Allow the active timer (providing udelay() and currticks()) to be
selected at runtime based on probing during the INIT_EARLY stage of
initialisation.
TICKS_PER_SEC is now a fixed compile-time constant for all builds, and
is independent of the underlying clock tick rate. We choose the value
1024 to allow multiplications and divisions on seconds to be converted
to bit shifts.
TICKS_PER_MS is defined as 1, allowing multiplications and divisions
on milliseconds to be omitted entirely. The 2% inaccuracy in this
definition is negligible when using the standard BIOS timer (running
at around 18.2Hz).
TIMER_RDTSC now checks for a constant TSC before claiming to be a
usable timer. (This timer can be tested in KVM via the command-line
option "-cpu host,+invtsc".)

Apart from format specifier fixes there are two changes in proper code:
- Change type of regs in skge_hw to unsigned long
- Cast result of sizeof in myri10ge to uint32_t
Both don't change anything for i386 and should be fine on x86_64.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.

[ath5k] Save proper cacheline size when fixing PCI configuration
Some BIOSes set the PCI cacheline size to zero for the card; the ath5k
driver fixes it to a reasonable in PCI config space, but failed to
correct the internal value it had already read. This resulted in
divide-by-zero errors when cacheline-aligning various data structures.
Fix by setting the internal cachelsz to a sane value at the same time
as we write that value to PCI config space.

This adds basic rfkill support for enabling the wireless card on certain
laptops, and changes miscellaneous other details that may help in obscure
cases.
Also change the error handling to not report CRC errors, which due to the
basic facts of wireless may happen even more frequently than valid packets.
