The Coccinelle script used to make this change is as follows: @haskernel@ @@ #include @depends on haskernel@ expression n,d; @@ ( - (n + d - 1) / d + DIV_ROUND_UP(n,d) | - (n + (d - 1)) / d + DIV_ROUND_UP(n,d) ) Signed-off-by: Amitoj Kaur Chawla Signed-off-by: David Vrabel --- diff --git a/arch/x86/xen/enlighten.c b/arch/x86/xen/enlighten.c index 760789ae8562..ee7d71ec762f 100644 --- a/arch/x86/xen/enlighten.c +++ b/arch/x86/xen/enlighten.c @@ -590,7 +590,7 @@ static void xen_load_gdt(const struct desc_ptr *dtr) { unsigned long va = dtr->address; unsigned int size = dtr->size + 1; - unsigned pages = (size + PAGE_SIZE - 1) / PAGE_SIZE; + unsigned pages = DIV_ROUND_UP(size, PAGE_SIZE); unsigned long frames[pages]; int f; @@ -639,7 +639,7 @@ static void __init xen_load_gdt_boot(const struct desc_ptr *dtr) { unsigned long va = dtr->address; unsigned int size = dtr->size + 1; - unsigned pages = (size + PAGE_SIZE - 1) / PAGE_SIZE; + unsigned pages = DIV_ROUND_UP(size, PAGE_SIZE); unsigned long frames[pages]; int f;
