  tcg: move interrupt caching and single step masking closer to user (2025-08-29 12:48:14 +0200)

----------------------------------------------------------------
* hw/i386: split isapc from PCI boards
* cpu-exec, accel: remove BQL usage for interrupt_request != 0
* memory, hpet, pmtimer: introduce BQL-free PIO/MMIO

----------------------------------------------------------------
Igor Mammedov (8):
      add cpu_test_interrupt()/cpu_set_interrupt() helpers and use them tree wide
      memory: reintroduce BQL-free fine-grained PIO/MMIO
      acpi: mark PMTIMER as unlocked
      hpet: switch to fine-grained device locking
      hpet: move out main counter read into a separate block
      hpet: make main counter read lock-less
      kvm: i386: irqchip: take BQL only if there is an interrupt
      tcg: move interrupt caching and single step masking closer to user

Mark Cave-Ayland (19):

      hw/i386/pc_piix.c: remove pcmc->pci_enabled dependent initialisation from pc_init_isa()
      hw/i386/pc_piix.c: remove igvm initialisation from pc_init_isa()
      hw/i386/pc_piix.c: remove SMI and piix4_pm initialisation from pc_init_isa()

      hw/i386/pc_piix.c: remove nvdimm initialisation from pc_init_isa()
      hw/i386/pc_piix.c: simplify RAM size logic in pc_init_isa()
      hw/i386/pc_piix.c: hardcode hole64_size to 0 in pc_init_isa()
      hw/i386/pc_piix.c: remove pc_system_flash_cleanup_unused() from pc_init_isa()
      hw/i386/pc_piix.c: always initialise ISA IDE drives in pc_init_isa()
      hw/i386/pc_piix.c: assume pcmc->pci_enabled is always true in pc_init1()
      hw/i386: move isapc machine to separate isapc.c file
      hw/i386/pc_piix.c: remove unused headers after isapc machine split
      hw/i386/pc_piix.c: replace rom_memory with pci_memory
      hw/i386/isapc.c: replace rom_memory with system_memory
