[PATCH] nfit: Fix undefined mmio_flush_range on x86_32

The following compile error was observed on x86_32 since nfit.c relies on <asm/pmem.h> to include <asm/cacheflush.h>, which only works when CONFIG_ARCH_HAS_PMEM_API is set on x86_64. drivers/acpi/nfit.c:1085:5: error: implicit declaration of function 'mmio_flush_range' [-Werror=implicit-function-declaration] Change nfit.c to include <asm/cacheflush.h> directly for now.

This is a temporary fix and please feel free to replace it with a better solution. --- drivers/acpi/nfit.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/acpi/nfit.c b/drivers/acpi/nfit.c index 82d07e8..f61e69f 100644 --- a/drivers/acpi/nfit.c +++ b/drivers/acpi/nfit.c @@ -20,6 +20,7 @@ #include <linux/sort.h> #include <linux/pmem.h> #include <linux/io.h> +#include <asm/cacheflush.h> #include "nfit.h" /*
