GenWQE: Fix multithreading problems

2014-04-16T19:12:39+00:00

When being used in a multithreaded application there were problems with memory pages/cachelines accessed by multiple threads/cpus at the same time, while doing DMA transfers to/from those. To avoid such situations this fix is creating a copy of the first and the last page if it is not fully used. The data is copied from user-space into those pages and results are copied back when the DDCB-request is successfully finished. Signed-off-by: Frank Haverkamp Signed-off-by: Greg Kroah-Hartman

GenWQE: Ensure rc is not returning an uninitialized value

2014-04-16T19:12:39+00:00

rc is not initialized, so genwqe_finish_queue() either returns -EIO or garbage. Fortunately the return is not being checked by any callers, so this has not yet caused any problems. Even so, it makes sense to fix this small bug in case is is checked in future. Signed-off-by: Colin Ian King Signed-off-by: Frank Haverkamp Signed-off-by: Greg Kroah-Hartman

GenWQE: Add wmb before DDCB is started

2014-04-16T19:12:38+00:00

Needed to add wmb() before we send the DDCB for execution. Without the syncronizing it failed on System p. Signed-off-by: Frank Haverkamp Signed-off-by: Greg Kroah-Hartman

GenWQE: Enable access to VPD flash area

2014-04-16T19:12:38+00:00

In addition to the two flash partitions we used so far, there is a 3rd one which is enabled for usage by this fix. Signed-off-by: Frank Haverkamp Signed-off-by: Greg Kroah-Hartman

Merge 3.14-rc3 into char-misc-next

2014-02-18T16:09:40+00:00

We need the fixes here for future mei and other patches. Signed-off-by: Greg Kroah-Hartman

misc: genwqe: Fix potential memory leak when pinning memory

2014-02-07T23:24:31+00:00

Fix a memory leak in the genwqe_pin_mem() error path as called by ioctl GENWQE_PIN_MEM. In case there is an error encountered when mapping memory, the already allocated dma_mapping struct needs to be freed correctly. Detected by Coverity: CID 1162606.

drivers/misc: delete non-required instances of include

2014-02-07T23:10:19+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

misc: genwqe: fix return value check in genwqe_device_create()

2014-01-08T23:22:49+00:00

In case of error, the function device_create_with_groups() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun Acked-by: Frank Haverkamp Signed-off-by: Greg Kroah-Hartman

GenWQE: Fix warnings for sparc

2014-01-08T23:22:15+00:00

dma_addr_t was not used, where it should have been used. Some format strings were not optimal. Reported-by: kbuild test robot Signed-off-by: Frank Haverkamp Signed-off-by: Greg Kroah-Hartman
