There have been a number of compile problems with the msp71xx configuration
ever since it was included in the linux-mips.org repository.  This patch
resolves compilation problems with attempting to reset the board using
non-existent GPIO routines.

This patch has been compile-tested against the current HEAD.

There have been a number of compile problems with the msp71xx configuration

resolves the "multiple definition of plat_timer_setup" problem, and creates
the required get_c0_compare_int function.

Addition of -fwrapv option in 2.6.29 discloses possible overflow with
signed arithmetics.  For example, result of "a * 6 / 12" (int a =
400000000) is 200000000 without -fwrapv but -157913941 with -fwrapv.

Change some variable to unsigned to avoid such overflows.

This reverts commit a425a638.

Now that the previous commit removed the "readpage" actor for hugetlb
files, read-ahead will no longer mess up the mapping, and there's no
longer any reason to treat hugetlbfs mappings specially.

The core VM assumes the page size used by the address_space in
inode->i_mapping is PAGE_SIZE but hugetlbfs breaks this assumption by
inserting pages into the page cache at offsets the core VM considers
unexpected.

This would not be a problem except that hugetlbfs also provide a
->readpage implementation.  As it exists, the core VM can assume the
base page size is being used, allocate pages on behalf of the
filesystem, insert them into the page cache and call ->readpage to
populate them.  These pages are the wrong size and at the wrong offset
for hugetlbfs causing confusion.

This patch deletes the ->readpage implementation for hugetlbfs on the
grounds the core VM should not be allocating and populating pages on
behalf of hugetlbfs.  There should be no existing users of the
->readpage implementation so it should not cause a regression.
