Add clockevent drivers for i386: lapic (local) and PIT/HPET (global).  Update
the timer IRQ to call into the PIT/HPET driver's event handler and the
lapic-timer IRQ to call into the lapic clockevent driver.  The assignement of
timer functionality is delegated to the core framework code and replaces the
compile and runtime evalution in do_timer_interrupt_hook()

Use the clockevents broadcast support and implement the lapic_broadcast
function for ACPI.

No changes to existing functionality.

This patch updates the sata_promise driver to use new-style
libata error handling for 20619 (TX4000) chips. sata_promise
already uses new EH for the other chips it supports, so the
patch is quite simple:

* remove ->phy_reset and ->eng_timeout ops from pdc_pata_ops,
  and instead bind ->freeze, ->thaw, ->error_handler, and
  ->post_internal_cmd to existing new EH functions
* drop ATA_FLAG_SRST from board_20619's flags
* remove now unused pdc_pata_phy_reset() and pdc_eng_timeout()

Tested on a TX4000 with both modern working disks and old/quirky
disks. Also used a CD-RW drive to test reading and writing CDs.

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

There is no need for open files in /proc/sys/XXX to hold a reference count on
the module that provides the file to prevent module unload races.  While there
is code active in the module p->used in the sysctl_table_header is
incremented, preventing the sysctl from being unregisted.  Once the sysctl is
unregistered it cannot be found.  Open files are also not a problem as they
revalidate the sysctl information and bump p->used before accessing module
code.

So setting de->owner is unnecessary, makes for a bad example and gets in my
way of removing ctl_table->de.
