So it's unnecessary to check if the attached_sas_addr is zero. And although if the sas address is not changed, we always have to unregister the old device when we are going to register a new one.

BugLink: https://bugs.launchpad.net/bugs/1853881 [ Upstream commit 8dbf9c7a ] When USB requests for video data fail to be submitted, the driver signals a problem to the host by halting the video streaming endpoint. This is only valid in bulk mode, as isochronous transfers have no handshake phase and can't thus report a stall. The usb_ep_set_halt() call returns an error when using isochronous endpoints, which we happily ignore, but some UDCs complain in the kernel log. Fix this by only trying to halt the endpoint in bulk mode. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1853881 [ Upstream commit 03b099bd ] There are comments in processor-cyrix.h advising you to _not_ make calls using the deprecated macros in this style: setCx86_old(CX86_CCR4, getCx86_old(CX86_CCR4) | 0x80); This is because it expands the macro into a non-functioning calling sequence. The calling order must be: outb(CX86_CCR2, 0x22); inb(0x23); From the comments: * When using the old macros a line like * setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88); * gets expanded to: * do { * outb((CX86_CCR2), 0x22); * outb((({ * outb((CX86_CCR2), 0x22); * inb(0x23); * }) | 0x88), 0x23); * } while (0); The new macros fix this problem, so use them instead.

BugLink: https://bugs.launchpad.net/bugs/1853881 [ Upstream commit 85a88cab ] When performing partition migrations all present CPUs must be online as all present CPUs must make the H_JOIN call as part of the migration process. Once all present CPUs make the H_JOIN call, one CPU is returned to make the rtas call to perform the migration to the destination system. During testing of migration and changing the SMT state we have found instances where CPUs are offlined, as part of the SMT state change, before they make the H_JOIN call. This results in a hung system where every CPU is either in H_JOIN or offline. To prevent this this patch disables CPU hotplug during the migration process. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1853881 [ Upstream commit 4d19db77 ] Calling napi_schedule() from process context does not ensure that the NET_RX softirq is run in a timely fashion. So trigger it manually. This is no big issue with current code. A call to ndo_open() is usually followed by a ndo_set_rx_mode() call, and for qeth this contains a spin_unlock_bh(). Except for OSN, where qeth_l2_set_rx_mode() bails out early. Nevertheless it's best to not depend on this behaviour, and just fix the issue at its source like all other drivers do. For instance see commit 83a0c6e5 ("i40e: Invoke softirqs after napi_reschedule"). Fixes: a1c3ed4c ("qeth: NAPI support for l2 and l3 discipline") Signed-off-by:
