But why doesn't the 1 << 41 version work with both 44 and 46-bit VA?

It should be:

   || `[0x0a0000000000, 0x3fffffffffff]` || HighMem    ||

   || `[0x034000000000, 0x09ffffffffff]` || HighShadow ||

   || `[0x024000000000, 0x033fffffffff]` || ShadowGap  ||

   || `[0x020000000000, 0x023fffffffff]` || LowShadow  ||

   || `[0x000000000000, 0x01ffffffffff]` || LowMem     ||

then, which IMHO should work just fine even if 0x100000000000 through

0x3fffffffffff is unavailable.
