There is an issue where the host is unable to tell the gadget what frame
rate it wants if the dwFrameIntervals in the interface descriptors are
not in ascending order. This means that when instantiating a uvc gadget
via configfs the user must make sure the dwFrameIntervals are in
ascending order.

Instead of silently failing the breaking of this rule, we sort the
dwFrameIntervals upon writing to configfs.

[ Upstream commit a2df0984e73fd9e1dad5fc3f1c307ec3de395e30 ]

It is good practice to make the setting of gpio-pinctrls explicitly in the
devicetree, and in this case even necessary.
Rockchip boards start with iomux settings set to gpio for most pins and
while the linux pinctrl driver also implicitly sets the gpio function if
a pin is requested as gpio that is not necessarily true for other drivers.

The issue in question stems from uboot, where the sdmmc_pwr pin is set
to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage
loader. The regulator controlled by the pin is active-low though, so
when the dwmmc hw-block sets its enabled bit, it actually disables the
regulator. By changing the pin back to gpio we fix that behaviour.

I spent some more time digging in this time, and think I have a better
fix, bailing out of the function that either initializes or errors
out here, which simplifies the code enough for gcc to figure out
what is going on. The earlier partial workaround can be removed now,
as the new workaround is better.

Up until now, mlxsw tolerated firmware versions that weren't exactly
matching the required version, if the branch number matched. That
allowed the users to test various firmware versions as long as they were
on the right branch.

On the other hand, it made it impossible for mlxsw to put a hard lower
bound on a version that fixes all problems known to date. If a user had
a somewhat older FW version installed, mlxsw would start up just fine,
possibly performing non-optimally as it would use features that trigger
problematic behavior.

Therefore tweak the check to accept any FW version that is:

- on the same branch as the preferred version, and
- the same as or newer than the preferred version.

The microSD card slot in the Sapphire board is not working because of
several issues:
 1.- The vmmc power supply is missing in the DTS. It is capable of 3.0V
 and has a GPIO-based enable control.
 2.- The vqmmc power supply can provide up to 3.3V, but it is capped in
 the DTS to just 3.0V because of the vmmc capability. This results in a
 conflict from the mmc driver requesting an unsupportable voltage range
 from 3.3V to 3.0V (min > max) as reported in dmesg. So, extend the
 range up to 3.3V. The hw should be able to stand this 0.3V tolerance.
 See mmc_regulator_set_vqmmc in drivers/mmc/core/core.c.
 3.- The card detect signal is non-working. There is a known conflict
 with jtag, but the workaround in drivers/soc/rockchip/grf.c does not
 work. Adding the broken-cd attribute to the DTS fixes the issue.

Presently we check first if CPUID is enabled. If it is not already
enabled, then we next call identify_cpu_without_cpuid() and clear
X86_FEATURE_CPUID.

Unfortunately, identify_cpu_without_cpuid() is the function where CPUID
becomes _enabled_ on Cyrix 6x86/6x86L CPUs.

Reverse the calling sequence so that CPUID is first enabled, and then
check a second time to see if the feature has now been activated.

There are comments in processor-cyrix.h advising you to _not_ make calls
using the deprecated macros in this style:

  setCx86_old(CX86_CCR4, getCx86_old(CX86_CCR4) | 0x80);

This is because it expands the macro into a non-functioning calling
sequence. The calling order must be:

  outb(CX86_CCR2, 0x22);
  inb(0x23);

From the comments:

 * When using the old macros a line like
 *   setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
 * gets expanded to:
 *  do {
 *    outb((CX86_CCR2), 0x22);
 *    outb((({
 *        outb((CX86_CCR2), 0x22);
 *        inb(0x23);
 *    }) | 0x88), 0x23);
 *  } while (0);

The new macros fix this problem, so use them instead.

In commit 9f480fae ("crypto: chacha20 - Fix keystream alignment for
chacha20_block()"), I had missed that chacha20_block() can be called
directly on the buffer passed to get_random_bytes(), which can have any
alignment.  So, while my commit didn't break anything, it didn't fully
solve the alignment problems.

Revert my solution and just update chacha20_block() to use
put_unaligned_le32(), so the output buffer need not be aligned.
This is simpler, and on many CPUs it's the same speed.

But, I kept the 'tmp' buffers in extract_crng_user() and
_get_random_bytes() 4-byte aligned, since that alignment is actually
needed for _crng_backtrack_protect() too.

Step to reproduce this bug:
1. logon as root
2. mount -t f2fs /dev/sdd /mnt;
3. touch /mnt/file;
4. chown system /mnt/file; chgrp system /mnt/file;
5. xfs_io -f /mnt/file -c "fsync";
6. godown /mnt;
7. umount /mnt;
8. mount -t f2fs /dev/sdd /mnt;

After step 8) we will expect file's uid/gid are all system, but during
recovery, these two fields were not been recovered, fix it.

[ Upstream commit c29de84149aba5f74e87b6491c13ac7203c12f55 ]

The PCI port driver saves the PCI state after initializing the device with
the applicable service devices.  This was, however, before the service
drivers were even registered because PCI probe happens before the
device_initcall initialized those service drivers.  The config space state
that the services set up were not being saved.  The end result would cause
PCI devices to not react to events that the drivers think they did if the
PCI state ever needed to be restored.

Fix this by changing the service drivers from using the init calls to
having the portdrv driver calling the services directly.  This will get the
state saved as desired, while making the relationship between the port
driver and the services under it more explicit in the code.
