Changbin Du 25f69c69bc perf stat: Fix counting when initial delay configured
When creating counters with initial delay configured, the enable_on_exec
field is not set. So we need to enable the counters later. The problem
is, when a workload is specified the target__none() is true. So we also
need to check stat_config.initial_delay.

In this change, we add a new field 'initial_delay' for struct target
which could be shared by other subcommands. And define
target__enable_on_exec() which returns whether enable_on_exec should be
set on normal cases.

Before this fix the event is not counted:

  $ ./perf stat -e instructions -D 100 sleep 2
  Events disabled
  Events enabled

   Performance counter stats for 'sleep 2':

       <not counted>      instructions

         1.901661124 seconds time elapsed

         0.001602000 seconds user
         0.000000000 seconds sys

After fix it works:

  $ ./perf stat -e instructions -D 100 sleep 2
  Events disabled
  Events enabled

   Performance counter stats for 'sleep 2':

             404,214      instructions

         1.901743475 seconds time elapsed

         0.001617000 seconds user
         0.000000000 seconds sys

Arnaldo Carvalho de Melo a98c0710b4 tools headers svm: Sync svm headers with the kernel sources
To pick the changes in:

  8c29f01654 ("x86/sev: Add SEV-SNP guest feature negotiation support")

That triggers:

  CC      /tmp/build/perf-tools/arch/x86/util/kvm-stat.o
  CC      /tmp/build/perf-tools/util/header.o
  LD      /tmp/build/perf-tools/arch/x86/util/perf-in.o

  LD      /tmp/build/perf-tools/perf-in.o
  LINK    /tmp/build/perf-tools/perf

But this time causes no changes in tooling results, as the introduced
SVM_VMGEXIT_TERM_REQUEST exit reason wasn't added to SVM_EXIT_REASONS,
that is used in kvm-stat.c.

And addresses this perf build warning:

Linus Torvalds 857f1268a5 Changes in this cycle were:
- Shrink 'struct instruction', to improve objtool performance & memory
    footprint.
 
  - Other maximum memory usage reductions - this makes the build both faster,
    and fixes kernel build OOM failures on allyesconfig and similar configs
    when they try to build the final (large) vmlinux.o.
 
  - Fix ORC unwinding when a kprobe (INT3) is set on a stack-modifying
    single-byte instruction (PUSH/POP or LEAVE). This requires the
    extension of the ORC metadata structure with a 'signal' field.
 
  - Misc fixes & cleanups.

Al Viro caa82ae7ef openrisc: fix livelock in uaccess
openrisc equivalent of 26178ec11e "x86: mm: consolidate VM_FAULT_RETRY handling"
If e.g. get_user() triggers a page fault and a fatal signal is caught, we might
end up with handle_mm_fault() returning VM_FAULT_RETRY and not doing anything
to page tables.  In such case we must *not* return to the faulting insn -
that would repeat the entire thing without making any progress; what we need
instead is to treat that as failed (user) memory access.

nios2 equivalent of 26178ec11e "x86: mm: consolidate VM_FAULT_RETRY handling"
If e.g. get_user() triggers a page fault and a fatal signal is caught, we might
end up with handle_mm_fault() returning VM_FAULT_RETRY and not doing anything
to page tables.  In such case we must *not* return to the faulting insn -

instead is to treat that as failed (user) memory access.

Linus Torvalds 7c2bc4ed27 Driver core fixes for 6.3-rc1
Here is another small set of driver core patches for 6.3-rc1
 
 They resolve some reported problems with the previous driver core
 patches that are in your tree.
 
 They solve a problem with the bus_type cleanup as reported and fixced by
 Geert, and 2 fw_devlink changes to make debugging problems easier.
 There is one known outstanding problem with the fw_deflink changes in
 your tree that is still being worked on, and it looks like a clk core
 change will be submitted soon for that, probably after 6.3-rc1.
 
 All 3 of these have been in linux-next with no reported problems (only
 reports that they fixed problems.)

Thomas Gleixner 0fb7fb7134 genirq/msi, platform-msi: Ensure that MSI descriptors are unreferenced
Miquel reported a warning in the MSI core which is triggered when
interrupts are freed via platform_msi_device_domain_free().

This code got reworked to use core functions for freeing the MSI
descriptors, but nothing took care to clear the msi_desc->irq entry, which
then triggers the warning in msi_free_msi_desc() which uses desc->irq to
validate that the descriptor has been torn down. The same issue exists in
msi_domain_populate_irqs().

Up to the point that msi_free_msi_descs() grew a warning for this case,
this went un-noticed.

Provide the counterpart of msi_domain_populate_irqs() and invoke it in
platform_msi_device_domain_free() before freeing the interrupts and MSI
descriptors and also in the error path of msi_domain_populate_irqs().

Vasily Gorbik cd57953936 s390/kprobes: fix current_kprobe never cleared after kprobes reenter
Recent test_kprobe_missed kprobes kunit test uncovers the following
problem. Once kprobe is triggered from another kprobe (kprobe reenter),
all future kprobes on this cpu are considered as kprobe reenter, thus
pre_handler and post_handler are not being called and kprobes are counted
as "missed".

Commit b9599798f9 ("[S390] kprobes: activation and deactivation")
introduced a simpler scheme for kprobes (de)activation and status
tracking by using push_kprobe/pop_kprobe, which supposed to work for
both initial kprobe entry as well as kprobe reentry and helps to avoid
handling those two cases differently. The problem is that a sequence of
calls in case of kprobes reenter:
push_kprobe() <- NULL (current_kprobe)
push_kprobe() <- kprobe1 (current_kprobe)
pop_kprobe() -> kprobe1 (current_kprobe)
pop_kprobe() -> kprobe1 (current_kprobe)
leaves "kprobe1" as "current_kprobe" on this cpu, instead of setting it
to NULL. In fact push_kprobe/pop_kprobe can only store a single state
(there is just one prev_kprobe in kprobe_ctlblk). Which is a hack but
sufficient, there is no need to have another prev_kprobe just to store
NULL. To make a simple and backportable fix simply reset "prev_kprobe"
when kprobe is poped from this "stack". No need to worry about
"kprobe_status" in this case, because its value is only checked when
current_kprobe != NULL.

 [<00000003e60ccada>] ret_from_fork+0xa/0x40

The reason for this error report is that kprobes handling code failed
to restore irqs.

The problem is that when kprobe is triggered from another kprobe
post_handler current sequence of enable_singlestep / disable_singlestep
is the following:
enable_singlestep  <- original kprobe (saves kprobe_saved_imask)
enable_singlestep  <- kprobe triggered from post_handler (clobbers kprobe_saved_imask)
disable_singlestep <- kprobe triggered from post_handler (restores kprobe_saved_imask)
disable_singlestep <- original kprobe (restores wrong clobbered kprobe_saved_imask)

There is just one kprobe_ctlblk per cpu and both calls saves and
loads irq mask to kprobe_saved_imask. To fix the problem simply move
resume_execution (which calls disable_singlestep) before calling
post_handler. This also fixes the problem that post_handler is called
with pt_regs which were not yet adjusted after single-stepping.

Brian Vazquez 5c1ebbfabc net: use indirect calls helpers for sk_exit_memory_pressure()
Florian reported a regression and sent a patch with the following
changelog:

<quote>
 There is a noticeable tcp performance regression (loopback or cross-netns),
 seen with iperf3 -Z (sendfile mode) when generic retpolines are needed.

 With SK_RECLAIM_THRESHOLD checks gone number of calls to enter/leave
 memory pressure happen much more often. For TCP indirect calls are
 used.

 We can't remove the if-set-return short-circuit check in
 tcp_enter_memory_pressure because there are callers other than
 sk_enter_memory_pressure.  Doing a check in the sk wrapper too
 reduces the indirect calls enough to recover some performance.

 Before,
 0.00-60.00  sec   322 GBytes  46.1 Gbits/sec                  receiver

 After:

 "iperf3 -c $peer -t 60 -Z -f g", connected via veth in another netns.

had for years, lets do this instead.

The single difference between returning 0 and returning an error code in

emits a warning about the error being ignored.

at91wdt_remove() already emits a warning in the error case, so suppress
the more generic (and less helpful) one by returning 0.

Jakub Kicinski f3221361dc net: tls: avoid hanging tasks on the tx_lock
syzbot sent a hung task report and Eric explains that adversarial
receiver may keep RWIN at 0 for a long time, so we are not guaranteed
to make forward progress. Thread which took tx_lock and went to sleep
may not release tx_lock for hours. Use interruptible sleep where
possible and reschedule the work if it can't take the lock.

Testing: existing selftest passes

Harry Wentland c76e483cd9 drm/amd/display: Don't restrict bpc to 8 bpc
This will let us pass the kms_hdr.bpc_switch IGT
test.

The reason the bpc restriction was required is
historical. At one point in time we were not falling
back to a lower bpc when we didn't have enough
bandwidth for the maximum bpc reported by a display.
This meant that we couldn't enable some high refresh
modes unless we limitted the bpc.

Starting with this patch the issue is fixed:
commit cbd14ae7ea ("drm/amd/display: Fix
incorrectly pruned modes with deep color")

This patch implemented a fallback mechanism if mode
validation failed at the max bpc. This means users
now automatically get all modes that can be supported
by at least 6 bpc. The driver will enable the mode
with the highest possible bpc that is supported by
the display.

v2:
 - explain why this is no longer needed (Michel)
 - refer to commit that fixed bpc fallback (Michel)

Apple iMac11,2 (mid 2010) also with Radeon HD-4670 that has the same
issue as iMac10,1 (late 2009) where the internal eDP panel stays dark on

so the eDP panel stays active.

Additional steps:
Kernel boot parameter radeon.nomodeset=0 required to keep the eDP
panel active.
