Hi,

This is v2 of exposing shadow page tables in debugfs, there are a few
small improvements, please see below.

Changes in v2:
 - move debugfs_nv_dentry also behind CONFIG_PTDUMP_STAGE2_DEBUGFS
 - use a macro to define the file names of shadow ptdumps, also
   explicitly spell out the string to get its maximum size
 - add Reviewed-by tag from Sebastian (thanks!)
 - Link to v1: https://lore.kernel.org/kvmarm/20260308231829.864983-1-weilin.chang@arm.com/
