Hi,
This series adds DMA operations support to the qemu fw_cfg kernel module and populates "etc/vmcoreinfo" with vmcoreinfo location details.
Note: the support for this entry handling has been merged for next qemu release (2.11)
v4: - export paddr_vmcoreinfo_note() to fix fw_cfg.ko build - fix build with !CONFIG_CRASH_CORE - replace the unbounded yield() loop with a usleep_range() loop and a 200ms timeout - do not write vmcoreinfo entry when running the kdump kernel (D. Hatayama) - drop the experimental sysfs write support patch from this series
v3: (thanks kbuild) - add "fw_cfg: fix the command line module name" patch - fix build of "fw_cfg: add DMA register" with CONFIG_FW_CFG_SYSFS_CMDLINE=y - fix 'Wshift-count-overflow'
v2: - use platform device for dma mapping - add etc/vmcoreinfo patch - some code cleanups
Marc-André Lureau (5): fw_cfg: fix the command line module name fw_cfg: add DMA register fw_cfg: do DMA read operation crash: export paddr_vmcoreinfo_note() fw_cfg: write vmcoreinfo details
