The only in kernel use of ia64_set_psr() needs to follow it with a srlz.i (since it is changing state for PSR.ic). So it is pointless to issue srlz.d inside this function. Signed-off-by:

As written, this loop could be for (;;) instead of do while (md). The tests inside the loop always result in a return so the loop never terminates normally. Signed-off-by:

This patch is purely whitespace changes to make the code fit in 80 columns, plus fix some inconsistent indentation. The efi_guidcmp() tests remain wider than 80-columns since that seems to be the most clear. Signed-off-by:

Eliminate all build warnings. OK, these build warnings are from a build on x86_64. When I build on ia64, I don't see warnings. Now builds cleanly on ia64 and x86_64.

- I removed the unnecessary barrier() from __clear_bit_unlock(). ia64_st4_rel_nta() makes sure all the modifications are globally seen before the bit is seen to be off. - I made __clear_bit() modeled after __set_bit() and __change_bit(). - I corrected some comments sating that a memory barrier is provided, yet in reality, it is the acquisition side of the memory barrier only. - I corrected some comments, e.g. test_and_clear_bit() was peaking about "bit to set".

Fixes userspace build errors when linux/ipv6.h is included such as in the dhcpv6 package under fedora. Likely causes other userspace build errors as well. I found this in akpm's tree from 2.6.18 but could not find any case of anyone proposing it for the main tree. Signed-off-by:

Drivers that register a ->fault handler, but do not range-check the offset argument, must set VM_DONTEXPAND in the vm_flags in order to prevent an expanding mremap from overflowing the resource. I've audited the tree and attempted to fix these problems (usually by adding VM_DONTEXPAND where it is not obvious). Signed-off-by:
