early_ioremap() on IA64 chooses its mapping type based on the EFI
memory map. This patch adds an alias "early_memremap()" to be used
where the targeted location is memory rather than an i/o device.

Nothing calls omap2_onenand_rephase(). And __adjust_timing() is only
called by omap2_onenand_rephase(). Remove these two unused functions.

If audit_filter_task() nacks the new thread it makes sense
to clear TIF_SYSCALL_AUDIT which can be copied from parent
by dup_task_struct().
A wrong TIF_SYSCALL_AUDIT is not really bad, but it triggers
the "slow" audit paths in entry.S.
