On an SMP system with cache aliases, the following sequence of events may happen: 1) copy_user_highpage() runs on CPU0, invoking kmap_coherent() to create a temporary mapping in the fixmap region 2) copy_page() starts on CPU0 3) CPU1 sends CPU0 an IPI asking CPU0 to run local_r4k_flush_cache_page() 4) CPU0 takes the interrupt, interrupting copy_page() 5) local_r4k_flush_cache_page() on CPU0 calls kmap_coherent() again 6) The second invocation of kmap_coherent() on CPU0 tries to use the same fixmap virtual address that was being used by copy_user_highpage() 7) CPU0 throws a machine check exception for the TLB address conflict Fixed by creating an extra set of fixmap entries for use in interrupt handlers. This prevents fixmap VA conflicts between copy_user_highpage() running in user context, and local_r4k_flush_cache_page() invoked from an SMP IPI. Signed-off-by:

This patch removes the calls to bcm63xx_uart_register in board_bcm963xx.c and make bcm63xx_uart_register an initfunc. Allows us to remove bcm63xx_dev_uart.h which was there to make checkpatch.pl happy. Signed-off-by:

This patch fixes a lockup on BCM6345 where setting the PLL soft reset bit will also lock the other blocks including UART. Instead of setting only the PLL soft reset bit in the software reset register, set this bit but do not touch the others. Signed-off-by:

We've silently been relying on the hardware chopping off excess, reserved ASID bits for no better reason that it saving an instruction. Because we already have: #define cpu_asid(cpu, mm) (cpu_context((cpu), (mm)) & ASID_MASK) in <asm/mmu_context.h>. We can use a cleanup to avoid writing non-zero bits into the reserved entryhi bits. This avoid triggering some debugging assertion in the Cavium simulator. Signed-off-by:

Don't pass NULL pointers to fput() in the error handling paths of the NOMMU do_mmap_pgoff() as it can't handle it. The following can be used as a test program: int main() { static long long a[1024 * 1024 * 20] = { 0 }; return a;} Without the patch, the code oopses in atomic_long_dec_and_test() as called by fput() after the kernel complains that it can't allocate that big a chunk of memory. With the patch, the kernel just complains about the allocation size and then the program segfaults during execve() as execve() can't complete the allocation of all the new ELF program segments.
