There are many situations where generic HID driver provides some basic level
of support for certain device, but later this support (usually by implementing
vendor-specific extensions of HID protocol) is extended and the support moved
over to a separate (usually per-vendor) specific driver.

This might bring a rather unpleasant suprise for users, as all of a sudden
there is a new config option they have to enable in order to get any support
for their device whatsoever, although previous kernel versions provided basic
support through the generic driver. Which is rightfully seen as a regression.

Fix this by including the entry for a particular device in
hid_have_special_driver[] iff the specific config option has been specified,
and let generic driver handle the device otherwise.
Also make the behavior of hid_scan_report() (where the same decision is being
taken on a per-report level) consistent.

While at it, reshuffle the hid_have_special_driver[] a bit to restore the
alphabetical ordering (first order by config option, and within those
sections order by VID).

This is considered a short-term solution, before generic way of giving
precedence to special drivers and falling back to generic driver is
figured out.

While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for
spotting this (and for discovering a few issues in the conversion).

Commit 27ed3cd2 (cpufreq: conservative: Fix the logic in frequency
decrease checking) removed the 10 point substraction when comparing the
load against down_threshold but did not remove the related limit for the
down_threshold value.  As a result, down_threshold lower than 11 is not
allowed even though values from 1 to 10 do work correctly too. The
comment ("cannot be lower than 11 otherwise freq will not fall") also
does not apply after removing the substraction.

For this reason, allow down_threshold to take any value from 1 to 99
and fix the related comment.

Considering this case:

 1. A program opens a sysfs table file 65535 times, it can increase
    validation_count and first increment cause the table to be mapped:

     validation_count = 65535

 2. AML execution causes "Load" to be executed on the same
    table, this time it cannot increase validation_count, so
    validation_count remains:

      validation_count = 65535

 3. The program closes sysfs table file 65535 times, it can decrease
    validation_count and the last decrement cause the table to be
    unmapped:

     validation_count = 0

 4. AML code still accessing the loaded table, kernel crash can be
    observed.

To prevent that from happening, add a validation_count threashold.
When it is reached, the validation_count can no longer be
incremented/decremented to invalidate the table descriptor (means
preventing table unmappings)

Note that code added in acpi_tb_put_table() is actually a no-op but
changes the warning message into a "warn once" one. Lv Zheng.

This is triggered by running both win7 and win2016 on L1 KVM simultaneously,
and then gives stress to memory on L1, I can observed this hang on L1 when
at least ~70% swap area is occupied on L0.

This is due to async pf was injected to L2 which should be injected to L1,
L2 guest starts receiving pagefault w/ bogus %cr2(apf token from the host
actually), and L1 guest starts accumulating tasks stuck in D state in
kvm_async_pf_task_wait() since missing PAGE_READY async_pfs.

This patch fixes the hang by doing async pf when executing L1 guest.
