This fixes a problems with the set up of Linux memory:
- When reserving memory at boot time, the code previously reserved
the bottom page of memory, and then from one page up to the end of
the bootmap. This had the desired effect, but was strictly speaking
wrong, as the one page was actually whatever CONFIG_ZERO_PAGE_OFFSET
had been set to.

This fixes a problem in the code which copies the vmalloc portion of the
kernel's page table into the current user space page table. The addition
of the four level page table code breaks on folded page tables, because
the pud level is always present (although folded). This updates the code
to use the same style of updates for the pud as is used for the pgd
level.

Alexey Dobriyan points out:
1. simple_strtoul() silently accepts all characters for given base even
if result won't fit into unsigned long. This is amazing stupidity in
itself, but
2. nf_conntrack_irc helper use simple_strtoul() for DCC request parsing.
Data first copied into 64KB buffer, so theoretically nothing prevents
reading past the end of it, since data comes from network given 1).
This is not actually a problem currently since we're guaranteed to have
a 0 byte in skb_shared_info or in the buffer the data is copied to, but
to make this more robust, make sure the string is actually terminated.

We currently have a race when scheduling a context to a SPE -
after we have found a runnable context in spusched_tick, the same
context may have been scheduled by spu_activate().
This may result in a panic if we try to unschedule a context that has
been freed in the meantime.
This change exits spu_schedule() if the context has already been
scheduled, so we don't end up scheduling it twice.

the slack estimator used unsigned math; however for very short delay it's
possible that by the time you calculate the timeout, it's already passed and
you get a negative time/slack... in an unsigned variable... which then gets
turned into a 100 msec delay rather than zero.
