[Why]
If DMUB is used, LVTMA VBIOS call can be used to control eDP instead of
tranditional transmitter control. Interface is agreed with VBIOS for
eDP to use this new path to program LVTMA registers.
[How]
Create DAL interface to send DMUB command for LVTMA as currently
implemented in VBIOS.

Every iteration of for_each_available_child_of_node() decrements
reference count of the previous node, however when control
is transferred from the middle of the loop, as in the case of
a return or break or goto, there is no decrement thus ultimately
resulting in a memory leak.

Remote source MAC addresses can be set on a 'source mode' macvlan

tightens the validation of these MAC addresses to match the validation

iproute2 uses IFLA_MACVLAN_MACADDR_DATA for its 'macvlan macaddr set'

arch/ia64: Restore arch-specific pgd_offset_k implementation
Recently we found regression when running will_it_scale/page_fault3 test
on ARM64. Over 70% down for the multi processes cases and over 20% down
for the multi threads cases. It turns out the regression is caused by
commit 89b15332af ("mm: drop mmap_sem before calling
balance_dirty_pages() in write fault").
The test mmaps a memory size file then write to the mapping, this would
make all memory dirty and trigger dirty pages throttle, that upstream
commit would release mmap_sem then retry the page fault. The retried
page fault would see correct PTEs installed then just fall through to
spurious TLB flush. The regression is caused by the excessive spurious
TLB flush. It is fine on x86 since x86's spurious TLB flush is no-op.
We could just skip the spurious TLB flush to mitigate the regression.

It might be better to adjust the code in two places:
1. Determine whether grp is currupt or not should be placed first.
2. (cr<=2 && free <ac->ac_g_ex.fe_len)should may belong to the crx
strategy, and it may be more appropriate to put it in the
subsequent switch statement block. For cr1, cr2, the conditions
in switch potentially realize the above judgment. For cr0, we
should add (free <ac->ac_g_ex.fe_len) judgment, and then delete
(free / fragments) >= ac->ac_g_ex.fe_len), because cr0 returns

The latter trace is due to the following sequence:
page_alloc_cpu_dead
drain_pages
drain_pages_zone
free_pcppages_bulk
where drain_pages() in this case is called under the assumption that
the unplugged cpu is no longer executing. To ensure that is the case,
and early call is made to __cpu_die()->pseries_cpu_die(), which runs a
loop that waits for the cpu to reach a halted state by polling its
status via query-cpu-stopped-state RTAS calls. It only polls for 25
iterations before giving up, however, and in the trace above this
results in the following being printed only .1 seconds after the
hotplug worker thread begins processing the unplug request:
pseries-hotplug-cpu: Attempting to remove CPU <NULL>, drc index: 1000013a
Querying DEAD? cpu 314 (314) shows 2
At that point the worker thread assumes the unplugged CPU is in some
unknown/dead state and procedes with the cleanup, causing the race
with the XIVE cleanup code executed by the unplugged CPU.
Fix this by waiting indefinitely, but also making an effort to avoid
spurious lockup messages by allowing for rescheduling after polling
the CPU status and printing a warning if we wait for longer than 120s.

qla_nvme_register_hba() puts out a warning when there are not enough queue
pairs available for FC-NVME. Just fail the NVME registration rather than a
WARNING + call Trace.

Multipath errors were seen during failback due to login timeout. The
remote device sent LOGO, the local host tore down the session and did
relogin. The RSCN arrived indicates remote device is going through failover
after which the relogin is in a 20s timeout phase. At this point the
driver is stuck in the relogin process. Add a fix to delete the session as
part of abort/flush the login.
