1c771f9222 After the PHYS_TO_VM_PAGE() function was de-inlined, the main reason 
to pull vm_param.h was removed.  Other big dependency of vm_page.h on
vm_param.h are PA_LOCK* definitions, which are only needed for
in-kernel code, because modules use KBI-safe functions to lock the
pages.

Stop including vm_param.h into vm_page.h. Include vm_param.h
explicitely for the kernel code which needs it.

c75943da26 Correctly return EFAULT in copyin & copyout on a fault. This fixes NFS 
when running FreeBSD on QEMU emulating a Gumstix board.

While here remove the use of a magic number in the not-XScale version.

bfba812656 Ensure we align the stack to 8 bytes in system calls. 
This is not strictly required with the current ABI but will be when we
switch to the ARM EABI. The aapcs requires the stack to be 4 byte aligned
at all times and 8 byte aligned when calling a public subroutine where the
current ABI only requires sp to be a multiple of 4.

0ff8c4269b Document the dataflash/mmc-sd issue. Add umass driver and usb. Boot 
off da0s1a instead of ate0.  Note that MMC/SD is slot B.  Until I
switch over to NAND boot, dataflash booting will preclude having SD
cards inserted at boot, so this last bit is untested.

86bce74937 Move unmask IRQ function call up to nexus device level. 
FDT-enabled targets were broken after r238043 that relies
on device up the hierarchy to properly setup interrupt.
nexus device for ARM platforms did job only partially:
setting handler but not unmasking interrupt. Unmasking
was performed by platform code.

a68d1f48b9 Complete the transition away from newbus to populate the children to 
the linker set of CPU modules.  The newbus method, although clever,
had many flaws: it didn't really support multiple SoC, many of the
comments about order were just wrong, and it did a few things far too
late to be useful.  delay and cpu_reset now work much earlier in the
boot process.
