This patch (as1615) fixes a bug in the Garmin USB serial driver. It
uses attach, disconnect, and release routines to carry out actions
that should be handled by port_probe and port_remove routines, because
they access port-specific data.
The bug causes an oops when the device in unplugged, because the
private data for each port structure now gets erased when the port is
unbound from the driver, resulting in a null-pointer dereference.

Fix port-data memory leak by allocating and freeing port data in
port_probe/remove rather than in attach/release, and by introducing
serial private data to store the device type which is interface rather
than port specific.
Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer freed at release.

Fix port data memory leak by replacing port private data with serial
private data.
Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer freed at
release.
The private data is used to store the control interface number, but as
this is the same for all ports on an interface it should be stored as
usb-serial data anyway.

This undoes commit 20f4665 "ARM: tegra: remove tegra_timer from
tegra_list_clks" by bringing back the tegra_timer clock. tegra_timer is
indeed a clock (hidden by the PERIPH_CLK macro) which should be added
to the tegra_list_clks.
The above commit caused tegra_init_timer() failing to get the clk
reference.

Commit 9e3c0066 (ARM: dts: imx6q-arm2: add pinctrl for uart and enet)
defines NANDF_CS pins as gpio in 'hog', assuming these two pins are
always used by usdhc3 in gpio mode as card-detection and
write-protection on ARM2 board. But it's not true. These pins are
shared by usdhc3 and gpmi-nand. We should have the pins functional
for gpmi-nand when usdhc3 is disabled.
Move the pins out of 'hog', so that pins only work in gpio mode as CD
and WP when usdhc3 is enabled, and otherwise they are available for
gpmi-nand.

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.

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.

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.

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.

The STOTG04 is an replacement for ISP1301.
Most of the registers on STOTG04 are the same as on ISP1301, but the
register ISP1301_I2C_OTG_CONTROL_2 (address 0x10) doesn't exist on the
ST part.
This is a work around for this by using the interrupt source register that
should behave the same on both parts and has the needed information.

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.

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.
