Now that the ASIX code is supporting more than just the AX88172 devices,
make the utility function names more generic: ax8817x_func -> asix_func.
Functions that are chip specific now indicate as such: ax88772_func.

Additionally, pull some common routines used in initialization and such
into simple functions to reduce the verbosity of certain functions such
as
the bind() routines and to make the error handling consistent across the
board.

Previously, scatterlist tests didn't write patterned data.  Given how many
corner cases are addresed by them, this was a significant gap in Linux-USB
test coverage.  Moreover, when peripherals checked for correct data patterns,
false error reports would drown out the true ones.

This adds the pattern on the way OUT from the host, so scatterlist tests can
now be used to uncover bugs like host TX or peripheral RX paths failing for
back-to-back short packets.  It's easy enough to get an error there with at
least one of the {DMA,PIO}{RX,TX} code paths, or run into hardware races
that need to be defended against.

Note this patch doesn't add checking for correct data patterns on the way
IN from peripherals, just a FIXME for later.

This is two distinct changes.
 - Not changing our real parents.
 - Not changing our ptrace parents.

Not changing our real parents is trivially correct because both tasks
have the same real parents as they are part of a thread group.  Now that
we demote the leader to a thread there is no longer any reason to change
it's parentage.

Not changing our ptrace parents is a user visible change if someone
looks hard enough.  I don't think user space applications will care or
even notice.

In the practical and I think common case a debugger will have attached
to all of the threads using the same ptrace flags.  From my quick skim
of strace and gdb that appears to be the case.  Which if true means
debuggers will not notice a change.

Before this point we have already generated a ptrace event in do_exit
that reports the leaders pid has died so de_thread is visible to a
debugger.  Which means attempting to hide this case by copying flags
around appears excessive.

By not doing anything it avoids all of the weird locking issues between
de_thread and ptrace attach, and removes one case from consideration for
fixing the ptrace locking.

This only addresses Oleg's first concern with ptrace_attach, that of the
problems caused by reparenting.  Oleg's second concern is essentially a
race between ptrace_attach and release_task that causes an oops when we
get to force_sig_specific.  There is nothing special about de_thread
with respect to that race.

  [IA64] Make show_mem() skip holes in a pgdat
  [IA64] ia64_wait_for_slaves() incorrectly reports MCA

This patch modifies ia64's show_mem() to walk the vmem_map page tables and
rapidly skip forward across regions where the page tables are missing.
This prevents the pfn_valid() check from causing numerous unnecessary
page faults.

Without this patch on a 512 node 512 cpu system where every node has four
memory holes, the show_mem() call takes 1 hour 18 minutes.  With this

By calling send_sig do_SAK is recursively taking the

In addition I just audited the kernel and this was the only

it increases our options on how to fix the ptrace_attach races.
