xtensa: add seccomp support

2020-07-28T07:57:06+00:00

Add SECCOMP to xtensa Kconfig, select HAVE_ARCH_SECCOMP_FILTER, add TIF_SECCOMP and call secure_computing from do_syscall_trace_enter. Signed-off-by: Max Filippov

xtensa: add audit support

2020-07-28T07:57:05+00:00

All bits needed for syscall audit are present on xtensa. Add audit_syscall_entry and audit_syscall_exit calls and select HAVE_ARCH_AUDITSYSCALL in Kconfig. Signed-off-by: Max Filippov

arch: remove HAVE_COPY_THREAD_TLS

2020-07-04T21:41:37+00:00

All architectures support copy_thread_tls() now, so remove the legacy copy_thread() function and the HAVE_COPY_THREAD_TLS config option. Everyone uses the same process creation calling convention based on copy_thread_tls() and struct kernel_clone_args. This will make it easier to maintain the core process creation code under kernel/, simplifies the callpaths and makes the identical for all architectures.

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.
