[Qemu-devel] [PATCH v2 01/13] spice: Use cpu_register_physical_memory_log for dirty log enabling

[Jan Kiszka <jan.kiszka@siemens.com>]

Drop outdated dirty log disable/enable around PCI remapping and register
the BAR for dirty logging via cpu_register_physical_memory_log. That
allows to remove all vga_dirty_log_start/stop references from qxl.
