Subject[PATCHv4 00/10] CONFIG_DEBUG_VIRTUAL for arm64
Date

Hi,

This is v4 of the series to add CONFIG_DEBUG_VIRTUAL for arm64. This mostly
expanded on __pa_symbol conversion with a few new sites found. There's also
some reworking done to avoid calling __va too early. __va relies on having
memstart_addr set so very early code in early_fixmap_init and early KASAN
initialization can't just call __va(__Ipa_symbol(...)) to get the linear map
alias. I found this while testing with DEBUG_VM.

All of this could use probably use more testing under more configurations.
KVM, Xen, kexec, hibernate should all be tested.

Thanks,
Laura
