Restore gcc check in mips asm/unroll.h
While raising the gcc version requirement to 4.9, the compile-time check
in the unroll macro was accidentally changed from being used on gcc and
clang to being used on clang only.
Restore the gcc check, changing it from "gcc >= 4.7" to "all gcc".
[ We should probably remove this all entirely: if we remove the check
for CLANG, then the check for GCC can go away. Older versions of clang
are not really appropriate or supported for kernel builds - Linus ]

kbuild: Move -Wtype-limits to W=2
-Wtype-limits is included in -Wextra which is added at W=1. It warns (among other things) that 'comparison of an unsigned variable `< 0` is always false. This causes noisy warnings, especially when used in macros, hence it is more suitable for W=2.

bpf: Check correct cred for CAP_SYSLOG in bpf_dump_raw_ok()
When evaluating access control over kallsyms visibility, credentials at
open() time need to be used, not the "current" creds (though in BPF's
case, this has likely always been the same). Plumb access to associated
file->f_cred down through bpf_dump_raw_ok() and its callers now that
kallsysm_show_value() has been refactored to take struct cred.

kallsyms: Refactor kallsyms_show_value() to take cred
In order to perform future tests against the cred saved during open(), switch kallsyms_show_value() to operate on a cred, and have all current callers pass current_cred(). This makes it very obvious where callers are checking the wrong credential in their "read" contexts. These will be fixed in the coming patches.

Raise gcc version requirement to 4.9
I realize that we fairly recently raised it to 4.8, but the fact is, 4.9
is a much better minimum version to target.
We have a number of workarounds for actual bugs in pre-4.9 gcc versions
(including things like internal compiler errors on ARM), but we also
have some syntactic workarounds for lacking features.
In particular, raising the minimum to 4.9 means that we can now just
assume _Generic() exists, which is likely the much better replacement
for a lot of very convoluted built-time magic with conditionals on
sizeof and/or __builtin_choose_expr() with same_type() etc.
Using _Generic also means that you will need to have a very recent
version of 'sparse', but thats easy to build yourself, and much less of
a hassle than some old gcc version can be.
The latest (in a long string) of reasons for minimum compiler version
upgrades was commit

dm zoned: Fix zone reclaim trigger
Only triggering reclaim based on the percentage of unmapped cache zones can fail to detect cases where reclaim is needed, e.g. if the target has only 2 or 3 cache zones and only one unmapped cache zone, the percentage of free cache zones is higher than DMZ_RECLAIM_LOW_UNMAP_ZONES (30%) and reclaim does not trigger. This problem, combined with the fact that dmz_schedule_reclaim() is called from dmz_handle_bio() without the map lock held, leads to a race between zone allocation and dmz_should_reclaim() result. Depending on the workload applied, this race can lead to the write path waiting forever for a free zone without reclaim being triggered. Fix this by moving dmz_schedule_reclaim() inside dmz_alloc_zone() under the map lock. This results in checking the need for zone reclaim whenever a new data or buffer zone needs to be allocated. Also fix dmz_reclaim_percentage() to always return 0 if the number of unmapped cache (or random) zones is less than or equal to 1.

dm: use bio_uninit instead of bio_disassociate_blkg
bio_uninit is the proper API to clean up a BIO that has been allocated on stack or inside a structure that doesn't come from the BIO allocator. Switch dm to use that instead of bio_disassociate_blkg, which really is an implementation detail. Note that the bio_uninit calls are also moved to the two callers of __send_empty_flush, so that they better pair with the bio_init calls used to initialize them.

- Fixes for Intel PT python based GUI.
- Avoid duplicated sideband events with Intel PT in system wide tracing.
- Remove needless 'dummy' event from TUI menu, used when synthesizing
meta data events for pre-existing processes.
- Fix corner case segfault when pressing enter in a screen without
entries in the TUI for report/top.
- Fixes for time stamp handling in libtraceevent.
- Explicitly set utf-8 encoding in perf flamegraph.
- Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy',
silencing perf build warning.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Some of the most recent, experimental distros are failing, fixes will be
provided, but those gcc/clang versions are not yet in general use and some
are related to linking with libllvm, not the default build.

dm: do not use waitqueue for request-based DM
Given request-based DM now uses blk-mq's blk_mq_queue_inflight() to
determine if outstanding IO has completed (and DM has no control over
the blk-mq state machine used to track outstanding IO) it is unsafe to
wakeup waiter (dm_wait_for_completion) before blk-mq has cleared a
request's state bits (e.g. MQ_RQ_IN_FLIGHT or MQ_RQ_COMPLETE). As
such dm_wait_for_completion() could be left to wait indefinitely if no
other requests complete.
Fix this by eliminating request-based DM's use of waitqueue to wait
for blk-mq requests to complete in dm_wait_for_completion.

ALSA: hda/realtek - Fix Lenovo Thinkpad X1 Carbon 7th quirk subdevice id
1) In snd_hda_pick_fixup(), quirks are first matched by PCI SSID and then, if there is no match, by codec SSID. The Lenovo "ThinkPad X1 Carbon 7th" has an audio chip with PCI SSID 0x2292 and codec SSID 0x2293[1]. Therefore, fix the quirk meant for that device to match on .subdevice == 0x2292. 2) The "Thinkpad X1 Yoga 7th" does not exist. The companion product to the Carbon 7th is the Yoga 4th. That device has an audio chip with PCI SSID 0x2292 and codec SSID 0x2292[2]. Given the behavior of snd_hda_pick_fixup(), it is not possible to have a separate quirk for the Yoga based on SSID. Therefore, merge the quirks meant for the Carbon and Yoga. This preserves the current behavior for the Yoga.

ALSA: hda/hdmi: fix failures at PCM open on Intel ICL and later
When HDMI PCM devices are opened in a specific order, with at least one HDMI/DP receiver connected, ALSA PCM open fails to -EBUSY on the connected monitor, on recent Intel platforms (ICL/JSL and newer). While this is not a typical sequence, at least Pulseaudio does this every time when it is started, to discover the available PCMs. The rootcause is an invalid assumption in hdmi_add_pin(), where the total number of converters is assumed to be known at the time the function is called. On older Intel platforms this held true, but after ICL/JSL, the order how pins and converters are in the subnode list as returned by snd_hda_get_sub_nodes(), was changed. As a result, information for some converters was not stored to per_pin->mux_nids. And this means some pins cannot be connected to all converters, and application instead gets -EBUSY instead at open. The assumption that converters are always before pins in the subnode list, is not really a valid one. Fix the problem in hdmi_parse_codec() by introducing separate loops for discovering converters and pins.

2) Typing '/xxxxx' to filter the symbol to get nothing matched.
3) Pressing enter with no entry selected.
Then it will report a segmentation fault.
It is caused by the lack of check of browser->he_selection when
accessing it's member res_samples in perf_evsel__hists_browse().
These processes are meaningful for specified samples, so we can skip

x86/ldt: use "pr_info_once()" instead of open-coding it badly
Using a mutex for "print this warning only once" is so overdesigned as to be actively offensive to my sensitive stomach. Just use "pr_info_once()" that already does this, although in a (harmlessly) racy manner that can in theory cause the message to be printed twice if more than one CPU races on that "is this the first time" test. [ If somebody really cares about that harmless data race (which sounds very unlikely indeed), that person can trivially fix printk_once() by using a simple atomic access, preferably with an optimistic non-atomic test first before even bothering to treat the pointless "make sure it is _really_ just once" case. A mutex is most definitely never the right primitive to use for something like this. ] Yes, this is a small and meaningless detail in a code path that hardly matters. But let's keep some code quality standards here, and not accept outrageously bad code.

- Fix the XEN PV fallout of the entry code rework
- Fix the 32bit fallout of the entry code rework

Pull x86 fixes from Thomas Gleixner:
"A series of fixes for x86:
- Reset MXCSR in kernel_fpu_begin() to prevent using a stale user
space value.
- Prevent writing MSR_TEST_CTRL on CPUs which are not explicitly
whitelisted for split lock detection. Some CPUs which do not
support it crash even when the MSR is written to 0 which is the
default value.
- Fix the XEN PV fallout of the entry code rework
- Fix the 32bit fallout of the entry code rework
- Add more selftests to ensure that these entry problems don't come
back.
- Disable 16 bit segments on XEN PV. It's not supported because XEN
PV does not implement ESPFIX64"

A set of interrupt chip driver fixes:
- Ensure the atomicity of affinity updates in the GIC driver.
- Don't try to sleep in atomic context when waiting for the GICv4.1 to
respond. Use polling instead.
- Typo fixes in Kconfig and warnings.
