This also allows us to move some code from preprocessing to compiling (gcc culls dead code) which should help with code quality (readability, catch minor bugs, etc...).

2007-10-09[MIPS] Alchemy: Fix USB initialization.Florian Fainelli
This patch fixes a wrong ifdef in the board setup code, leading to the GPIO pin not being pulled high, and thus the USB switch not being powered at all. This finishes the rename of CONFIG_USB_OHCI to CONFIG_USB_OHCI_HCD, which started in 2005 (before 2.6.12-rc2), then probably because things were working anyway for most people got forgotten.

2007-10-07Longhaul: add auto enabled "revid_errata" optionRafal Bilski
VIA C3 Ezra-T has RevisionID equal to 1, but it needs RevisionKey to be 0 or CPU will ignore new frequency and will continue to work at old frequency. New "revid_errata" option will force RevisionKey to be set to 0, whatever RevisionID is. Additionaly "Longhaul" will not silently ignore unsuccessful transition. It will try to check if "revid_errata" or "disable_acpi_c3" options need to be enabled for this processor/system. Same for Longhaul ver. 2 support. It will be disabled if none of above options will work. Best case scenario (with patch apllied and v2 enabled): longhaul: VIA C3 'Ezra' [C5C] CPU detected. Longhaul v2 supported. longhaul: Using northbridge support. longhaul: VRM 8.5 longhaul: Max VID=1.350 Min VID=1.050, 13 possible voltage scales longhaul: f: 300000 kHz, index: 0, vid: 1050 mV [...] longhaul: Voltage scaling enabled. Worst case scenario: longhaul: VIA C3 'Ezra-T' [C5M] CPU detected. Powersaver supported. longhaul: Using northbridge support. longhaul: Using ACPI support. longhaul: VRM 8.5 longhaul: Claims to support voltage scaling but min & max are both 1.250.

2007-10-03[SPARC64]: Temporary workaround for PCI-E slot on T1000.David S. Miller
The PCI-E slot on T1000 connects directly to the Fire PCI chip with no intervening bridges visible in the OBP tree. Unfortunately the bus numbering of the device in that slot is different (2) from the PCI host controller (0), and thus the pci_bus_{read,write}_config_*() calls don't work out. Complicating things further the Fire PCI controller has no config space it responds to either. For now treat this case specially so that devices in the slot work. Longer term we need to perhaps cons up a dummy bridge between the Fire and the PCI-E slot so that the bus hierarchy is complete inside of the kernel and thus the bus numbering all works out right.

2007-10-02[SPARC64]: Fix missing load-twin usage in Niagara-1 memcpy.David S. Miller
For the case where the source is not aligned modulo 8 we don't use load-twins to suck the data in and this kills performance since normal loads allocate in the L1 cache (unlike load-twin) and thus big memcpys swipe the entire L1 D-cache. We need to allocate a register window to implement this properly, but that actually simplifies a lot of things as a nice side-effect. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-10-01x86_64: increase VDSO_TEXT_OFFSET for ancient binutilsAndi Kleen
For some reason old binutils genertate larger headers so increase the text offset of the vdso to avoid linker errors. Roland McGrath explains: "There are extra symbols in the '.dynsym' section that are responsible for the size difference (They also cause corresponding inflation in '.gnu.version') Older ld's wrongly generated these unneeded symbols in .dynsym. This was fixed not all that long ago (2006); binutils-2.17.50.0.6 might be the first fixed version, but I have not verified for sure where the cutoff was. The unneeded symbols et al from old ld add almost 700 bytes excess. This limits fairly tightly the amount by which the actual text and data in the vDSO can grow in the future without pushing the whole file over 4kb. If it does grow later on, we should consider changing the layout with a config option or something to pack it better without that padding, when building the kernel with newer binutils."

2007-10-02[POWERPC] Fix xics set_affinity codeAnton Blanchard
On a POWER6 machine running 2.6.23-rc8 I sometimes see the following error: xics_set_affinity: No online cpus in the mask 00000000,00000000,00000000,00000001 for irq 20 In a desperate attempt to get a changelog entry in 2.6.23, I took a look into it. It turns out we are passing a real and not a virtual irq into get_irq_server. This works for the case where hwirq < NR_IRQS and we set virq = hwirq. In my case however hwirq = 590082 and we try and access irq_desc[590082], slightly past the end at 512 entries. Lucky we ship lots of memory with our machines.
