After starting to install the EC address space handler at the ACPI
namespace root, if there is an "orphan" _REG method in the EC device's
scope, it will not be evaluated any more. This breaks EC operation
regions on some systems, like Asus gu605.
To address this, use a wrapper around an existing ACPICA function to
look for an "orphan" _REG method in the EC device scope and evaluate
it if present.

This is a re-commit of
da05b143a308 ("x86/boot: Don't add the EFI stub to targets")
after the tagged patch incorrectly reverted it.
vmlinux-objs-y is added to targets, with an assumption that they are all
relative to $(obj); adding a $(objtree)/drivers/... path causes the
build to incorrectly create a useless
arch/x86/boot/compressed/drivers/... directory tree.
Fix this just by using a different make variable for the EFI stub.

net: bridge: mst: fix suspicious rcu usage warning
This set fixes a suspicious RCU usage warning triggered by syzbot[1] in
the bridge's MST code. After I converted br_mst_set_state to RCU, I
forgot to update the vlan group dereference helper. Fix it by using
the proper helper, in order to do that we need to pass the vlan group
which is already obtained correctly by the callers for their respective
context. Patch 01 is a requirement for the fix in patch 02.
Note I did consider rcu_dereference_rtnl() but the churn is much bigger
and in every part of the bridge. We can do that as a cleanup in
net-next.

The net.ipv6.route.flush system parameter takes a value which specifies
a delay used during the flush operation for aging exception routes. The
written value is however not used in the currently requested flush and
instead utilized only in the next one.
A problem is that ipv6_sysctl_rtcache_flush() first reads the old value
of net->ipv6.sysctl.flush_delay into a local delay variable and then
calls proc_dointvec() which actually updates the sysctl based on the
provided input.
Fix the problem by switching the order of the two operations.

In order to improve performance of typical scenarios we can try to insert
the entire vma on fault. This accelerates typical cases, such as when
the MMIO region is DMA mapped by QEMU. The vfio_iommu_type1 driver will
fault in the entire DMA mapped range through fixup_user_fault().
In synthetic testing, this improves the time required to walk a PCI BAR
mapping from userspace by roughly 1/3rd.
This is likely an interim solution until vmf_insert_pfn_{pmd,pud}() gain
support for pfnmaps.

Friedrich Weber reported a kernel crash problem and bisected to commit
81ada09cc25e ("blk-flush: reuse rq queuelist in flush state machine").
The root cause is that we use "list_move_tail(&rq->queuelist, pending)"
in the PREFLUSH/POSTFLUSH sequences. But rq->queuelist.next == xxx since
it's popped out from plug->cached_rq in __blk_mq_alloc_requests_batch().
We don't initialize its queuelist just for this first request, although
the queuelist of all later popped requests will be initialized.
Fix it by changing to use "list_add_tail(&rq->queuelist, pending)" so
rq->queuelist doesn't need to be initialized. It should be ok since rq
can't be on any list when PREFLUSH or POSTFLUSH, has no move actually.
Please note the commit 81ada09cc25e ("blk-flush: reuse rq queuelist in
flush state machine") also has another requirement that no drivers would
touch rq->queuelist after blk_mq_end_request() since we will reuse it to
add rq to the post-flush pending list in POSTFLUSH. If this is not true,
we will have to revert that commit IMHO.
This updated version adds "list_del_init(&rq->queuelist)" in flush rq
callback since the dm layer may submit request of a weird invalid format
(REQ_FSEQ_PREFLUSH | REQ_FSEQ_POSTFLUSH), which causes double list_add
if without this "list_del_init(&rq->queuelist)". The weird invalid format
problem should be fixed in dm layer.

For zoned block devices using zone write plugging, an rcu_barrier() call
is needed in disk_free_zone_resources() to synchronize freeing of zone
write plugs and the destrution of the mempool used to allocate the
plugs. The barrier call does slow down a little teardown of zoned block
devices but should not affect teardown of regular block devices or zoned
block devices that do not use zone write plugging (e.g. zoned DM devices
that do not require zone append emulation).
Modify disk_free_zone_resources() to return early if we do not have a
mempool to start with, that is, if the device does not use zone write
plugging. This avoids the costly rcu_barrier() and speeds up disk
teardown.

Enable PCIe0 and PCIe1 instances of PCIe in Root Complex mode of
operation on J784S4 EVM. The lanes of PCIe0 are connected to Serdes1
instance of Serdes while the lanes of PCIe1 are connected to Serdes0
instance of Serdes in J784S4 SoC. Despite both PCIe instances supporting
up to 4 Lanes, since the physical connections to the PCIe connector
corresponding to the PCIe1 instance of PCIe are limited to 2 Lanes on
the J784S4 EVM, update the "num-lanes" property of PCIe1 accordingly.

the CTRLMMR_MAC_IDx registers within the CTRL_MMR space. Assign the
compatible "ti,am62p-cpsw-mac-efuse" to enable "syscon_regmap" operations
on these registers. The MAC Address programmed in the eFuse is accessible
through the CTRLMMR_MAC_IDx registers. The "ti,syscon-efuse" device-tree
property points to the CTRLMMR_MAC_IDx registers, allowing the CPSW driver
to fetch the MAC Address and assign it to the network interface associated

1.4 GHz
The am625 is capable of running at 1.4 GHz when VDD_CORE is increased
from 0.75V to 0.85V. Increasing the voltage while the AM625 is
running has not been validated by TI, so we provide an overlay so that
people may choose to run at 1.4 GHz if they need the additional
performance.

A PRU system event "vring" has been added to each PRU and RTU
node in each of the ICSSG0, ICSSG1 and ICSSG2 remote processor
subsystems to enable the virtio/rpmsg communication between MPU
and that PRU/RTU core. The additions are done in the base
k3-am65-main.dtsi, and so are inherited by all the K3 AM65x
boards.
The PRU system events is the preferred approach over using TI
mailboxes, as it eliminates an external peripheral access from
the PRU/RTU-side, and keeps the interrupt generation internal to
the ICSSG. The difference from MPU would be minimal in using one
versus the other.
Mailboxes can still be used if desired, but currently there is
no support on firmware-side for K3 SoCs to use mailboxes. Either
approach would require that an appropriate firmware image is
loaded/booted on the PRU.
