The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @haskernel@ @@ #include @depends on haskernel@ expression x,__divisor; @@ - (((x) + ((__divisor) / 2)) / (__divisor)) + DIV_ROUND_CLOSEST(x,__divisor) // Signed-off-by: Julia Lawall --- arch/mips/nxp/pnx8550/common/time.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/arch/mips/nxp/pnx8550/common/time.c b/arch/mips/nxp/pnx8550/common/time.c index 8df43e9..18b1927 100644 --- a/arch/mips/nxp/pnx8550/common/time.c +++ b/arch/mips/nxp/pnx8550/common/time.c @@ -138,7 +138,7 @@ __init void plat_time_init(void) * HZ timer interrupts per second. */ mips_hpt_frequency = 27UL * ((1000000UL * n)/(m * pow2p)); - cpj = (mips_hpt_frequency + HZ / 2) / HZ; + cpj = DIV_ROUND_CLOSEST(mips_hpt_frequency, HZ); write_c0_count(0); timer_ack();
