  "message": "fw_cfg: add generic non-DMA read method\n\nIntroduce fw_cfg_data_read(), a generic read method which works\non all access widths (1 through 8 bytes, inclusive), and can be\nused during both IOPort and MMIO read accesses.\n\nTo maintain legibility, only fw_cfg_data_mem_read() (the MMIO\ndata read method) is replaced by this patch. The new method\nessentially unwinds the fw_cfg_data_mem_read() + fw_cfg_read()\ncombo, but without unnecessarily repeating all the validity\nchecks performed by the latter on each byte being read.\n\nThis patch also modifies the trace_fw_cfg_read prototype to\naccept a 64-bit value argument, allowing it to work properly\nwith the new read method, but also remain backward compatible\nwith existing call sites.\n\nCc: Laszlo Ersek \u003clersek@redhat.com\u003e\nCc: Gerd Hoffmann \u003ckraxel@redhat.com\u003e\nCc: Marc Marí \u003cmarkmb@redhat.com\u003e\nSigned-off-by: Gabriel Somlo \u003csomlo@cmu.edu\u003e\nReviewed-by: Laszlo Ersek \u003clersek@redhat.com\u003e\nMessage-id: 1446733972-1602-6-git-send-email-somlo@cmu.edu\nSigned-off-by: Gerd Hoffmann \u003ckraxel@redhat.com\u003e\n",
