2010-04-12MIPS: Fix SSB PCIcore IO resource managementAndreas Ferber
The SSB PCIcore code reused the IO resource fixup code from the original 2.4.x Broadcom patch for BCM47xx based devices, which was a quick hack for doing PCI IO resource configuration back then (the boot loader doesn't configure PCI devices on this platform). However, this code is no longer necessary since the kernel now can do PCI resource management fine all by itself, so remove the old code. When removing the code, it becomes obvious that the mem_offset setting in the PCIcore driver was wrong, however this was masked by the fixup code before, except in a few cases involving yenta_socket. For BCM47xx, the correct offset is 0, and since this is the only device using PCIcore in host mode, the offset can simply be removed unconditionally.

This reverts commit ba168fc37dea145deeb8fa9e7e71c748d2e00d74. It changes user-visible sysfs interfaces, and breaks some existing user space applications which apparently rely on the fact that the output does not contain the "0x" prefix.

2010-04-09drm/nv40: rework lvds table parsingBen Skeggs
All indications seem to be that the version 0x30 table should be handled the same way as 0x40 (as used on G80), at least for the parts that we currently try use. This commit cleans up the parsing to make it clearer about what we're actually trying to achieve, and unifies the 0x30/0x40 parsing. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-04-09drm/nouveau: detect vram amount once, and save the valueBen Skeggs

2010-04-08hvc_console: Fix race between hvc_close and hvc_removeAnton Blanchard
I don't claim to understand the tty layer, but it seems like hvc_open and hvc_close should be balanced in their kref reference counting. Right now we get a kref every call to hvc_open: if (hp->count++ > 0) { tty_kref_get(tty); <----- here spin_unlock_irqrestore(&hp->lock, flags); hvc_kick(); return 0; } /* else count == 0 */ tty->driver_data = hp; hp->tty = tty_kref_get(tty); <------ or here if hp->count was 0 But hvc_close has: tty_kref_get(tty); if (--hp->count == 0) { ... /* Put the ref obtained in hvc_open() */ tty_kref_put(tty); ... } tty_kref_put(tty); Since the outside kref get/put balance we only do a single kref_put when count reaches 0. The patch below changes things to call tty_kref_put once for every hvc_close call, and with that my machine boots fine.
