2012-05-22sh: intc: Kill off special reservation interface.Paul Mundt3-12/+0
At present reserving the IRLs in the IRQ bitmap in addition to the dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being allocated for the x3proto board. The only reason to permit reservations was to lock down possible hardware vectors prior to dynamic IRQ scanning, but this doesn't matter much given that the hardware controller configuration is sorted before we get around to doing any dynamic IRQ allocation anyways. Beyond that, all of the tables are __init annotated, so quite a bit more work would need to be done to support reconfiguring things like IRL controllers on the fly, much more than would ever make it worth the hassle.

2012-05-21sh: Enable PIO API for hp6xx and se770x.Paul Mundt1-1/+2
Both of these boards are still using the PIO API sans PCI, and will need to be carefully converted. As conversion is out of scope for this merge window, simply make sure NO_IOPORT doesn't get accidentally set for these, joining a long list of other crap platforms. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-21sh: Kill off machvec IRQ hinting.Paul Mundt22-40/+12
Everything is using sparseirq these days, so we have no need to arbitrarily size nr_irqs ahead of time. 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.

2012-05-19sh: dma: More legacy cpu dma chainsawing.Paul Mundt3-208/+177
Attempt to "tidy" up some of the multi IRQ handling and base + IRQ management. This should keep it limping along without too much hassle, and no new parts should ever be enabling or using this API anyways. It doesn't get any closer to lipstick on a pig as this. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-19sh: Kill off MAX_DMA_ADDRESS leftovers.Paul Mundt5-36/+9
We don't support the ISA DMA API, so this is only ever misused. The dma-sh case inadvertently broke the dreamcast case by testing the wrong variable for the total number of channels, so this fixes that up too. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-19sh: Tidy up some of the cpu legacy dma header mess.Paul Mundt7-52/+0
This has turned in to quite a mess, and with CPUs that care using dmaengine now it's about time to start cleaning up after the legacy DMA code. For starters, kill off the stubs for the CPUs that don't do anything, as well as all of the unused definitions. This leaves us with a set of IRQs and base addresses we can deal with later. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-19sh: Move sh4a dma header from cpu-sh4 to cpu-sh4a.Paul Mundt2-10/+1
cpu-sh4a headers take priority over cpu-sh4 ones by virtue of the build system, there's no need to try and mingle sh4a stuff in cpu-sh4. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-18sh64: Fix up vmalloc fault range check.Paul Mundt1-1/+7
With the previous attempt reverted this switches to conditionalizing the end address. Nominally VMALLOC_END, but extended for P3_ADDR_MAX in the store queue case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-18Revert "sh: Ensure fixmap and store queue space can co-exist."Paul Mundt2-3/+3
This reverts commit 20e7c297efeca0861adcca073a0d283da659834b. With store queues enabled the area above P4SEG has special properties from the MMU's point of view, which was causing fixmap failure. We'll have to do something else to satisfy the vmalloc range check. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2012-05-18serial: sh-sci: Fix for port types without BRI interrupts.Paul Mundt1-1/+18
In doing the evt2irq() + muxed vector conversion for various port types it became apparent that some of the legacy port types will presently error out due to the irq requesting logic attempting to acquire the non-existent BRI IRQ. This adds some sanity checks to the request/free path to ensure that non-existence of a source in itself is not an error. This should restore functionality for legacy PORT_SCI ports.

Pull two networking fixes from David S. Miller: 1) Thanks to Willy Tarreau and Eric Dumazet, we've unlocked a bug that's been present in do_tcp_sendpages() since that function was written in 2002. When we block to wait for memory we have to unconditionally try and push out pending TCP data, otherwise we can block for an unreasonably long amount of time. 2) Fix deadlock in e1000, fixes kernel bugzilla 43132 From Tushar Dave. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: e1000: Prevent reset task killing itself. tcp: do_tcp_sendpages() must try to push data out on oom conditions
