vgsp: m100 - scan every const-bank page for data VAs; data PTEs kind 0 by default
The +0x880 trap instruction disassembles (nvdisasm on the m98b prologue
bytes) to LDG.E.U8.CONSTANT.SYS R5, [R2.64+UR4] with UR4 = c[0x4][0x0] -
the first global load's base comes from const bank 4, not the c[0x0] param
page the m99 scan covered. svc_gr_data_fill now scans every bank page the
launch carries (QMD words 32..47, even LO words: banks 0..7), deduping up
to 16 windows. Data PTEs use the gr_pte_kind param (default 0 = the kind
proven SM-visible via the const reads) instead of a hardcoded 6.
