Subject[PATCH v12 0/4] fw_cfg: add DMA operations & etc/vmcoreinfo support
Date
Hi,

This series adds DMA operations support to the qemu fw_cfg kernel
module and populates "etc/vmcoreinfo" with vmcoreinfo location
details (entry added since qemu 2.11 with -device vmcoreinfo).

v12:
- fix virt_to_phys(NULL) panic with CONFIG_DEBUG_VIRTUAL=y
- do not use DMA read, except for kmalloc() memory we allocated
ourself (only fw_cfg_register_dir_entries() so far)

v11:
- add #include <linux/crash_core.h> in last patch,
fixing kbuild .config test

Marc-André Lureau (4):
fw_cfg: add DMA register
fw_cfg: do DMA read operation
crash: export paddr_vmcoreinfo_note()
fw_cfg: write vmcoreinfo details
