The code in block/partitions/msdos.c recognizes FreeBSD, OpenBSD
and NetBSD partitions and does a reasonable job picking out OpenBSD
and NetBSD UFS subpartitions.
But for FreeBSD the subpartitions are always "bad".
Kernel: <bsd:bad subpartition - ignored
Though all 3 of these BSD systems use UFS as a file system, only
FreeBSD uses relative start addresses in the subpartition
declarations.

Brought up by both Laurent and Andrzej when reviewing the new
->mode_valid hooks. Since mode_fixup is just a simpler version of the
much more generic atomic_check we can't really unify it with
mode_valid. Most drivers should probably switch their current
mode_fixup code to either the new mode_valid or the atomic_check
hooks, but e.g. that doesn't exist yet for bridges, and for CRTCs the
situation is a bit more complicated. Hence there's no clear
equivalence between mode_fixup and mode_valid, even if it looks like
that at first glance.

This adds a new callback to crtc, encoder and bridge helper functions
called mode_valid(). This callback shall be implemented if the
corresponding component has some sort of restriction in the modes
that can be displayed. A NULL callback implicates that the component
can display all the modes.
We also change the documentation so that the new and old callbacks
are correctly documented.
Only the callbacks were implemented to simplify review process,
following patches will make use of them.
Changes in v2 from Daniel:
- Update the warning about how modes aren't filtered in atomic_check -
the heleprs help out a lot more now.
- Consistenly roll out that warning, crtc/encoder's atomic_check
missed it.
- Sprinkle more links all over the place, so it's easier to see where
this stuff is used and how the differen hooks are related.
- Note that ->mode_valid is optional everywhere.
- Explain why the connector's mode_valid is special and does _not_ get
called in atomic_check.
v3: Document what can and cannot be checked in mode_valid a bit better

comparing the hard_header_len size of the current packet to the previous

When I introduced ptracer_cred I failed to consider the weirdness of
fork where the task_struct copies the old value by default. This
winds up leaving ptracer_cred set even when a process forks and
the child process does not wind up being ptraced.
Because ptracer_cred is not set on non-ptraced processes whose
parents were ptraced this has broken the ability of the enlightenment
window manager to start setuid children.
Fix this by properly initializing ptracer_cred in ptrace_init_task
This must be done with a little bit of care to preserve the current value
of ptracer_cred when ptrace carries through fork. Re-reading the
ptracer_cred from the ptracing process at this point is inconsistent
with how PT_PTRACE_CAP has been maintained all of these years.

The description of the connection between the dwmmc (SDIO) controller and
the Wifi chip, which is attached to the SDIO bus is wrong. Currently the
SDIO card can't be detected and thus the Wifi doesn't work.
Let's fix this by assigning the correct vmmc supply, which is the always on
regulator VDD_3V3 and remove the WLAN enable regulator altogether. Then to
properly deal with the power on/off sequence, add a mmc-pwrseq node to
describe the resources needed to detect the SDIO card.
Except for the WLAN enable GPIO and its corresponding assert/de-assert
delays, the mmc-pwrseq node also contains a handle to a clock provided by
the hi655x pmic. This clock is also needed to be able to turn on the WiFi
chip.

checks each pointer first ... While re-reading everything I also
realized that we must clean up the fb refcounts, and specifically
plane->old_fb before we drop the locks, either in the final unlocking,

- Fix RTC wakeup from suspend-to-idle broken by the recent rework
of ACPI wakeup handling (Rafael Wysocki).
- Update intel_pstate driver documentation to reflect the current
code and explain how it works in more detail (Rafael Wysocki).
- Fix an issue related to CPU idleness detection on systems with
shared cpufreq policies in the schedutil governor (Juri Lelli).

cpufreq: dbx500: add a Kconfig symbol
PM / hibernate: Declare variables as static
PowerCap: Fix an error code in powercap_register_zone()
RTC: rtc-cmos: Fix wakeup from suspend-to-idle

We need to initializes those variables to 0 for platforms that do not
provide ACPI parameters. Otherwise, we set sda_hold_time to random
values, breaking e.g. Galileo and IOT2000 boards.

The datasheet and application note does not mention an allowed range for
the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set
lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with
T5x06 touch.
So, lacking a known lower limit, we increase the range for thresholds,
and set the lower limit to 0. The documentation is updated accordingly.

Prior to the pstore interface refactoring, the "id" generated during
a backend pstore_write() was only retained by the internal pstore
inode tracking list. Additionally the "part" was ignored, so EFI
would encode this in the id. This corrects the misunderstandings
and correctly sets "id" during pstore_write(), and uses "part"
directly during pstore_erase().

Commit cc7b0d4955 ("PCI: designware: Update PCI config space remap
function") made PCI configuration requests non-posted, which means we now
get a synchronous abort when the CFG space read to probe for downstream
devices times out.
Synchronous aborts need to be handled differently from the async aborts we
were getting before, in particular the PC needs to be advanced when
resolving the abort. This is mostly a copy of what other PCI drivers do on
ARM to handle those aborts.

When a switch endpoint is configured without NTB, the mmio_ntb registers
will read all zeros. However, in corner case configurations where the
partition ID is not zero and NTB is not enabled, the code will have the
wrong partition ID and this causes the driver to use the wrong set of
drivers. To fix this we simply take the partition ID from the system info
region.
