Due to a processor anomaly (05000263 to be exact), most Blackfin parts
cannot keep the embedded filesystem image directly after the kernel in
RAM.  Instead, the filesystem needs to be relocated to the end of memory.
As such, we need to tweak the map addr/size during boot for Blackfin
systems.  This can be done in any early arch/board init code.

<title>PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architectures</title>
<updated>2008-07-24T17:47:21+00:00</updated>
<author>
<name>Andrea Righi</name>

<link rel='alternate' type='text/html' href='https://git.toradex.cn/cgit/linux-toradex.git/commit/?id=27ac792ca0b0a1e7e65f20342260650516c95864'/>
<id>27ac792ca0b0a1e7e65f20342260650516c95864</id>
<content type='text'>
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 &lt; 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) &lt;&lt; PAGE_SHIFT)
#define PAGE_MASK       (~(PAGE_SIZE-1))
...
#define PAGE_ALIGN(addr)       (((addr)+PAGE_SIZE-1)&amp;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.

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This patch therefore removes all usages of the no longer updated CVS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.

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.
