We noticed that recent kernels didn't boot on our 1GHz Canyonlands 460EX boards anymore. As it seems, patch 8d165db1 [powerpc: Improve decrementer accuracy] introduced this problem. The routine div_sc() overflows with shift = 32 resulting in this incorrect setup: time_init: decrementer frequency = 1000.000012 MHz time_init: processor frequency = 1000.000012 MHz clocksource: timebase mult[400000] shift[22] registered clockevent: decrementer mult[33] shift[32] cpu[0] This patch now introduces a local div_dc64() version of this function so that this overflow doesn't happen anymore.

get_viotape_info() declares a vio_waitevent on the stack, which contains a completion, but never initialises the completion.

Commit ac4c2a3b broke the build of all powerpc boot wrappers. It attempts to add an include of autoconf.h but used the wrong path for it. It also adds -D__KERNEL__ to our boot wrapper, both things that we pretty much didn't do on purpose so far. We want our boot wrapper to remain independent enough of the kernel for various reasons, one of them being that you can "wrap" an existing kernel at distro install time which allows to ship one kernel image and a set of boot wrappers for different platforms, the wrappers don't have to be built out of the same kernel build tree. It's also incorrect to do what the patch does in our boot environment since we may not have a proper alignment exception handler which means we may not be able to fixup the few cases where an unaligned access will need SW emulation (depends on the core variant, could be when crossing page or segment boundaries for example). This patch fixes it by putting the old code back in and using the new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, which happens not to be set on powerpc since we don't include autoconf.h. It also reverts the changes to our boot wrapper Makefile. This means that x86 should, afaik, keep the optimisations since its boot wrapper does include autoconf.h and define __KERNEL__ (though I doubt they make that much different outside of slow embedded processors).

JFFS2 uses lesser compression ratio and inflate always ends up in "copy direct from output" case. This patch tries to optimize the direct copy procedure. Uses get_unaligned() but only in one place. The copy loop just above this one can also use this optimization, but I havn't done so as I have not tested if it is a win there too. On my MPC8321 this is about 17% faster on my JFFS2 root FS than the original.

mkuboot.sh provides a basic wrapper for the 'mkimage' utility. Using mkuboot.sh provides clearer error reporting and allows a toolchain to use its own 'mkimage' executable specified by ${CROSS_COMPILE}mkimage.
