[PATCH v2 3/6] drm/i915: Leave intel_conn->mst_port set, use mst_port_gone instead

by Lyude Paul

Currently we set intel_connector->mst_port to NULL to signify that the MST port has been removed from the system so that we can prevent further action on the port such as connector probes, mode probing, etc. However, we're going to need access to intel_connector->mst_port in order to fixup ->best_encoder() so that it can always return the correct encoder for an MST port to prevent legacy DPMS prop changes from failing. This should be safe, so instead keep intel_connector->mst_port always set and instead add intel_connector->mst_port_gone in order to signify whether or not the connector has disappeared from the system.

[PATCH AUTOSEL 4.9 01/34] binfmt_elf: Respect error return from `regset->active'

by Sasha Levin

From: "Maciej W. Rozycki" <macro(a)mips.com> [ Upstream commit 2f819db565e82e5f73cd42b39925098986693378 ] The regset API documented in <linux/regset.h> defines -ENODEV as the result of the `->active' handler to be used where the feature requested is not available on the hardware found. However code handling core file note generation in `fill_thread_core_info' interpretes any non-zero result from the `->active' handler as the regset requested being active. Consequently processing continues (and hopefully gracefully fails later on) rather than being abandoned right away for the regset requested. Fix the problem then by making the code proceed only if a positive result is returned from the `->active' handler. Signed-off-by: Maciej W.

[PATCH 4/4] Drivers: hv: vmbus: Use cpumask_var_t for on-stack cpu mask

From: Dexuan Cui <decui(a)microsoft.com> A cpumask structure on the stack can cause a warning with CONFIG_NR_CPUS=8192 (e.g. Ubuntu 16.04 and 18.04 use this): drivers/hv//channel_mgmt.c: In function ‘init_vp_index’: drivers/hv//channel_mgmt.c:702:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=] Nowadays it looks most distros enable CONFIG_CPUMASK_OFFSTACK=y, and hence we can work around the warning by using cpumask_var_t.

[PATCH 3/4] Drivers: hv: kvp: Fix two "this statement may fall through" warnings

by kys＠linuxonhyperv.com

From: Dexuan Cui <decui(a)microsoft.com> We don't need to call process_ib_ipinfo() if message->kvp_hdr.operation is KVP_OP_GET_IP_INFO in kvp_send_key(), because here we just need to pass on the op code from the host to the userspace; when the userspace returns the info requested by the host, we pass the info on to the host in kvp_respond_to_host() -> process_ob_ipinfo(). BTW, the current buggy code actually doesn't cause any harm, because only message->kvp_hdr.operation is used by the userspace, in the case of KVP_OP_GET_IP_INFO. The patch also adds a missing "break;" in kvp_send_key(). BTW, the current buggy code actually doesn't cause any harm, because in the case of KVP_OP_SET, the unexpected fall-through corrupts message->body.kvp_set.data.key_size, but that is not really used: see the definition of struct hv_kvp_exchg_msg_value.
