This patch switches compiler-based stack initialization from 0xAA
to zero pattern, resulting in much more efficient code and saner
defaults for uninitialized local variables.

Upstream commit f0fe00d4972a8cd4b98cc2c29758615e4d51cdfe.
In addition to -ftrivial-auto-var-init=pattern (used by
CONFIG_INIT_STACK_ALL now) Clang also supports zero initialization for
locals enabled by -ftrivial-auto-var-init=zero. The future of this flag
is still being debated (see https://bugs.llvm.org/show_bug.cgi?id=45497).
Right now it is guarded by another flag,
-enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang,
which means it may not be supported by future Clang releases. Another
possible resolution is that -ftrivial-auto-var-init=zero will persist
(as certain users have already started depending on it), but the name
of the guard flag will change.
In the meantime, zero initialization has proven itself as a good
production mitigation measure against uninitialized locals. Unlike pattern
initialization, which has a higher chance of triggering existing bugs,
zero initialization provides safe defaults for strings, pointers, indexes,
and sizes. On the other hand, pattern initialization remains safer for
return values. Chrome OS and Android are moving to using zero
initialization for production builds.
Performance-wise, the difference between pattern and zero initialization
is usually negligible, although the generated code for zero
initialization is more compact.
This patch renames CONFIG_INIT_STACK_ALL to CONFIG_INIT_STACK_ALL_PATTERN
and introduces another config option, CONFIG_INIT_STACK_ALL_ZERO, that
enables zero initialization for locals if the corresponding flags are
supported by Clang.

Commit 323ebb61e3 ("net: use listified RX for handling GRO_NORMAL
skbs") made use of listified skb processing for the users of
napi_gro_frags().
The same technique can be used in a way more common napi_gro_receive()
to speed up non-merged (GRO_NORMAL) skbs for a wide range of drivers
including gro_cells and mac80211 users.
This slightly changes the return value in cases where skb is being
dropped by the core stack, but it seems to have no impact on related
drivers' functionality.
gro_normal_batch is left untouched as it's very individual for every
single system configuration and might be tuned in manual order to
achieve an optimal performance.

commit fce2ff728f95b8894db14f51c9274dc56c37616f upstream.
In nl80211_set_station(), we check NL80211_ATTR_HE_6GHZ_CAPABILITY
and then use NL80211_ATTR_HE_CAPABILITY, which is clearly wrong.
Fix this to use NL80211_ATTR_HE_6GHZ_CAPABILITY as well.

commit 11990a5bd7e558e9203c1070fc52fb6f0488e75b upstream.
The only-root-readable /sys/module/$module/sections/$section files
did not truncate their output to the available buffer size. While most
paths into the kernfs read handlers end up using PAGE_SIZE buffers,
it's possible to get there through other paths (e.g. splice, sendfile).
Actually limit the output to the "count" passed into the read function,
and report it back correctly. *sigh*

Certain Type-C USB adapters (which doesn't support PD),
when connected switch the USB port type from USB3 to USB2.
This is because the clients of UCSI receive a notification
when the response for GET_CONNECTOR_STATUS has empty partner type.
Example UCSI IPC log:
213.212929: sync_write: CONTROL: 12 00 01 00 00 00 00 00
213.216613: read: CCI: 02 09 00 80
213.221135: read: MSG_IN: 00 00 0d 00 00 00 00 00 00
Parsing the logs gives the following information:
Connect Status: connected
Power Operation Mode: USB Type-C Current - 3A
Power Direction: consumer
Connector Partner Type: Reserved
Fix this by checking whether partner changed flag is set
and not notify UCSI clients if it is not set.
