This avoids out-of-range jumps that get auto-replaced by the assembler and prepares for the changes needed to implement SECCOMP_FILTER cleanly. Signed-off-by:

Use the copy_thread_tls() calling convention which passes tls through a register. This is required so we can remove the copy_thread{_tls}() split and remove the HAVE_COPY_THREAD_TLS macro.

This switches to using common code for the DMA allocations, including potential use of the CMA allocator if configured. Switching to the generic code enables DMA allocations from atomic context, which is required by the DMA API documentation, and also adds various other minor features drivers start relying upon. It also makes sure we have on tested code base for all architectures that require uncached pte bits for coherent DMA allocations. Signed-off-by:

The code handling non-coherent DMA depends on being able to remap code as non-cached. But that can't be done without an MMU, so using this option on NOMMU builds is broken. Signed-off-by:

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

This reverts commit d1f56f31 . __delay() is an internal implementation detail on several architectures. Drivers should not call __delay() directly, as it has non-standardized semantics, or may not even exist. Hence there is no need to export __delay() to modules.
