Merge branch 'sg_nents' into rdma.git for-next
From Maor Gottlieb ==================== Fix the use of nents and orig_nents in the sg table append helpers. The nents should be used by the DMA layer to store the number of DMA mapped sges, the orig_nents is the number of CPU sges. Since the sg append logic doesn't always create a SGL with exactly orig_nents entries store a total_nents as well to allow the table to be properly free'd and reorganize the freeing logic to share across all the use cases. ==================== Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> * 'sg_nents': RDMA: Use the sg_table directly and remove the opencoded version from umem lib/scatterlist: Fix wrong update of orig_nents lib/scatterlist: Provide a dedicated function to support table append

- * ChangeLog:
- * .... Most of the time spent on reading sources & docs.
- * v0.2.x First official release for the Linux kernel.
- * v0.3.0 Beutified and structured, some bugs fixed.
- * v0.3.x URBifying bulk requests and bugfixing. First relatively
- * stable release. Still can touch device's registers only
- * from top-halves.
- * v0.4.0 Control messages remained unurbified are now URBs.
- * Now we can touch the HW at any time.
- * v0.4.9 Control urbs again use process context to wait. Argh...
- * Some long standing bugs (enable_net_traffic) fixed.
- * Also nasty trick about resubmiting control urb from
- * interrupt context used. Please let me know how it
- * behaves. Pegasus II support added since this version.
- * TODO: suppressing HCD warnings spewage on disconnect.
- * v0.4.13 Ethernet address is now set at probe(), not at open()
- * time as this seems to break dhcpd.
- * v0.5.0 branch to 2.5.x kernels
- * v0.5.1 ethtool support added
- * v0.5.5 rx socket buffers are in a pool and the their allocation
- * is out of the interrupt routine.
- * ...
- * v0.9.3 simplified [get|set]_register(s), async update registers
- * logic revisited, receive skb_pool removed.
