Replace IEARLY=1 and IEARLY=2 with IBRANCH_COMMON, which controls if
the entry code branches to a common handler; and IREALMODE_COMMON,
which controls whether the common handler should remain in real mode.
These special cases no longer avoid loading the SRR registers, there
is no point as most of them load the registers immediately anyway.

This allows more code to be moved out of unrelocated regions. The
system call KVMTEST is changed to be open-coded and remain in the
tramp area to avoid having to move it to entry_64.S. The custom nature
of the system call entry code means the hcall case can be made more
streamlined than regular interrupt handlers.
mpe: Incorporate fix from Nick:
Moving KVM test to the common entry code missed the case of HMI and
MCE, which do not do __GEN_COMMON_ENTRY (because they don't want to
switch to virt mode).
This means a MCE or HMI exception that is taken while KVM is running a
guest context will not be switched out of that context, and KVM won't
be notified. Found by running sigfuz in guest with patched host on
POWER9 DD2.3, which causes some TM related HMI interrupts (which are
expected and supposed to be handled by KVM).
This fix adds a __GEN_REALMODE_COMMON_ENTRY for those handlers to add
the KVM test. This makes them look a little more like other handlers
that all use __GEN_COMMON_ENTRY.

As well as moving code out of the unrelocated vectors, this allows the
masked handlers to be moved to common code, and allows the soft_nmi
handler to be generated more like a regular handler.

The real mode interrupt entry points currently use rfid to branch to
the common handler in virtual mode. This is a significant amount of
code, and forces other code (notably the KVM test) to live in the
real mode handler.
In the interest of minimising the amount of code that runs unrelocated
move the switch to virt mode into the common code, and do it with
mtmsrd, which avoids clobbering SRRs (although the post-KVMTEST
performance of real-mode interrupt handlers is not a big concern these
days).
This requires CTR to always be saved (real-mode needs to reach 0xc...)
but that's not a huge impact these days. It could be optimized away in
future.
mpe: Incorporate fix from Nick:
It's possible for interrupts to be replayed when TM is enabled and
suspended, for example rt_sigreturn, where the mtmsrd MSR_KERNEL in
the real-mode entry point to the common handler causes a TM Bad Thing
exception (due to attempting to clear suspended).
The fix for this is to have replay interrupts go to the _virt entry
point and skip the mtmsrd, which matches what happens before this
patch.

Aside from label names and BUG line numbers, the generated code change
is an additional HMI KVM handler added for the "late" KVM handler,
because early and late HMI generation is achieved by defining two
different interrupt types.

These don't provide a large amount of code sharing. Removing them
makes code easier to shuffle around. For example, some of the common

The code generation macro arguments are difficult to read, and
defaults can't easily be used.
This introduces a block where parameters can be set for interrupt
handler code generation by the subsequent macros, and adds the first
generation macro for interrupt entry.
One interrupt handler is converted to the new macros to demonstrate
the change, the rest will be coverted all at once.
No generated code change.

In restore_tm_sigcontexts() we take the trap value directly from the
user sigcontext with no checking:
err |= __get_user(regs->trap, &sc->gp_regs[PT_TRAP]);
This means we can be in the kernel with an arbitrary regs->trap value.
Although that's not immediately problematic, there is a risk we could
trigger one of the uses of CHECK_FULL_REGS():
#define CHECK_FULL_REGS(regs) BUG_ON(regs->trap & 1)
It can also cause us to unnecessarily save non-volatile GPRs again in
save_nvgprs(), which shouldn't be problematic but is still wrong.
It's also possible it could trick the syscall restart machinery, which
relies on regs->trap not being == 0xc00 (see 9a81c16b5275 ("powerpc:
fix double syscall restarts")), though I haven't been able to make
that happen.
Finally it doesn't match the behaviour of the non-TM case, in
restore_sigcontext() which zeroes regs->trap.
So change restore_tm_sigcontexts() to zero regs->trap.
This was discovered while testing Nick's upcoming rewrite of the
syscall entry path. In that series the call to save_nvgprs() prior to
signal handling (do_notify_resume()) is removed, which leaves the
low-bit of regs->trap uncleared which can then trigger the FULL_REGS()
WARNs in setup_tm_sigcontexts().

Pull SELinux updates from Paul Moore:
"We've got twenty SELinux patches for the v5.7 merge window, the
highlights are below:
- Deprecate setting /sys/fs/selinux/checkreqprot to 1.
This flag was originally created to deal with legacy userspace and
the READ_IMPLIES_EXEC personality flag. We changed the default from
1 to 0 back in Linux v4.4 and now we are taking the next step of
deprecating it, at some point in the future we will take the final
step of rejecting 1.
- Allow kernfs symlinks to inherit the SELinux label of the parent
directory. In order to preserve backwards compatibility this is
protected by the genfs_seclabel_symlinks SELinux policy capability.
- Optimize how we store filename transitions in the kernel, resulting
in some significant improvements to policy load times.
- Do a better job calculating our internal hash table sizes which
resulted in additional policy load improvements and likely general
SELinux performance improvements as well.
- Remove the unused initial SIDs (labels) and improve how we handle
initial SIDs.
- Enable per-file labeling for the bpf filesystem.
- Ensure that we properly label NFS v4.2 filesystems to avoid a
temporary unlabeled condition.
- Add some missing XFS quota command types to the SELinux quota
access controls.
- Fix a problem where we were not updating the seq_file position
index correctly in selinuxfs.
- We consolidate some duplicated code into helper functions.
- A number of list to array conversions.
- Update Stephen Smalley's email address in MAINTAINERS"

'minItems' and 'maxItems' apply at the same level as 'items' schemas as
the keywords apply to arrays. What's currently defined is a 3
dimensional matrix with the outer size being undefined. To fix this,
minItems/maxItems needs to be moved up a level.
With this fixed, the example fails validation. For matrix types, the dts
syntax must use brackets (<>) matching the schema definition. In this
case, the inner array size is 2 elements, so let's add the correct
bracketing.

"We've got two audit patches for the v5.7 merge window with a stellar
14 lines changed between the two patches. The patch descriptions are
far more lengthy than the patches themselves, which is a very good
thing for patches this size IMHO. The patches pass our test suites and
a quick summary is below:
- Stop logging inode information when updating an audit file watch.
Since we are not changing the inode, or the fact that we are
watching the associated file, the inode information is just noise
that we can do without.
- Fix a problem where mandatory audit records were missing their
accompanying audit records (e.g. SYSCALL records were missing).
The missing records often meant that we didn't have the necessary

unittest_gpio_remove(), which should not have been called because
the related gpio overlay was not tracked. Another overlay that
was tracked had previously used the same id as the gpio overlay
but had not been untracked when the overlay was removed. Thus the

attempted to remove the reused overlay id.

- Create tracking related helper functions
- Change BUG() to WARN_ON() for overlay id related issues
- Add some additional error checking for valid overlay id values
- Add the missing overlay untrack
- update comment on expectation that overlay ids are assigned in

"We've got a lot of patches (39) for this merge window. Most of these

1. A node fails while writing to the file system.
2. Other nodes use the metadata that was once used by the failed
node.
3. When the node returns to the cluster, its journal is replayed, but
the older metadata blocks overwrite the changes from step 2.

- Fixed the recovery sequence to prevent corruption during journal
replay.

- New improved file system withdraw sequence.
- Fixed how resource group buffers are managed.

"A number of core changes that make things work better in general, code
is simpler and cleaner.
Core changes:
- per-inode file extent tree, for in memory tracking of contiguous
extent ranges to make sure i_size adjustments are accurate
- tree root structures are protected by reference counts, replacing
SRCU that did not cover some cases
- leak detector for tree root structures
- per-transaction pinned extent tracking
- buffer heads are replaced by bios for super block access
- speedup of extent back reference resolution, on an example test
scenario the runtime of send went down from a hour to minutes
- factor out locking scheme used for subvolume writer and NOCOW
exclusion, abstracted as DREW lock, double reader-writer exclusion
(allow either readers or writers)
- cleanup and abstract extent allocation policies, preparation for
zoned device support
- make reflink/clone_range work on inline extents
- add more cancellation point for relocation, improves long response
from 'balance cancel'
- add page migration callback for data pages
- switch to guid for uuids, with additional cleanups of the interface
- make ranged full fsyncs more efficient
- removal of obsolete ioctl flag BTRFS_SUBVOL_CREATE_ASYNC
- remove b-tree readahead from delayed refs paths, avoiding seek and
read unnecessary blocks
Features:
- v2 of ioctl to delete subvolumes, allowing to delete by id and more
future extensions
Fixes:
- fix qgroup rescan worker that could block umount
- fix crash during unmount due to race with delayed inode workers
- fix dellaloc flushing logic that could create unnecessary chunks
