Revert "ARM: 6944/1: mm: allow ASID 0 to be allocated to tasks"
This reverts commit 45b95235b0ac86cef2ad4480b0618b8778847479. Will Deacon reports that: In 52af9c6c ("ARM: 6943/1: mm: use TTBR1 instead of reserved context ID") I updated the ASID rollover code to use only the kernel page tables whilst updating the ASID. Unfortunately, the code to restore the user page tables was part of a later patch which isn't yet in mainline, so this leaves the code quite broken. We're also in the process of eliminating __ARCH_WANT_INTERRUPTS_ON_CTXSW from ARM, so lets revert these until we can properly sort out what we're doing with the context switching.
