Back in 2008 we extended the capability bits from 32 to 64, and we did
it by extending the single 32-bit capability word from one word to an
array of two words.  It was then obfuscated by hiding the "2" behind two
macro expansions, with the reasoning being that maybe it gets extended
further some day.

That reasoning may have been valid at the time, but the last thing we
want to do is to extend the capability set any more.  And the array of
values not only causes source code oddities (with loops to deal with
it), but also results in worse code generation.  It's a lose-lose
situation.

So just change the 'u32[2]' into a 'u64' and be done with it.

We still have to deal with the fact that the user space interface is
designed around an array of these 32-bit values, but that was the case
before too, since the array layouts were different (ie user space
doesn't use an array of 32-bit values for individual capability masks,
but an array of 32-bit slices of multiple masks).

So that marshalling of data is actually simplified too, even if it does
remain somewhat obscure and odd.

This was all triggered by my reaction to the new "cap_isidentical()"
introduced recently.  By just using a saner data structure, it went from

	unsigned __capi;
	CAP_FOR_EACH_U32(__capi) {
		if (a.cap[__capi] != b.cap[__capi])
			return false;
	}
	return true;

to just being

	return a.val == b.val;

instead.  Which is rather more obvious both to humans and to compilers.

   - Fix a deadlock in the free space allocator due to the AG-walking
     algorithm forgetting to follow AG-order locking rules

   - Make the inode allocator prefer existing free inodes instead of
     failing to allocate new inode chunks when free space is low

   - Set minleft correctly when setting allocator parameters for bmap
     changes

   - Fix uninitialized variable access in the getfsmap code

   - Make a distinction between active and passive per-AG structure
     references. For now, active references are taken to perform some
     work in an AG on behalf of a high level operation; passive
     references are used by lower level code to finish operations
     started by other threads. Eventually this will become part of
     online shrink

   - Split out all the different allocator strategies into separate
     functions to move us away from design antipattern of filling out a
     huge structure for various differentish things and issuing a single
     function multiplexing call

Clang is unable to handle the situation that a chunk of inline
assembly ends with a compat branch instruction and then compiler
generates another control transfer instruction immediately after
this compat branch. The later instruction will end up in forbidden
slot and cause exception.

Workaround by add a option to control the use of compact branch.
Currently it's selected by CC_IS_CLANG and hopefully we can change
it to a version check in future if clang manages to fix it.

Commit 226fae12 ("vc_screen: move load of struct vc_data pointer in
vcs_read() to avoid UAF") moved the call to vcs_vc() into the loop.

While doing this it also moved the unconditional assignment of

	ret = -ENXIO;

This unconditional assignment was valid outside the loop but within it
it clobbers the actual value of ret.

To avoid this only assign "ret = -ENXIO" when actually needed.

[ Also, the 'goto unlock_out" needs to be just a "break", so that it
  does the right thing when it exits on later iterations when partial
  success has happened - Linus ]

access(2) remains commonly used, for example on exec:
access("/etc/ld.so.preload", R_OK)

or when running gcc: strace -c gcc empty.c

  % time     seconds  usecs/call     calls    errors syscall
  ------ ----------- ----------- --------- --------- ----------------
    0.00    0.000000           0        42        26 access

It falls down to do_faccessat without the AT_EACCESS flag, which in turn
results in allocation of new creds in order to modify fsuid/fsgid and
caps.  This is a very expensive process single-threaded and most notably
multi-threaded, with numerous structures getting refed and unrefed on
imminent new cred destruction.

Turns out for typical consumers the resulting creds would be identical
and this can be checked upfront, avoiding the hard work.

An access benchmark plugged into will-it-scale running on Cascade Lake
shows:

    test     proc     before       after
    access1     1    1310582     2908735    (+121%) # distinct files
    access1    24    4716491    63822173   (+1353%) # distinct files
    access2    24    2378041     5370335    (+125%) # same file

The above benchmarks are not integrated into will-it-scale, but can be
found in a pull request:

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've got a huge number of patches that improve code
  readability along with minor bug fixes, while we've mainly fixed some
  critical issues in recently-added per-block age-based extent_cache,
  atomic write support, and some folio cases.

  Enhancements:

   - add sysfs nodes to set last_age_weight and manage
     discard_io_aware_gran

   - show ipu policy in debugfs

   - reduce stack memory cost by using bitfield in struct f2fs_io_info

   - introduce trace_f2fs_replace_atomic_write_block

   - enhance iostat support and adds flush commands

  Bug fixes:

   - revert "f2fs: truncate blocks in batch in __complete_revoke_list()"

   - fix kernel crash on the atomic write abort flow

   - call clear_page_private_reference in .{release,invalid}_folio

   - support .migrate_folio for compressed inode

   - fix cgroup writeback accounting with fs-layer encryption

   - retry to update the inode page given data corruption

   - fix kernel crash due to NULL io->bio

   - fix some bugs in per-block age-based extent_cache:
       - wrong calculation of block age
       - update age extent in f2fs_do_zero_range()
       - update age extent correctly during truncation"

KUnit's 'hooks.o' file need to be built-in whenever KUnit is enabled
(even if CONFIG_KUNIT=m).  We'd previously attemtped to do this by
adding 'kunit/hooks.o' to obj-y in lib/Makefile, but this caused hooks.c
to be rebuilt even when it was unchanged.

Instead, always recurse into lib/kunit using obj-y when KUnit is
enabled, and add the hooks there.

Fixes: 7170b7ed ("kunit: Add "hooks" to call into KUnit when it's built as a module").

Currently, out of every Ralink SoC, only the dt-binding of the MT7621 SoC
uses pinctrl. Because of this, PINCTRL is not selected at all. Make
SOC_MT7621 select PINCTRL.

Remove PINCTRL_MT7621, enabling it for the MT7621 SoC will be handled under

In c0_compare_int_usable we clear compare interrupt by write value
just read out from counter to compare register.

However sometimes if those all instructions are graduated together
then it's possible that at the time compare register is written, the
counter haven't progressed, thus the interrupt is triggered again.

It also applies to QEMU that instructions is executed significantly
faster then counter.

Offset the value used to clear interrupt by one to prevent that happen.

CP0_CMGCRBASE is not always available on CPS enabled system
such as early proAptiv.

For early SMP bring up where we can't safely access memeory,
we patch the entry of CPS NMI vector to inject CMGCR address
directly into register during early core bringup.

For VPE bringup as the core is already coherenct at that point
we just read the variable to obtain the address.
