2013-04-09USB: remove USB_EHCI_BIG_ENDIAN_{DESC,MMIO} depends on architecture symbolFlorian Fainelli
Just like the OHCI counter part we just can remove the architecture specific symbols which prevent these configuration symbols from being selected by platforms/architectures requiring it. The original implementation did not scale at all since it required each and every single architecture to be added for these configuration symbols to be selected. Now it is up to the EHCI driver and/or platform to select these configuration symbols accordingly.

In commit 887cbce0adea ("arch Kconfig: centralise ARCH_NO_VIRT_TO_BUS") I introduced the config sybmol HAVE_VIRT_TO_BUS and selected that where needed. I am not sure what I was thinking.

The MIPS implementation of transparent huge-pages (THP) is 64-bit only, and of course also requires that the CPU supports huge-pages. Currently it's entirely possible to enable THP in other configurations, which then fail to build due to pfn_pmd() not being defined.

2012-11-17irq_work: Remove CONFIG_HAVE_IRQ_WORKFrederic Weisbecker
irq work can run on any arch even without IPI support because of the hook on update_process_times(). So lets remove HAVE_IRQ_WORK because it doesn't reflect any backend requirement.

2012-11-09MIPS: Netlogic: Fix DMA zone selection for 64-bitJayachandran C
Fix Kconfig for both XLR and XLP to select ZONE_DMA32 (instead of ZONE_DMA) in case of 64-bit compilation. This can be used for devices that can only do DMA to 32-bit address. ZONE_DMA is not useful on XLR or XLP. Signed-off-by: Jayachandran C <jchandra@broadcom.com> Patchwork: http://patchwork.linux-mips.org/patch/4466 Signed-off-by: John Crispin <blogic@openwrt.org>

This allows us to use the r2 optimized code from kernel headers while compilation. Disable PGD_C0_CONTEXT option for XLP, which does not work. Signed-off-by: Jayachandran C <jchandra@broadcom.com> Patchwork: http://patchwork.linux-mips.org/patch/4456 Signed-off-by: John Crispin <blogic@openwrt.org>
