2008-07-24PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi
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.

2008-06-04MTD/JFFS2: remove CVS keywordsAdrian Bunk
Once upon a time, the MTD repository was using CVS. This patch therefore removes all usages of the no longer updated CVS keywords from the MTD code. This also includes code that printed them to the user. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

Adding the ability to get a physical address from point() in addition to virtual address. This physical address is required for XIP of userspace code from flash.

2007-05-11[MTD] [MAPS] don't force uclinux mtd map to be root devMike Frysinger
The cheesy uclinux mtd maps can be used for more than just the root device, so I think we should drop the forcing. Also, I feel like this is a policy decision that shouldnt be in the kernel in the first place. People who have been lazy and boot with uclinux mtd maps and dont put root= into their commandline can simply add the appropriate root= line either into their bootloader or into the compiled in bootargs.

2005-09-11[PATCH] uclinux: remove use of mtd_put_device() in uclinux MTD map driverGreg Ungerer

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
