Bob Liu 7160fc13e3 bfin_sport: add support for ADC/DAC. 
In order to support ADC/DAC demo, add NDSO_MODE mode to bfin_sport.c.
After that userspace apps like ndso/awg can work fine.

Al Viro 6e8bb0193a VM: make unmap_vmas() return void

Al Viro 853f5e2640 VM: don't bother with feeding upper limit to tlb_finish_mmu() in exit_mmap() 
no point, really - the only instance that cares about those arguments of
tlb_finish_mmu() is itanic and there we explicitly check if that's called
from exit_mmap() (i.e. that ->fullmm is set), in which case we ignore those
arguments completely.

Matthew Garrett a051f71ce9 hfsplus: add an ioctl to bless files 
Making an hfsplus partition bootable requires the ability to "bless" a
file by putting its inode number in the volume header. Doing this from
userspace on a mounted filesystem is impractical since the kernel will
write back the original values on unmount. Add an ioctl to allow userspace
to update the volume header information based on the target file.

Matthew Garrett 0347b6e95c hfsplus: change finder_info to u32 
The finder_info block in the hfsplus volume header is currently defined as
an array of 8 bit values, but TN1150 defines it as being an array of 32 bit
values. Fix for convenience.
