LPAE was enabled to support native armv7l builders running in QEMU on aarch64, but this option disables support for processors which don't support LPAE, which are still relatively common. In particular, Beaglebones use the Cortex-A8, which doesn't support LPAE. Also, if you attempt to boot an LPAE kernel on a CPU that doesn't support it, it fails before even earlycon is initialized. This makes the problem difficult to debug without enabling CONFIG_DEBUG_LL or using a hardware debugger. (cherry picked from commit 988c12f)

As this fixes a bug introduced before 21.05 was forked, yes this fits the criteria for backporting. As armv7 is not a higher tier platform, it's unlikely we had users relying on LPAE since the recent change. Especially considering native armv7 builds were not working correctly for a while. |
