| |/ / | | | | | | | | | | | | | | | | | | | | | This kills off the special sh32/64 versions and adopts the generic version. It should be possible to optimize this for SH-4A unaligned loads, but this is a corner case that can be supported incrementally. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The legacy IRQ pre-allocation likewise has no meaning for us, so that's killed off too. We now depend on nr_irqs expansion by the generic hardirq layer instead. It's also worth noting that the majority of boards had completely bogus values for their nr_irqs relative to their CPU and configurations, so this ends up correcting behaviour for quite a few platforms.

These values were never part of the sigcontext ABI and are thus never passed anywhere, so we can just kill them off across the board. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
