This machtype kernel command line argument will be used later to share the same kernel image file between two different machines(menglong & yeeloong) made by lemote. Thanks very much to Zhang Le for cleaning up the machtype implementation.

a platform device This patch makes the board code register the ar7_wdt driver as a platform device. We move the dynamic resource calculation here since the driver should not be aware of the AR7 SoC version it is running on.

Now that PAGE_SIZE is available to assembly directly, there is no need to separately expose it as _PAGE_SIZE through asm-offsets. In addition, remove _PAGE_SHIFT from asm-offsets, since it was never needed, and is not used anywhere.

17 00:00:00 2001 From: David Daney Date: Mon, 13 Jul 2009 11:15:19 -0700 Subject: MIPS: Allow kernel use of LL/SC to be separate from the presence of LL/SC. On some CPUs, it is more efficient to disable and enable interrupts in the kernel rather than use ll/sc for atomic operations. But if we were to set cpu_has_llsc to false, we would break the userspace futex interface (in asm/futex.h). We separate the two concepts, with a new predicate kernel_uses_llsc, that lets us disable the kernel's use of ll/sc while still allowing the futex code to use it. Also there were a couple of cases in bitops.h where we were using ll/sc unconditionally even if cpu_has_llsc were false.

It also fixes the bug in vmalloc(), which happens when its return address is not covered by the first pgd.
