[PATCH resend 3/4] virt: vbox: Use __get_free_pages instead of kmalloc for DMA32 memory

by Hans de Goede

It is not possible to get DMA32 zone memory through kmalloc, causing the vboxguest driver to malfunction due to getting memory above 4G which the PCI device cannot handle. This commit changes the kmalloc calls where the 4G limit matters to using __get_free_pages() fixing vboxguest not working on x86_64 guests with more then 4G RAM.

[PATCH resend 2/4] virt: vbox: Add vbg_req_free() helper function

by Hans de Goede

This is a preparation patch for fixing issues on x86_64 virtual-machines with more then 4G of RAM, atm we pass __GFP_DMA32 to kmalloc, but kmalloc does not honor that, so we need to switch to get_pages, which means we will not be able to use kfree to free memory allocated with vbg_alloc_req. While at it also remove a comment on a vbg_alloc_req call which talks about Windows (inherited from the vbox upstream cross-platform code).

[PATCH v2 00/10] SWIM driver fixes

by Finn Thain

This patch series has fixes for bugs in the SWIM floppy disk controller driver, including an oops and a soft lockup. One way to apply these patches to v4.14+ is by first cherry-picking these commits: b87eaec27eca3def6c8ed617e3b1bac08d7bc715 e5f0d2e2a153b18dcf31e1a633e210c37829d759 There are of course other ways to fix the patch rejects, but this way would be convenient for me because it would simplify my own backporting. Changes since v1: - Dropped the two IOP patches as they aren't simple fixes. This way, the entire series is suitable for stable trees. - Added Cc, Fixes, Acked-by and Reviewed-by tags.

[PATCH] Bluetooth: hci_qca: Avoid missing rampatch failure with userspace fw loader

by Amit Pundir

AOSP use userspace firmware loader to load firmwares, which will return -EAGAIN in case qca/rampatch_00440302.bin is not found. Since there is no rampatch for dragonboard820c QCA controller revision, just make it work as is.

[PATCH v2] module: Fix display of wrong module .text address

by Thomas Richter

Fixes: ef0010a30935 ("vsprintf: don't use 'restricted_pointer()' when not restricting") for /sys/module/*/sections/.text file. Reading file /proc/modules shows the correct address: [root@s35lp76 ~]# cat /proc/modules | egrep '^qeth_l2' qeth_l2 94208 1 - Live 0x000003ff80401000 and reading file /sys/module/qeth_l2/sections/.text [root@s35lp76 ~]# cat /sys/module/qeth_l2/sections/.text 0x0000000018ea8363 displays a random address. This breaks the perf tool which uses this address on s390 to calculate start of .text section in memory. Fix this by printing the correct (unhashed) address. Thanks to Jessica Yu for helping on this.

[PATCH for-next 00/13] IB/hfi1,core: Driver updates for 4.17

by Dennis Dalessandro

Hi Jason and Doug, Here are most of our updates for 4.17. I will follow this up with a small 16B series then I still have a few more patches that are waiting on some more thorough testing. Should be able to get them on the list tomrrow or Friday at the latest, wanted to get these out now. I don't think anything is really that scary in here. These are mostly driver fixes. Patches 4,7,8,11, and 14 are marked stable. They didn't get sent for the -rc because they fix really old issues. Patch 5 is a core fix. I should have sent it a bit sooner, sorry about that but it's pretty trivial so I decided to include it as well rather than wait for 4.18. --- Alex Estrin (2): IB/hfi1: Complete check for locally terminated smp IB/{hfi1,qib}: Add handling of kernel restart Ashutosh Dixit (1): IB/core: Fix rkey invalidation from user space into the kernel Michael J. Ruhl (5): IB/hfi1: Return actual error value from program_rcvarray() IB/hfi1: Use after free race condition in send context error path IB/hfi1 Use correct type for num_user_context IB/hfi1: Return correct value for device state IB/hfi1: Reorder incorrect send context disable Mike Marciniszyn (3): IB/hfi1: Fix handling of FECN marked multicast packet IB/hfi1: Fix fault injection init/exit issues IB/hfi1: Fix loss of BECN with AHG Sebastian Sanchez (2): IB/hfi1: Prevent LNI hang when LCB can't obtain lanes IB/{hfi1,rdmavt,qib}: Fit kernel completions into single aligned cache-line drivers/infiniband/core/uverbs_cmd.c | 4 + drivers/infiniband/hw/hfi1/chip.c | 59 ++++++++--- drivers/infiniband/hw/hfi1/chip.h | 15 ++- drivers/infiniband/hw/hfi1/chip_registers.h | 7 + drivers/infiniband/hw/hfi1/debugfs.c | 8 + drivers/infiniband/hw/hfi1/driver.c | 19 +++- drivers/infiniband/hw/hfi1/file_ops.c | 2 drivers/infiniband/hw/hfi1/hfi.h | 9 +- drivers/infiniband/hw/hfi1/init.c | 9 +- drivers/infiniband/hw/hfi1/mad.c | 36 ++++--- drivers/infiniband/hw/hfi1/pio.c | 44 ++++++-- drivers/infiniband/hw/hfi1/rc.c | 2 drivers/infiniband/hw/hfi1/ruc.c | 54 ++++++++-- drivers/infiniband/hw/hfi1/uc.c | 2 drivers/infiniband/hw/hfi1/ud.c | 10 +- drivers/infiniband/hw/hfi1/user_exp_rcv.c | 1 drivers/infiniband/hw/qib/qib.h | 1 drivers/infiniband/hw/qib/qib_init.c | 5 + drivers/infiniband/hw/qib/qib_rc.c | 2 drivers/infiniband/hw/qib/qib_ruc.c | 4 - drivers/infiniband/hw/qib/qib_uc.c | 2 drivers/infiniband/hw/qib/qib_ud.c | 4 - drivers/infiniband/sw/rdmavt/cq.c | 146 ++++++++++++++++++--------- drivers/infiniband/sw/rdmavt/qp.c | 4 - drivers/infiniband/sw/rdmavt/trace_cq.h | 6 + include/rdma/ib_verbs.h | 5 + include/rdma/rdmavt_cq.h | 35 +++++- include/rdma/rdmavt_qp.h | 2 28 files changed, 344 insertions(+), 153 deletions(-) -- -Denny
