From dd63fdcc63f0f853b116b52e56200a0e0227cf5f Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 13 Mar 2009 03:20:49 +0100 Subject: x86: unify kmap_atomic_pfn() and iomap_atomic_prot_pfn(), fix Impact: build fix Move kmap_atomic_prot_pfn() to iomap_32.c. It is used on all 32-bit kernels, while highmem_32.c is only built on highmem kernels. ( Note: the debug_kmap_atomic_prot() check is removed for now, that problem is handled via another patch. ) Reported-by: Thomas Gleixner Cc: Akinobu Mita LKML-Reference: <20090311143317.GA22244@localhost.localdomain> Signed-off-by: Ingo Molnar --- arch/x86/mm/highmem_32.c | 20 ++------------------ 1 file changed, 2 insertions(+), 18 deletions(-) (limited to 'arch/x86/mm/highmem_32.c') diff --git a/arch/x86/mm/highmem_32.c b/arch/x86/mm/highmem_32.c index f256e73542d..522db5e3d0b 100644 --- a/arch/x86/mm/highmem_32.c +++ b/arch/x86/mm/highmem_32.c @@ -121,24 +121,8 @@ void kunmap_atomic(void *kvaddr, enum km_type type) pagefault_enable(); } -void *kmap_atomic_prot_pfn(unsigned long pfn, enum km_type type, pgprot_t prot) -{ - enum fixed_addresses idx; - unsigned long vaddr; - - pagefault_disable(); - - debug_kmap_atomic_prot(type); - - idx = type + KM_TYPE_NR * smp_processor_id(); - vaddr = __fix_to_virt(FIX_KMAP_BEGIN + idx); - set_pte(kmap_pte - idx, pfn_pte(pfn, prot)); - arch_flush_lazy_mmu_mode(); - - return (void*) vaddr; -} - -/* This is the same as kmap_atomic() but can map memory that doesn't +/* + * This is the same as kmap_atomic() but can map memory that doesn't * have a struct page associated with it. */ void *kmap_atomic_pfn(unsigned long pfn, enum km_type type) -- cgit v1.2.3
