backport of IB/isert commit to '5.10.y' stable release

by Krishnamraju Eraparaju

Hi Greg, Could you please backport the below commit to "5.10.y" stable release. Looks like this commit was already pulled to "5.10.y" stable tree weeks ago. This fix is required for Chelsio adapters. Without this fix the number of connections supported by isert(over Chelsio adapter) will be significantly less. -------------------------------------------------------- commit ID: dae7a75f1f19bffb579daf148f8d8addd2726772 IB/isert: add module param to set sg_tablesize for IO cmd Author: Max Gurtovoy <mgurtovoy(a)nvidia.com> Fixes: 317000b ("IB/isert: allocate RW ctxs according to max IO size") Thanks, Krishnamraju.

[PATCH 1/2] hugetlb: fix update_and_free_page contig page struct assumption

by Mike Kravetz

page structs are not guaranteed to be contiguous for gigantic pages. The routine update_and_free_page can encounter a gigantic page, yet it assumes page structs are contiguous when setting page flags in subpages. If update_and_free_page encounters non-contiguous page structs, we can see “BUG: Bad page state in process …” errors. Non-contiguous page structs are generally not an issue. However, they can exist with a specific kernel configuration and hotplug operations. For example: Configure the kernel with CONFIG_SPARSEMEM and !CONFIG_SPARSEMEM_VMEMMAP. Then, hotplug add memory for the area where the gigantic page will be allocated. Zi Yan outlined steps to reproduce here [1].

[PATCH] thermal: cpufreq_cooling: freq_qos_update_request() returns < 0 on error

by Viresh Kumar

freq_qos_update_request() returns 1 if the effective constraint value has changed, 0 if the effective constraint value has not changed, or a negative error code on failures. The frequency constraints for CPUs can be set by different parts of the kernel. If the maximum frequency constraint set by other parts of the kernel are set at a lower value than the one corresponding to cooling state 0, then we will never be able to cool down the system as freq_qos_update_request() will keep on returning 0 and we will skip updating cpufreq_state and thermal pressure. Fix that by doing the updates even in the case where freq_qos_update_request() returns 0, as we have effectively set the constraint to a new value even if the consolidated value of the actual constraint is unchanged because of external factors.
