Commit b70661c7 ("net: smc91x: use run-time configuration on all ARM machines") broke some ARM platforms through several mistakes. Firstly, the access size must correspond to the following rule: (a) at least one of 16-bit or 8-bit access size must be supported (b) 32-bit accesses are optional, and may be enabled in addition to the above. Secondly, it provides no emulation of 16-bit accesses, instead blindly making 16-bit accesses even when the platform specifies that only 8-bit is supported. Reorganise smc91x.h so we can make use of the existing 16-bit access emulation already provided - if 16-bit accesses are supported, use 16-bit accesses directly, otherwise if 8-bit accesses are supported, use the provided 16-bit access emulation. If neither, BUG(). This exactly reflects the driver behaviour prior to the commit being fixed. Since the conversion incorrectly cut down the available access sizes on several platforms, we also need to go through every platform and fix up the overly-restrictive access size: Arnd assumed that if a platform can perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access size needed to be specified - not so, all available access sizes must be specified. This likely fixes some performance regressions in doing this: if a platform does not support 8-bit accesses, 8-bit accesses have been emulated by performing a 16-bit read-modify-write access. Tested on the Intel Assabet/Neponset platform, which supports only 8-bit accesses, which was broken by the original commit.

The driver RQ has two possible configurations: striding RQ and non-striding RQ. Until this patch, the driver always reported the number of hardware WQEs (ring descriptors). For non striding RQ configuration, this was OK since we have one WQE per pending packet For striding RQ, multiple packets can fit into one WQE. For better user experience we normalize the rx_pending parameter (size of wqe/mtu) as the average ring size in case of striding RQ. Fixes: 461017cb ('net/mlx5e: Support RX multi-packet WQE ...')

Instead of asking the firmware to flush the SQ (Send Queue) via asynchronous completions when moved to error, we handle SQ flush manually (mlx5e_free_tx_descs) same as we did when SQ flush got timed out or on tx_timeout.

ConnectX-4 UMR (User Memory Region) MTT translation table offset in WQE is limited to U16_MAX, before this patch we ignored that limitation and requested the maximum possible UMR translation length that the netdev might need (MAX channels * MAX pages per channel). In case of a system with #cores > 32 and when linear WQE allocation fails, falling back to using UMR WQEs will cause the RQ (Receive Queue) to get stuck. Here we limit UMR length to min(U16_MAX, max required pages) (while considering the required alignments) on driver load, by default U16_MAX is sufficient since the default RX rings value guarantees that we are in range, dynamically (on set_ringparam/set_channels) we will check if the new required UMR length (num mtts) is still in range, if not, fail the request.

Userspace can begin and suspend a transaction within the signal handler which means they might enter sys_rt_sigreturn() with the processor in suspended state. sys_rt_sigreturn() wants to restore process context (which may have been in a transaction before signal delivery). To do this it must restore TM SPRS. To achieve this, any transaction initiated within the signal frame must be discarded in order to be able to restore TM SPRs as TM SPRs can only be manipulated non-transactionally.. >From the PowerPC ISA: TM Bad Thing Exception [Category: Transactional Memory] An attempt is made to execute a mtspr targeting a TM register in other than Non-transactional state.

In a situation, where Linux kernel gets notified about duplicate error log from OPAL, it is been observed that kernel fails to remove sysfs entries (/sys/firmware/opal/elog/0xXXXXXXXX) of such error logs. This is because, we currently search the error log/dump kobject in the kset list via 'kset_find_obj()' routine. Which eventually increment the reference count by one, once it founds the kobject. So, unless we decrement the reference count by one after it found the kobject, we would not be able to release the kobject properly later. This patch adds the 'kobject_put()' which was missing earlier.

Due to assigning the 'replaced' value instead of or'ing it, if drm_atomic_crtc_set_property() gets called multiple times, the last call will define the color_mgmt_changed flag, so a non-updating call to a property can reset the flag and prevent actual hw state updates required by preceding property updates.

Pull rdma fixes from Doug Ledford: "Round one of 4.8 rc fixes. This should be the bulk of the -rc fixes for 4.8. I only have a few things that are still outstanding (two ipoib bugs for which the solution is not yet fully known, and a few queued items that came in after my last push and I didn't want to delay this pull request for late comers again).
