Pull fscrypt updates from Eric Biggers:
"This release, we rework the implementation of creating new encrypted
files in order to fix some deadlocks and prepare for adding fscrypt
support to CephFS, which Jeff Layton is working on.
We also export a symbol in preparation for the above-mentioned CephFS
support and also for ext4/f2fs encrypt+casefold support.
Finally, there are a few other small cleanups.
As usual, all these patches have been in linux-next with no reported
issues, and I've tested them with xfstests"

Some hardware designs have USB typec connector attached to both
SoC and super speed mux. We need to use separate connector node for
such design.

Currently the BUILD_BUG() macro is expanded to the following:
do {
extern void __compiletime_assert_0(void)
__attribute__((error("BUILD_BUG failed")));
if (!(!(1)))
__compiletime_assert_0();
} while (0);
If used in a function body this would obviously produce build errors
with -Wnested-externs and -Werror.
To enable BUILD_BUG() usage in tools/arch/x86/lib/insn.c which perf
includes in intel-pt-decoder, build perf without -Wnested-externs.

Clang-11 shipped support for outputs to asm goto statments along the
fallthrough path. Double up some of the get_user() and related macros
to be able to take advantage of this extended GNU C extension. This
should help improve the generated code's performance for these accesses.

Instead of inlining the stac/mov/clac sequence (which also requires
individual exception table entries and several asm instruction
alternatives entries), just generate "call __put_user_nocheck_X" for the
__put_user() cases, the same way we changed __get_user earlier.
Unlike the get_user() case, we didn't have the same nice infrastructure
to just generate the call with a single case, so this actually has to
change some of the infrastructure in order to do this. But that only
cleans up the code further.
So now, instead of using a case statement for the sizes, we just do the
same thing we've done on the get_user() side for a long time: use the
size as an immediate constant to the asm, and generate the asm that way
directly.
In order to handle the special case of 64-bit data on a 32-bit kernel, I
needed to change the calling convention slightly: the data is passed in
%eax[:%edx], the pointer in %ecx, and the return value is also returned
in %ecx. It used to be returned in %eax, but because of how %eax can
now be a double register input, we don't want mix that with a
single-register output.
The actual low-level asm is easier to handle: we'll just share the code
between the checking and non-checking case, with the non-checking case
jumping into the middle of the function. That may sound a bit too
special, but this code is all very very special anyway, so...

Instead of inlining the whole stac/lfence/mov/clac sequence (which also
requires individual exception table entries and several asm instruction
alternatives entries), just generate "call __get_user_nocheck_X" for the
__get_user() cases.
We can use all the same infrastructure that we already do for the
regular "get_user()", and the end result is simpler source code, and
much simpler code generation.
It also means that when I introduce asm goto with input for
"unsafe_get_user()", there are no nasty interactions with the
__get_user() code.

Buried into NFS, that is.
Generally I'm less enthusiastic about "let's use in_compat_syscall()

in this case it's warranted - that had been an NFS-specific wart,
hopefully not to be repeated in any other filesystems (read: any new
filesystem introducing non-text mount options will get NAKed even if
it doesn't mess the layout up).

Since the destination variable of the check_*_overflow() helpers will
contain a wrapped value on failure, it would be best to make sure callers
really did check the return result of the helper. Adjust the macros to use
a bool-wrapping static inline that is marked with __must_check. This means
the macros can continue to have their type-agnostic behavior while gaining
the function attribute (that cannot be applied directly to macros).

Pull static call support from Ingo Molnar:
"This introduces static_call(), which is the idea of static_branch()
applied to indirect function calls. Remove a data load (indirection)
by modifying the text.
They give the flexibility of function pointers, but with better
performance. (This is especially important for cases where retpolines
would otherwise be used, as retpolines can be pretty slow.)
API overview:
DECLARE_STATIC_CALL(name, func);
DEFINE_STATIC_CALL(name, func);
DEFINE_STATIC_CALL_NULL(name, typename);
static_call(name)(args...);
static_call_cond(name)(args...);
static_call_update(name, func);
x86 is supported via text patching, otherwise basic indirect calls are
used, with function pointers.
There's a second variant using inline code patching, inspired by
jump-labels, implemented on x86 as well.
The new APIs are utilized in the x86 perf code, a heavy user of
function pointers, where static calls speed up the PMU handler by
4.2% (!).
The generic implementation is not really excercised on other
architectures, outside of the trivial test_static_call_init()
self-test"

Pull orphan section checking from Ingo Molnar:
"Orphan link sections were a long-standing source of obscure bugs,
because the heuristics that various linkers & compilers use to handle
them (include these bits into the output image vs discarding them
silently) are both highly idiosyncratic and also version dependent.
Instead of this historically problematic mess, this tree by Kees Cook
(et al) adds build time asserts and build time warnings if there's any
orphan section in the kernel or if a section is not sized as expected.
And because we relied on so many silent assumptions in this area, fix
a metric ton of dependencies and some outright bugs related to this,
before we can finally enable the checks on the x86, ARM and ARM64
platforms"

Pull locking updates from Ingo Molnar:
"These are the locking updates for v5.10:
- Add deadlock detection for recursive read-locks.
The rationale is outlined in commit 224ec489d3cd ("lockdep/
Documention: Recursive read lock detection reasoning")
The main deadlock pattern we want to detect is:
TASK A: TASK B:
read_lock(X);
write_lock(X);
read_lock_2(X);
- Add "latch sequence counters" (seqcount_latch_t):
A sequence counter variant where the counter even/odd value is used
to switch between two copies of protected data. This allows the
read path, typically NMIs, to safely interrupt the write side
critical section.
We utilize this new variant for sched-clock, and to make x86 TSC
handling safer.
