2008-07-24PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi1-0/+1
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.

2008-04-22[MTD] [OneNAND] Allow for controller errors when readingAdrian Hunter1-0/+15
A power loss while writing can result in a page becoming unreadable. When the device is mounted again, reading that page gives controller errors. Upper level software like JFFS2 treat -EIO as fatal, refusing to mount at all. That means it is necessary to treat the error as an ECC error to allow recovery. Note that typically in this case, the eraseblock can still be erased and rewritten i.e. it has not become a bad block.
