I've put up an updated patch at http://avr32linux.org/twiki/pub/Main/LinuxPatches/avr32-arch-3.patch
which fixes most of the issues people have pointed out. Thanks a lot to everyone for taking the time to look through this.
I've appended the changelog below, but first I'll mention the things I didn't fix and why:
There are three libgcc functions left, which handle the three possible variants of 64-bit shift. There's no easy way to eliminate these, but maybe our gcc maintainer can get gcc to emit the instructions inline instead. However, these functions are actually specified by the AVR32 ABI, so they should be the same no matter which compiler you use.
The clk API is still exported as non-GPL. I don't feel very strongly one way or another, but since Russell is keeping them non-GPL on ARM, it makes most sense to keep them non-GPL on AVR32 as well.
I've kept the volatiles in the arguments to the bitops functions as they are. I'm not sure if they're really needed, but as I understood from reading the recent thread about spinlocks, this doesn't fall in the category of "obviously bad" usage of volatile.
Here's the shortlog: Add MAINTAINERS entries for AVR32 and AT32AP Remove EARLY_PRINTK support Remove CONFIG_DW_DMAC symbol Remove DMA controller framework Add Kbuild file for 'make headers_install' on AVR32 Remove #ifdef __KERNEL__ from asm/atomic.h Remove #ifdef __KERNEL__ from asm/bitops.h Remove #ifdef __KERNEL__ from asm/dma-mapping.h Remove #ifdef __KERNEL__ from asm/mmu_context.h Remove #ifdef __KERNEL__ from asm/semaphore.h Remove #ifdef __KERNEL__ from asm/thread_info.h Move PAGE_SIZE and friends inside #ifdef __KERNEL__ Wrap __FD_SET and friends inside __KERNEL__ Kill _syscall[0123456]() and hand-code execve() instead Remove obsolete #include <linux/config.h> Replace MB -> MiB and KB -> KiB Wire up 39 new syscalls Use do_div() instead of open-coded div64 in time_init() Use for_each_online_cpu in show_interrupts() Add asm/futex.h Ensure kprobes compiles again Switch to genirq framework Fix cpu_idle preempt bug Process softirqs the usual way Handle preempt in the interrupt- and exception handlers
