2017-05-24scsi: qedi: Fix bad pte call trace when iscsiuio is stopped.Arun Easi1-12/+11
munmap done by iscsiuio during a stop of the service triggers a "bad pte" warning sometimes. munmap kernel path goes through the mmapped pages and has a validation check for mapcount (in struct page) to be zero or above. kzalloc, which we had used to allocate udev->ctrl, uses slab allocations, which re-uses mapcount (union) for other purposes that can make the mapcount look negative. Avoid all these trouble by invoking one of the __get_free_pages wrappers to be used instead of kzalloc for udev->ctrl. BUG: Bad page map in process iscsiuio pte:80000000aa624067 pmd:3e6777067 page:ffffea0002a98900 count:2 mapcount:-2143289280 mapping: (null) index:0xffff8800aa624e00 page flags: 0x10075d00000090(dirty|slab) page dumped because: bad pte addr:00007fcba70a3000 vm_flags:0c0400fb anon_vma: (null) mapping:ffff8803edf66e90 index:0 Call Trace: dump_stack+0x19/0x1b print_bad_pte+0x1af/0x250 unmap_page_range+0x7a7/0x8a0 unmap_single_vma+0x81/0xf0 unmap_vmas+0x49/0x90 unmap_region+0xbe/0x140 ? vma_rb_erase+0x121/0x220 do_munmap+0x245/0x420 vm_munmap+0x41/0x60 SyS_munmap+0x22/0x30 tracesys+0xdd/0xe2 Signed-off-by: Arun Easi <arun.easi@cavium.com> Signed-off-by: Manish Rangankar <manish.rangankar@cavium.com> Signed-off-by: Martin K.

2017-05-18qed: Utilize FW 8.20.0.0Mintz, Yuval3-13/+13
This pushes qed [and as result, all qed* drivers] into using 8.20.0.0 firmware. The changes are mostly contained in qed with minor changes to qedi due to some HSI changes. Content-wise, the firmware contains fixes to various issues exposed since the release of the previous firmware, including: - Corrects iSCSI fast retransmit when data digest is enabled. - Stop draining packets when receiving several consecutive PFCs. - Prevent possible assertion when consecutively opening/closing many connections. - Prevent possible assertion due to too long BDQ fetch time. In addition, the new firmware would allow us to later add iWARP support in qed and qedr.

2017-03-14qed*: Utilize Firmware 8.15.3.0Mintz, Yuval8-618/+1423
This patch advances the qed* drivers into using the newer firmware - This solves several firmware bugs, mostly related [but not limited to] various init/deinit issues in various offloaded protocols. It also introduces a major 4-Cached SGE change in firmware, which can be seen in the storage drivers' changes. In addition, this firmware is required for supporting the new QL41xxx series of adapters; While this patch doesn't add the actual support, the firmware contains the necessary initialization & firmware logic to operate such adapters [actual support would be added later on].
