fix(mm): convert MMIO to high VA, remove unsafe debug markers (!11) · Merge requests · StellaOS / OSKernel2026-StellaOS · GitLab

StellaOS requested to merge fix/mmio-high-va into main May 28, 2026

MMIO/UART/PLIC/VIRTIO addresses changed from low VA (0x1xxxxxxx) to high VA (0xFFFFFFC0_1xxxxxxx), accessible in all page tables via Boot PT's 1GB leaf PTE — fixes double-fault crash when kernel writes to UART from user page table context
Remove MMIO MapType::Identical loop in new_kernel() (now redundant)
Replace write_volatile(0x10000000, ...) debug markers with println! in boot paths; remove markers from hot paths (trap/IRQ/scheduler)
Fix mod aux → auxv (Windows reserved filename)
