743df75ff1 tools lib traceevent: Fix missed freeing of subargs in free_arg() in filter
Some of args were missed in free_args(), as well as subargs.

That is args like FILTER_ARG_NUM have left and right pointers to other
args that also need to be freed.

101782ea2c lib tools traceevent: Add back pevent assignment in __pevent_parse_format()
Even though with the change of commit commit 2b29175 "tools lib
traceevent: Carve out events format parsing routine", allowed
__pevent_parse_format() to parse an event without the need of a pevent
handler, the event still needs to assign the pevent handed to it.

There's no problem with assigning it if the pevent is NULL, as the
event->pevent would be NULL without the assignment. But function parsing
handlers may be assigned to the pevent handler to help in parsing the
event. If there's no pevent then there would not be any function
handlers, but if the pevent isn't assigned first before parsing the
event, it wont honor the function handlers that were assigned.

Worse yet, the current code crashes if an event has a function that it
tries to parse. For example:

 # perf record -e scsi:scsi_dispatch_cmd_timeout
 Segmentation fault (core dumped)

This happens because the scsi_dispatch_cmd_timeout event format has the following:

  scsi_trace_parse_cdb(p, __get_dynamic_array(cmnd), REC->cmd_len)

which hasn't been defined by the pevent code.

When using the srcline sort key with perf report, I see many lines of

ffe10c6f95 perf tools: Fix segfault when using srcline sort key
The srcline sort key is for grouping samples based on their source file
and line number.  It use addr2line tool to get the information but it
requires dso name.  It caused a segfault when a sample does not have the
name by dereferencing a NULL pointer.  Fix it by using raw ip addresses
for those samples.

20b279ddb3 perf: Require exclude_guest to use PEBS - kernel side enforcement
Intel PEBS in VT-x context uses the DS address as a guest linear
address, even though its programmed by the host as a host linear
address. This either results in guest memory corruption and or the
hardware faulting and 'crashing' the virtual machine.  Therefore we have
to disable PEBS on VT-x enter and re-enable on VT-x exit, enforcing a
strict exclude_guest.

This patch enforces exclude_guest kernel side.

1342798cc1 perf tool: Precise mode requires exclude_guest
Summary of events per Peter:

  "Intel PEBS in VT-x context uses the DS address as a guest linear address,
  even though its programmed by the host as a host linear address. This
  either results in guest memory corruption and or the hardware faulting and
  'crashing' the virtual machine.  Therefore we have to disable PEBS on VT-x
  enter and re-enable on VT-x exit, enforcing a strict exclude_guest.

  AMB IBS does work but doesn't currently support exclude_* at all,
  setting an exclude_* bit will make it fail."

This patch handles userspace perf command, setting the exclude_guest
attribute if precise mode is requested, but only if a user has not
specified a request for guest or host only profiling (G or H attribute).

Kernel side AMD currently ignores all exclude_* bits, so there is no impact
to existing IBS code paths. Robert Richter has a patch where IBS code will
return EINVAL if an exclude_* bit is set. When this goes in it means use
of :p on AMD with IBS will first fail with EINVAL (because exclude_guest
will be set). Then the existing fallback code within perf will unset
exclude_guest and try again. The second attempt will succeed if the CPU
supports IBS profiling.

Most of the registers on STOTG04 are the same as on ISP1301, but the

eed6187d9f drm/nouveau/pm: do not stop reclocking if failing to set the fan speed
With the introduction of fan management modes, fan may not be drivable.
We should allow reclocking nonetheless.

This return was stupid to begin with since it may have left the card
in an intermediate state (clocks corresponding to a perflvl and voltage
corresponding to another one). The reclocking code will need to be
rewritten in a near-future in order to provide a better error handling.

84ed30538b xtensa: copy_thread with CLONE_VM must not copy live parent AR windows
When doing a fork (new VM), the new task has a mirror image of the
parent's stack, so keeps the same live register windows etc.
However when doing a clone with CLONE_VM, keeping the same VM
(eg. when creating a new thread), the child starts afresh on a new
stack -- it cannot share any part of the parent stack.  It
especially cannot have the same live AR windows as the parent,
otherwise it will overwrite the parent stack on overflow, likely
causing corruption.  (and so it did...)

Effectively, the register windows need to be spilled.
Turns out it's much easier to simply not copy parent register
windows when CLONE_VM is set.

3e5bde8ef4 serial/8250_hp300: Missing 8250 register interface conversion bits
commit 2655a2c76f ("8250: use the 8250
register interface not the legacy one") forgot to fully switch one
instance of struct uart_port to struct uart_8250_port, causing the
following compile failure:

drivers/tty/serial/8250/8250_hp300.c: In function ‘hpdca_init_one’:
drivers/tty/serial/8250/8250_hp300.c:174: error: ‘uart’ undeclared (first use in this function)
drivers/tty/serial/8250/8250_hp300.c:174: error: (Each undeclared identifier is reported only once
drivers/tty/serial/8250/8250_hp300.c:174: error: for each function it appears in.)

This went unnoticed in -next, as CONFIG_HPDCA is not set to y by
allmodconfig.

3ce9e53e78 kbuild: Fix accidental revert in commit fe04ddf
Commit fe04ddf7c2 ("kbuild: Do not package /boot and /lib in make
tar-pkg") accidentally reverted two previous kbuild commits.  I don't
know what I was thinking.

This brings back changes made by commits 24cc7fb69a ("x86/kbuild:
archscripts depends on scripts_basic") and c1c1a59e37 ("firmware: fix
directory creation rule matching with make 3.80")

0829184711 drm/radeon: Don't destroy I2C Bus Rec in radeon_ext_tmds_enc_destroy().
radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.

c1a7ca0de3 drm/radeon/cayman: set VM max pfn at MC init
No need to emit them at VM flush as we no longer use
variable sized page tables now that we support 2 level
page tables.  This matches the behavior of SI (which
does not support variable sized page tables).

90a51a3292 drm/radeon: allocate page tables on demand v4
Based on Dmitries work, but splitting the code into page
directory and page table handling makes it far more
readable and (hopefully) more reliable.

Allocations of page tables are made from the SA on demand,
that should still work fine since all page tables are of
the same size.

Also using the fact that allocations from the SA are mostly
continuously (except for end of buffer wraps and under very
high memory pressure) to group updates send to the chipset
specific code into larger chunks.

v3: mostly a rewrite of Dmitries previous patch.
v4: fix some typos and coding style
