hid-asus depends on asus-wmi through the asus_wmi_evaluate_method. Before
this commit asus-wmi, and thus hid-asus, could not be loaded on non-Asus
systems. This breaks using Asus bluetooth keyboards such as the Asus
T100CHI keyboard with non Asus systems.

This commit fixes this by allowing asus-wmi to load on systems without the
Asus Management GUID.

This is safe to do since all asus-wmi sub drivers use
asus_wmi_register_driver which also checks for the GUID.

This commit also improves the error messages in asus_wmi_register_driver
to include "ASUS" in their description to make them more clear. This is
important since we now rely on those errors when loaded on systems without
the Asus Management GUID.

Recently introduced commit "platform/x86: intel_pmc_core: Show Latency
Tolerance info <51337cd94d18184601ac0fb4cf1a02b8bbabc3d7> skipped the
LTR from a reserved IP. Though this doesn't cause any functional issue
but it is needed for the consumers of "ltr_ignore" as the index printing
for "ltr_show" is missing. For example, w/o this change, a user that wants
to ignore LTR from ME would do something like

echo 5 > ltr_ignore

but the index for ME is 6. Printing a reserved IP helps to properly
calculate LTR ignore offsets.

A previous commit "platform/x86: intel_pmc_core: Make the driver PCH
family agnostic <c977b98b>" provided
better abstraction to this driver but has some fundamental issues.

e.g. the following condition

for (index = 0; index < pmcdev->map->ppfear_buckets &&
	index < PPFEAR_MAX_NUM_ENTRIES; index++, iter++)

is wrong because for CNL, PPFEAR_MAX_NUM_ENTRIES is hardcoded as 5 which
is _wrong_ and even though ppfear_buckets is 8, the loop fails to read
all eight registers needed for CNL PCH i.e. PPFEAR0 and PPFEAR1. This
patch refactors the pfear show logic to correctly read PCH IP power
gating status for Cannonlake and beyond.

BMC150 compatible accelerometer and a BMC150 compatible magnetometer.

The ACPI firmware node actually contains 3 I2cSerialBusV2 resources,

Power button suspend for some Dell models was added in:

commit 821b8536 ("platform/x86: intel-hid: Power button suspend on Dell Latitude 7275")

by checking against the power button press notification (0xCE) to report
the power button press event. The corresponding power button release
notification (0xCF) was caught and ignored to stop it from being reported
as an "unknown event" in the logs.

The missing button release event is creating issues on Android-x86, as
reported on the project mailing list for a Dell Latitude 5175 model, since
the events are expected in down/up pairs.

Report the power button release event to fix this issue.

GCC 9 reworks the way the references to the stack canary are
emitted, to prevent the value from being spilled to the stack
before the final comparison in the epilogue, defeating the
purpose, given that the spill slot is under control of the
attacker that we are protecting ourselves from.

Since our canary value address is obtained without accessing
memory (as opposed to pre-v7 code that will obtain it from a
literal pool), it is unlikely (although not guaranteed) that
the compiler will spill the canary value in the same way, so
let's just disable this improvement when building with GCC9+.

If an input number x for int_sqrt64() has the highest bit set, then
fls64(x) is 64.  (1UL << 64) is an overflow and breaks the algorithm.

Subtracting 1 is a better guess for the initial value of m anyway and
that's what also done in int_sqrt() implicitly [*].

[*] Note how int_sqrt() uses __fls() with two underscores, which already
    returns the proper raw bit number.

    In contrast, int_sqrt64() used fls64(), and that returns bit numbers
    illogically starting at 1, because of error handling for the "no
    bits set" case. Will points out that he bug probably is due to a
    copy-and-paste error from the regular int_sqrt() case.

Commit 594cc251 ("make 'user_access_begin()' do 'access_ok()'")
makes the access_ok() check part of the user_access_begin() preceding a
series of 'unsafe' accesses.  This has the desirable effect of ensuring
that all 'unsafe' accesses have been range-checked, without having to
pick through all of the callsites to verify whether the appropriate
checking has been made.

However, the consolidated range check does not inhibit speculation, so
it is still up to the caller to ensure that they are not susceptible to
any speculative side-channel attacks for user addresses that ultimately
fail the access_ok() check.

This is an oversight, so use __uaccess_begin_nospec() to ensure that
speculation is inhibited until the access_ok() check has passed.

The generated test constructs a packet with mac header, network
header, skb->data pointing to network header and skb->len 0.

Redirecting to a sit0 through __bpf_redirect_no_mac pulls the
mac length, even though skb->data already is at skb->network_header.
bpf_prog_test_run_skb has already pulled it as LWT_XMIT !is_l2.

Update the offset calculation to pull only if skb->data differs
from skb->network_header, which is not true in this case.

The test itself can be run only from commit 1cf1cae9 ("bpf:
introduce BPF_PROG_TEST_RUN command"), but the same type of packets
with skb at network header could already be built from lwt xmit hooks,
so this fix is more relevant to that commit.

Also set the mac header on redirect from LWT_XMIT, as even after this
change to __bpf_redirect_no_mac that field is expected to be set, but
is not yet in ip_finish_output2.

   introduced in v4.20.

 - Fix a regression in the behaviour of semctl/shmctl/msgctl IPC
   syscalls for kernels including n32 support but not o32 support caused
   by some cleanup in v3.19.

Pull libnvdimm fixes from Dan Williams:
 "A crash fix, a build warning fix, a miscellaneous small cleanups.

  In case anyone is looking for them, there was a regression caught by
  testing that caused two patches to be dropped from this update.  Those
  patches have been reworked and will soak for another week / re-target
  5.0-rc4.

   - Fix driver initialization crash due to the inability to report an
     'error' state for a DIMM's security capability.

   - Build warning fix for little-endian ARM64 builds

   - Fix a potential race between the EDAC driver's usage of the NFIT
     SMBIOS id for a DIMM and the driver shutdown path.

   - A small collection of one-line benign cleanups for duplicate
     variable assignments, a duplicate header include and a mis-typed
     function argument"
