9ddac734aa drm/vmwgfx: Improve on IOMMU detection
instead of relying on intel_iommu_enabled, use the fact that the
dma_map_ops::map_page != dma_direct_map_page.

4cbfa1e6c0 drm/vmwgfx: Fix setting of dma masks
Previously we set only the dma mask and not the coherent mask. Fix that.
Also, for clarity, make sure both are initially set to 64 bits.

728354c005 drm/vmwgfx: Return error code from vmw_execbuf_copy_fence_user
The function was unconditionally returning 0, and a caller would have to
rely on the returned fence pointer being NULL to detect errors. However,
the function vmw_execbuf_copy_fence_user() would expect a non-zero error
code in that case and would BUG otherwise.

So make sure we return a proper non-zero error code if the fence pointer
returned is NULL.

2b3cd6249b drm/vmwgfx: fix the check when to use dma_alloc_coherent
Since Linux 4.21 we merged the swiotlb ops into the DMA direct ops,
so they would always have a the sync_single methods.  But late in
the cicle we also removed the direct ops entirely, so we'd see NULL
DMA ops.  Switch vmw_dma_select_mode to only detect swiotlb presence
using swiotlb_nr_tbl() instead.

a3c5e2cd79 drm/msm: Fix A6XX support for opp-level
The bindings for Qualcomm opp levels changed after being Acked but
before landing.  Thus the code in the GPU driver that was relying on
the old bindings is now broken.

Let's change the code to match the new bindings by adjusting the old
string 'qcom,level' to the new string 'opp-level'.  See the patch
("dt-bindings: opp: Introduce opp-level bindings").

NOTE: we will do additional cleanup to totally remove the string from
the code and use the new dev_pm_opp_get_level() but we'll do it in a
future patch.  This will facilitate getting the important code fix in
sooner without having to deal with cross-maintainer dependencies.

This patch needs to land before the patch ("arm64: dts: sdm845: Add
gpu and gmu device nodes") since if a tree contains the device tree
patch but not this one you'll get a crash at bootup.

5631e8576a pstore/ram: Avoid allocation and leak of platform data
Yue Hu noticed that when parsing device tree the allocated platform data
was never freed. Since it's not used beyond the function scope, this
switches to using a stack variable instead.

2c88c742d0 gcc-plugins: arm_ssp_per_task_plugin: fix for GCC 9+
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+.

fbfaf85190 fix int_sqrt64() for very large numbers
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.

6e693b3ffe x86: uaccess: Inhibit speculation past access_ok() in user_access_begin()
Commit 594cc251fd ("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 1cf1cae963 ("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.

3e64cf7a43 net: phy: phy driver features are mandatory
Since phy driver features became a link_mode bitmap, phy drivers that
don't have a list of features configured will cause the kernel to crash
when probed.

Prevent the phy driver from registering if the features field is missing.
