| |
I've tested the following patch on a i386 box with my usual .config and everything seems fine. I also tested allmodconfig and some randconfig builds and I've not seen any evident error.
I'll repeat the tests tonight on a x86_64. Other architectures should be tested as well...
Patch is against 2.6.25-rc5-mm3.
-Andrea --- On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example:
u64 val = PAGE_ALIGN(size);
always returns a value < 4GB even if size is greater than 4GB.
The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example):
#define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK)
The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask.
Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.
