2007-10-12[MIPS] Sibyte: Replace SB1 cachecode with standard R4000 class cache code.Ralf Baechle7-555/+35
It may not be perfect yet but the SB1 code is badly borken and has horrible performance issues. Downside: This seriously breaks support for pass 1 parts of the BCM1250 where indexed cacheops don't work quite reliable but I seem to be the last one on the planet with a pass 1 part anyway.

2007-10-12[MIPS] Rename CONFIG_BUILD_ELF64 into KBUILD_64BIT_SYM32Franck Bui-Huu1-7/+5
This patch renames it for 3 reasons: - "CONFIG" pattern is used by Kconfig. Now this macro is no more defined by Kconfig but by Kbuild itself make this clear by translating "CONFIG" into "KBUILD". - "ELF32" word is improper because it is irrelevant to ELF format and it makes confusion with CONFIG_BOOT_ELF32. So translate it with SYM32. - Add "64BIT" part to make clear that this macro implies a 64 bits kernel.

2007-10-12[MIPS] Remove '-mno-explicit-relocs' option when CONFIG_BUILD_ELF64Franck Bui-Huu1-3/+1
This patch removes '-mno-explicit-relocs' usage when CONFIG_BUILD_ELF64 is set since this option was only required with the old hack to truncate addresses at the assembly level where "-mabi=64 -Wa,-mabi=32" was used. This should yield a small code size improvement for inline assembly, where the R constraint is used. The idea is coming from Maciej <macro@linux-mips.org>.

2007-10-09[MIPS] Alchemy: Fix USB initialization.Florian Fainelli4-10/+10
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. [Ralf: Paolo's original patch didn't fix the module case, Florian's patch only fixed MTX1 etc. so this is a combined patch plus some cleanups.] Cc: Giuseppe Patanè <giuseppe.patane@tvblob.com> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John Crispin <blogic@openwrt.org> Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-10-08Longhaul: add auto enabled "revid_errata" optionRafal Bilski1-3/+57
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. Voltage scaling disabled longhaul: Failed to set requested frequency! longhaul: Enabling "Ignore Revision ID" option. longhaul: Failed to set requested frequency! longhaul: Disabling ACPI C3 support. longhaul: Disabling "Ignore Revision ID" option. longhaul: Failed to set requested frequency! longhaul: Enabling "Ignore Revision ID" option.

2007-10-04[SPARC64]: Temporary workaround for PCI-E slot on T1000.David S. Miller1-2/+2
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. Miller3-166/+221
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>

2007-10-02x86_64: increase VDSO_TEXT_OFFSET for ancient binutilsAndi Kleen1-1/+1
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."
