2024-07-04Documentation: arm64: Update memory.rst for TBIKevin Brodsky1-22/+20
Most of memory.rst was written very early, at a time where TBI (Top Byte Ignore) was not enabled. Nowadays TBI0 is always enabled, and TBI1 may be enabled, depending on the kernel configuration. This means that VA bits 63:56 cannot generally be assumed to have any particular value. Regardless of TBI, TTBRx selection is done based on bit 55; update memory.rst accordingly.

2023-06-21docs: arm64: Move arm64 documentation under Documentation/arch/Jonathan Corbet1-0/+167
Architecture-specific documentation is being moved into Documentation/arch/ as a way of cleaning up the top-level documentation directory and making the docs hierarchy more closely match the source hierarchy. Move Documentation/arm64 into arch/ (along with the Chinese equvalent translations) and fix up documentation references.
