dma-direct: make uncached_kernel_address more general

2020-03-16T09:48:09+00:00

Rename the symbol to arch_dma_set_uncached, and pass a size to it as well as allow an error return. That will allow reusing this hook for in-place pagetable remapping. As the in-place remap doesn't always require an explicit cache flush, also detangle ARCH_HAS_DMA_PREP_COHERENT from ARCH_HAS_DMA_SET_UNCACHED.

xtensa: reorganize vectors placement

2020-02-05T05:57:02+00:00

Allow vectors to be either merged into the kernel .text or put at a fixed virtual address independently of XIP option. Drop option that puts vectors at a fixed offset from the kernel text. Add choice to Kconfig. Vectors at fixed virtual address may be useful for XIP-aware MTD support and for noMMU configurations with available IRAM. Configurations without VECBASE register must put their vectors at specific locations regardless of the selected option. All other configurations should happily use merged vectors.

Use a more generic name for additional table sorting usecases, such as the upcoming ORC table sorting feature. This tool is not tied to exception table sorting anymore.
