If an ATA drive uses legacy mode, ata driver will choose 14 and 15
as the fixed irq number. On ia64 platform, such numbers are GSI and
should be converted to irq vector.
Below patch against kernel 2.6.20 fixes it.

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.

While doing the C99 conversion I notices that the top level sh64 directory was
using the binary number for CTL_KERN. That is a no-no so I removed the
support for the sysctl binary interface only leaving sysctl /proc support.
At least the sysctl tables were placed at the end of the list so user space
did not see this mistake.

While C99 converting the ctl_table initializers I realized that the binary
sysctl numbers were in conflict with the binary values under CTL_KERN.
Including CTL_KERN KERN_VERSION as used by glibc. So I just removed the
sysctl binary interface for these values, as it was unsupportable.
Luckily these sysctl were inserted at the end of the sysctl list so this bug
was not visible to userspace.

The assignment of binary numbers for sys_sysctl use was in shambles and

This convters the sysctl ctl_tables to use C99 initializers. While I was
looking at it I discovered it was using a portion of the sysctl binary
addresses space under CTL_KERN KERN_OSTYPE which was completely inappropriate.
So I completely removed all of the sysctl binary names, to remove and avoid
the ABI conflict.

By not using the enumeration in sysctl.h (or even understanding it) the SN
platform placed their arch specific xpc directory on top of CTL_KERN and only
because they didn't have 4 entries in their xpc directory got lucky and didn't
break glibc.
This is totally irresponsible. So this patch entirely removes sys_sysctl
support from their sysctl code. Hopefully they don't have ascii name
conflicts as well.
And now that they have no ABI numbers add them to the end instead of the
sysctl list instead of the head so nothing else will be overridden.

udbg_early_init() is a function used on 64 bit systems, which
initializes whichever early udbg backend is configured. This function
is not called on 32-bit, however if btext early debug is enabled it
does have an explicit, inline, #ifdef-ed assignment performing
analagous initialization.
This patch makes things more uniform by folding the btext
initialization as an option into udbg_early_init() and calling that
from the 32-bit setup path.

This can be used for serial ports that are connected to an
OF platform bus but are not autodetected by the lecacy
serial support.
It will automatically take over devices that come from the
legacy serial detection, which usually is only one device.
In some cases, rtas may be set up to use the serial port
in the firmware, which allows easier debugging before probing
the serial ports. In this case, the "used-by-rtas" property
must be set by the firmware. This patch also adds code to the
legacy serial driver to check for this.
