+thermal-zones: cpu-thermal:trips:cpu-alert0:temperature:0:0: 850000 is greater than the maximum of 200000

+Subject: of: Fix reserved-memory overlap detection
+
+From: Vincent Whitchurch <vincent.whitchurch@axis.com>
+
+[ Upstream commit ca05f33316559a04867295dd49f85aeedbfd6bfd ]
+
+The reserved-memory overlap detection code fails to detect overlaps if
+either of the regions starts at address 0x0. The code explicitly checks
+for and ignores such regions, apparently in order to ignore dynamically
+allocated regions which have an address of 0x0 at this point. These
+dynamically allocated regions also have a size of 0x0 at this point, so
+fix this by removing the check and sorting the dynamically allocated
+regions ahead of any static regions at address 0x0.
+
+For example, there are two overlaps in this case but they are not
+currently reported:
+
+ foo@0 {
+ reg = <0x0 0x2000>;
+ };
+
+ bar@0 {
+ reg = <0x0 0x1000>;
+ };
+
+ baz@1000 {
+ reg = <0x1000 0x1000>;
+ };
+
+ quux {
+ size = <0x1000>;
+ };
+
+but they are after this patch:
+
+ OF: reserved mem: OVERLAP DETECTED!
+ bar@0 (0x00000000--0x00001000) overlaps with foo@0 (0x00000000--0x00002000)
+ OF: reserved mem: OVERLAP DETECTED!
+ foo@0 (0x00000000--0x00002000) overlaps with baz@1000 (0x00001000--0x00002000)

+Subject: scsi: core: Don't start concurrent async scan on same host
+
+From: Ming Lei <ming.lei@redhat.com>
+
+[ Upstream commit 831e3405c2a344018a18fcc2665acc5a38c3a707 ]
+
+The current scanning mechanism is supposed to fall back to a synchronous
+host scan if an asynchronous scan is in progress. However, this rule isn't
+strictly respected, scsi_prep_async_scan() doesn't hold scan_mutex when
+checking shost->async_scan. When scsi_scan_host() is called concurrently,
+two async scans on same host can be started and a hang in do_scan_async()
+is observed.
+
+Fixes this issue by checking & setting shost->async_scan atomically with
+shost->scan_mutex.

+Subject: vsock: use ns_capable_noaudit() on socket create
+
+From: Jeff Vander Stoep <jeffv@google.com>
+
+[ Upstream commit af545bb5ee53f5261db631db2ac4cde54038bdaf ]
+
+During __vsock_create() CAP_NET_ADMIN is used to determine if the
+vsock_sock->trusted should be set to true. This value is used later
+for determing if a remote connection should be allowed to connect
+to a restricted VM. Unfortunately, if the caller doesn't have
+CAP_NET_ADMIN, an audit message such as an selinux denial is
+generated even if the caller does not want a trusted socket.
+
+Logging errors on success is confusing. To avoid this, switch the
+capable(CAP_NET_ADMIN) check to the noaudit version.

+Subject: x86/kexec: Use up-to-dated screen_info copy to fill boot params
+
+From: Kairui Song <kasong@redhat.com>
+
+[ Upstream commit afc18069a2cb7ead5f86623a5f3d4ad6e21f940d ]
+
+kexec_file_load() currently reuses the old boot_params.screen_info,
+but if drivers have change the hardware state, boot_param.screen_info
+could contain invalid info.
+
+For example, the video type might be no longer VGA, or the frame buffer
+address might be changed. If the kexec kernel keeps using the old screen_info,
+kexec'ed kernel may attempt to write to an invalid framebuffer
+memory region.
+
+There are two screen_info instances globally available, boot_params.screen_info
+and screen_info. Later one is a copy, and is updated by drivers.
+
+So let kexec_file_load use the updated copy.
