrows the ppc64 code for x86. hangcheck-timer shouldn't be doing it this way a) HAVE_MONOTONIC should be CONFIG_MONOTONIC_CLOCK and it should be defined in arch/xxx/Kconfig. b) That ifdef tangle shouldn't be in hangcheck-timer.c. It should be using arch-provided helper functions, which CONFIG_MONOTONIC_CLOCK-enabling architectures implement in arch/something.c Cc: john stultz Cc: Joel Becker Signed-off-by: Andrew Morton --- drivers/char/hangcheck-timer.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff -puN drivers/char/hangcheck-timer.c~hangcheck-remove-monotomic_clock-on-x86 drivers/char/hangcheck-timer.c --- devel/drivers/char/hangcheck-timer.c~hangcheck-remove-monotomic_clock-on-x86 2006-03-22 20:55:56.000000000 -0800 +++ devel-akpm/drivers/char/hangcheck-timer.c 2006-03-22 20:56:39.000000000 -0800 @@ -117,12 +117,12 @@ __setup("hcheck_reboot", hangcheck_parse __setup("hcheck_dump_tasks", hangcheck_parse_dump_tasks); #endif /* not MODULE */ -#if defined(CONFIG_X86) || defined(CONFIG_S390) +#if defined(CONFIG_X86_64) || defined(CONFIG_S390) # define HAVE_MONOTONIC # define TIMER_FREQ 1000000000ULL #elif defined(CONFIG_IA64) # define TIMER_FREQ ((unsigned long long)local_cpu_data->itc_freq) -#elif defined(CONFIG_PPC64) +#else # define TIMER_FREQ (HZ*loops_per_jiffy) #endif _
