Sstc extension allows the guest to program the vstimecmp CSR directly
instead of making an SBI call to the hypervisor to program the next
event. The timer interrupt is also directly injected to the guest by
the hardware in this case. To maintain backward compatibility, the
hypervisors also update the vstimecmp in an SBI set_time call if
the hardware supports it. Thus, the older kernels in guest also
take advantage of the sstc extension.

Commit 6f8191fdf41d ("block: simplify disk shutdown") removed the call
to blk_get_queue() during gendisk allocation but missed to remove the
corresponding cleanup code blk_put_queue() for it. Thus, if the gendisk
allocation fails, the request_queue refcount gets decremented and
reaches 0, causing blk_mq_release() to be called with a hctx still
alive. That triggers a WARNING report, as found by syzkaller:

XEN_SCRUB_PAGES_DEFAULT. As xen.config sets 'XEN_BALLOON=y' and
XEN_SCRUB_PAGES_DEFAULT defaults to yes, there is no further need to set
this config in the xen.config file.

This code tries to store -EFAULT in an unsigned int. The
xenbus_file_read() function returns type ssize_t so the negative value
is returned as a positive value to the user.
This change forces another change to the min() macro. Originally, the
min() macro used "unsigned" type which checkpatch complains about. Also
unsigned type would break if "len" were not capped at MAX_RW_COUNT. Use
size_t for the min(). (No effect on runtime for the min_t() change).

In some use cases[1], the backend is created while the frontend doesn't
support the persistent grants feature, but later the frontend can be
changed to support the feature and reconnect. In the past, 'blkback'
enabled the persistent grants feature since it unconditionally checked
if frontend supports the persistent grants feature for every connect
('connect_ring()') and decided whether it should use persistent grans or
not.
However, commit aac8a70db24b ("xen-blkback: add a parameter for
disabling of persistent grants") has mistakenly changed the behavior.
It made the frontend feature support check to not be repeated once it
shown the 'feature_persistent' as 'false', or the frontend doesn't
support persistent grants.
Similar behavioral change has made on 'blkfront' by commit 74a852479c68
("xen-blkfront: add a parameter for disabling of persistent grants").
This commit changes the behavior of the parameter to make effect for
every connect, so that the previous behavior of 'blkfront' can be
restored.

Persistent grants feature can be used only when both backend and the
frontend supports the feature. The feature was always supported by
'blkback', but commit aac8a70db24b ("xen-blkback: add a parameter for
disabling of persistent grants") has introduced a parameter for
disabling it runtime.
To avoid the parameter be updated while being used by 'blkback', the
commit caches the parameter into 'vbd->feature_gnt_persistent' in
'xen_vbd_create()', and then check if the guest also supports the
feature and finally updates the field in 'connect_ring()'.
However, 'connect_ring()' could be called before 'xen_vbd_create()', so
later execution of 'xen_vbd_create()' can wrongly overwrite 'true' to
'vbd->feature_gnt_persistent'. As a result, 'blkback' could try to use
'persistent grants' feature even if the guest doesn't support the
feature.
This commit fixes the issue by moving the parameter value caching to
'xen_blkif_alloc()', which allocates the 'blkif'. Because the struct
embeds 'vbd' object, which will be used by 'connect_ring()' later, this
should be called before 'connect_ring()' and therefore this should be
the right and safe place to do the caching.

Implement support for the HVMOP_set_evtchn_upcall_vector hypercall in
order to set the per-vCPU event channel vector callback on Linux and
use it in preference of HVM_PARAM_CALLBACK_IRQ.
If the per-VCPU vector setup is successful on BSP, use this method
for the APs. If not, fallback to the global vector-type callback.
Also register callback_irq at per-vCPU event channel setup to trick
toolstack to think the domain is enlightened.

1. Use common arch_stack_walk() infrastructure to avoid duplicated code
and avoid taking care of the stack storage and filtering.
2. Add sched_ra (means sched return address) and sched_cfa (means sched
call frame address) to thread_info, and store them in switch_to().
3. Add __get_wchan() implementation.
Now we can print the process stack and wait channel by cat /proc/*/stack
and /proc/*/wchan.

It unwind the stack frame based on prologue code analyze.
CONFIG_KALLSYMS is needed, at least the address and length
of each function.
Three stages when we do unwind,
1) unwind_start(), the prapare of unwinding, fill unwind_state.
2) unwind_done(), judge whether the unwind process is finished or not.
3) unwind_next_frame(), unwind the next frame.
Dividing unwinder helps to add new unwinders in the future, e.g.:
unwinder_frame, unwinder_orc, .etc.

Name "guess unwinder" comes from x86, it scans the stack and reports
every kernel text address it finds.
Unwinders can be used by dump_stack() and other stacktrace functions.
Three stages when we do unwind,
1) unwind_start(), the prapare of unwinding, fill unwind_state.
2) unwind_done(), judge whether the unwind process is finished or not.
3) unwind_next_frame(), unwind the next frame.
Add get_stack_info() to get stack info. At present we have irq stack and
task stack. The next_sp is the key info between two types of stacks.
Dividing unwinder helps to add new unwinders in the future.

The kernel entry points of both boot CPU (i.e., kernel_entry) and non-
boot CPUs (i.e., smpboot_entry) may be physical address from BootLoader
(in DA mode or identity-mapping PG mode). So we should jump to the link
address before PG enabled (because DA is disabled at the same time) and
just after DMW configured.
Specifically: With some older firmwares, non-boot CPUs started with PG

page table, which is deemed unnecessary. OTOH, latest firmware versions
configure the non-boot CPUs to start in DA mode, so kernel-side changes
are needed.

Solution is to send lease break ack immediately even in case of
deferred close handles to avoid lease break request timing out
and let deferred closed handle gets closed as scheduled.
Later patches could optimize cases where we then close some

Deferred close can be a very useful feature for allowing
caching data for read, and for minimizing the number of
reopens needed for a file that is repeatedly opened and
close but there are workloads where its default (1 second,
similar to actimeo/acregmax) is much too small.
Allow the user to configure the amount of time we can
defer sending the final smb3 close when we have a
handle lease on the file (rather than forcing it to depend
on value of actimeo which is often unrelated, and less safe).
Adds new mount parameter "closetimeo=" which is the maximum
number of seconds we can wait before sending an SMB3
close when we have a handle lease for it. Default value
also is set to slightly larger at 5 seconds (although some
other clients use larger default this should still help).

Since Arm64 arch doesn't support HITMs flags, this patch changes to use
'peer' as default display if user doesn't specify any type; for other
arches, it still uses 'tot' as default display type if user doesn't
specify it.
This patch changes to call perf_session__new() in an earlier place, so
session environment can be initialized ahead and arch info can be used
for setting display type.

peer snooping.
For displaying with option 'peer', the "Shared Data Cache Line Table"
and "Shared Cache Line Distribution Pareto" both sort with the metrics
"tot_peer".
As result, we can get the 'peer' display:

The display type is shown by combination the display string array and a
suffix string "HITMs", which is not friendly to extend display for other
sorting type (e.g. extension for peer operations).
This patch moves the suffix string "HITMs" into display string array for
HITM types, so it can allow us to not necessarily to output string
"HITMs" for new incoming display type.

The node header array contains 3 items, each item is used for one of
the 3 flavors for node accessing info. To extend sorting on other
snooping type and not always stick to HITMs, the second header string
"Node{cpus %hitms %stores}" should be adjusted (e.g. it's changed as
"Node{cpus %peer %stores}").
For this reason, this patch changes the node header array to three
flat variables and uses switch-case in function setup_nodes_header(),
thus it is easier for altering the header string.

Use more general naming for the main sort dimension, this can allow us
not to sort only on HITM snoop type, so it can be extended to support
other costly snooping operations. So rename the dimension to the prefix
'percent_costly_".

Perf c2c tool has an assumption that it heavily depends on HITM snoop
type to detect cache false sharing, unfortunately, HITM is not supported
on some architectures.
Essentially, perf c2c tool wants to find some very costly snooping
operations for false cache sharing, this means it's not necessarily
to stick using HITM tags and we can explore other snooping types
(e.g. SNOOPX_PEER).
For this reason, this patch renames HITM related display macros with
suffix '_HITM', so it can be distinct if later add more display types
for on other snooping type.
