Pull vfs mount infrastructure updates from Al Viro:
"The rest of core infrastructure; no new syscalls in that pile, but the
old parts are switched to new infrastructure. At that point
conversions of individual filesystems can happen independently; some
are done here (afs, cgroup, procfs, etc.), there's also a large series
outside of that pile dealing with NFS (quite a bit of option-parsing
stuff is getting used there - it's one of the most convoluted
filesystems in terms of mount-related logics), but NFS bits are the
next cycle fodder.
It got seriously simplified since the last cycle; documentation is
probably the weakest bit at the moment - I considered dropping the
commit introducing Documentation/filesystems/mount_api.txt (cutting
the size increase by quarter ;-), but decided that it would be better
to fix it up after -rc1 instead.
That pile allows to do followup work in independent branches, which
should make life much easier for the next cycle. fs/super.c size
increase is unpleasant; there's a followup series that allows to
shrink it considerably, but I decided to leave that until the next
cycle"

As all the memblock allocation functions return NULL in case of error
rather than panic(), the duplicates with _nopanic suffix can be removed.

Add check for the return value of memblock_alloc*() functions and call
panic() in case of error. The panic message repeats the one used by
panicing memblock allocators with adjustment of parameters to include
only relevant ones.
The replacement was mostly automated with semantic patches like the one
below with manual massaging of format strings.
@@
expression ptr, size, align;
@@
ptr = memblock_alloc(size, align);
+ if (!ptr)
+ panic("%s: Failed to allocate %lu bytes align=0x%lx\n", __func__, size, align);

Add panic() calls if memblock_alloc*() returns NULL.
Most of the changes are simply addition of
if(!ptr)
panic();
statements after the calls to memblock_alloc*() variants.
Exceptions are pcpu_populate_pte() and kernel_map_range() that were
slightly refactored to accommodate the change.

limit specified by its max_addr parameter and panics if the allocation
fails. Replace its usage with memblock_phys_alloc_range() and make the
callers check the return value and panic in case of error.

The memblock_phys_alloc_try_nid() function tries to allocate memory from
the requested node and then falls back to allocation from any node in
the system. The memblock_alloc_base() fallback used by this function
panics if the allocation fails.
Replace the memblock_alloc_base() fallback with the direct call to
memblock_alloc_range_nid() and update the memblock_phys_alloc_try_nid()
callers to check the returned value and panic in case of error.

The calls to memblock_alloc_base(size, align, MEMBLOCK_ALLOC_ANYWHERE)
and memblock_phys_alloc(size, align) are equivalent as both try to
allocate 'size' bytes with 'align' alignment anywhere in the memory and
panic if hte allocation fails.
The conversion is done using the following semantic patch:
@@
expression size, align;
@@
- memblock_alloc_base(size, align, MEMBLOCK_ALLOC_ANYWHERE)
+ memblock_phys_alloc(size, align)

Since only the virtual address of allocated blocks is used, lets use
functions returning directly virtual address.
Those functions have the advantage of also zeroing the block.

Patch series "Refine memblock API", v2.
Current memblock API is quite extensive and, which is more annoying,
duplicated. Except the low-level functions that allow searching for a
free memory region and marking it as reserved, memblock provides three
(well, two and a half) sets of functions to allocate memory.
There are several overlapping functions that return a physical address
and there are functions that return virtual address. Those that return
the virtual address may also clear the allocated memory. And, on top of
all that, some allocators panic and some return NULL in case of error.
This set tries to reduce the mess, and trim down the amount of memblock
allocation methods.
Patches 1-10 consolidate the functions that return physical address of
the allocated memory
Patches 11-13 are some trivial cleanups
Patches 14-19 add checks for the return value of memblock_alloc*() and
panics in case of errors. The patches 14-18 include some minor
refactoring to have better readability of the resulting code and patch
19 is a mechanical addition of
if (!ptr)
panic();
after memblock_alloc*() calls.
And, finally, patches 20 and 21 remove panic() calls memblock and
_nopanic variants from memblock.
This patch (of 21):
The allocation of the page tables memory in openrics uses
memblock_phys_alloc() and then converts the returned physical address to
virtual one. Use memblock_alloc_raw() and add a panic() if the
allocation fails.

Pull x86 tsx fixes from Thomas Gleixner:
"This update provides kernel side handling for the TSX erratum of Intel
Skylake (and later) CPUs.
On these CPUs Intel Transactional Synchronization Extensions (TSX)
functions can result in unpredictable system behavior under certain
circumstances.
The issue is mitigated with an microcode update which utilizes
Performance Monitoring Counter (PMC) 3 when TSX functions are in use.
This mitigation is enabled unconditionally by the updated microcode.
As a consequence the usage of TSX functions can cause corrupted
performance monitoring results for events which utilize PMC3. The
corruption is silent on kernels which have no update for this issue.
This update makes the kernel aware of the PMC3 utilization by the
microcode:
The microcode offers a possibility to enforce TSX abort which prevents
the malfunction and frees up PMC3. The enforced TSX abort requires the
TSX using application to have a software fallback path implemented;
abort handlers which solely retry the transaction will fail over and
over.
The enforced TSX abort request is issued by the kernel when:
- enforced TSX abort is enabled (PMU attribute)
- A performance monitoring request needs PMC3
When PMC3 is not longer used by the kernel the TSX force abort request
is cleared.
The enforced TSX abort mechanism is enabled by default and can be
controlled by the administrator via the new PMU attribute
'allow_tsx_force_abort'. This attribute is only visible when updated
microcode is detected on affected systems. Writing '0' disables the
enforced TSX abort mechanism, '1' enables it.
As a result of disabling the enforced TSX abort mechanism, PMC3 is
permanentely unavailable for performance monitoring which can cause
performance monitoring requests to fail or switch to multiplexing
mode"

Pull tracing updates from Steven Rostedt:
"The biggest change for this release is in the histogram code:
- Add "onchange(var)" histogram handler that executes a action when
$var changes.
- Add new "snapshot()" action for histogram handlers, that causes a
snapshot of the ring buffer when triggered. ie.
onchange(var).snapshot() will trigger a snapshot if var changes.
- Add alternative for "trace()" action. Currently, to trigger a
synthetic event, the name of that event is used as the handler
name, which is inconsistent with the other actions.
onchange(var).synthetic(param) where it can now be
onchange(var).trace(synthetic, param). The older method will still
be allowed, as long as the synthetic events do not overlap with
other handler names.
- The histogram documentation at testcases were updated for the new
changes.
Outside of the histogram code, we have:
- Added a quicker way to enable set_ftrace_filter files, that will
make it much quicker to bisect tracing a function that shouldn't be
traced and crashes the kernel. (You can echo in numbers to
set_ftrace_filter, and it will select the corresponding function
that is in available_filter_functions).
- Some better displaying of the tracing data (and more information
was added).
The rest are small fixes and more clean ups to the code"

- add debugfs support for dumping dma-debug information (Corentin
Labbe)
- Kconfig cleanups (Andy Shevchenko and me)
- debugfs cleanups (Greg Kroah-Hartman)
- improve dma_map_resource and use it in the media code
- arch_setup_dma_ops / arch_teardown_dma_ops cleanups
- various small cleanups and improvements for the per-device coherent
allocator
- make the DMA mask an upper bound and don't fail "too large" dma mask
in the remaning two architectures - this will allow big driver
cleanups in the following merge windows
* tag 'dma-mapping-5.1' of git://git.infradead.org/users/hch/dma-mapping: (21 commits)
Documentation/DMA-API-HOWTO: update dma_mask sections
sparc64/pci_sun4v: allow large DMA masks
sparc64/iommu: allow large DMA masks
sparc64: refactor the ali DMA quirk
ccio: allow large DMA masks
dma-mapping: remove the DMA_MEMORY_EXCLUSIVE flag
dma-mapping: remove dma_mark_declared_memory_occupied
dma-mapping: move CONFIG_DMA_CMA to kernel/dma/Kconfig
dma-mapping: improve selection of dma_declare_coherent availability
dma-mapping: remove an incorrect __iommem annotation
of: select OF_RESERVED_MEM automatically
device.h: dma_mem is only needed for HAVE_GENERIC_DMA_COHERENT
mfd/sm501: depend on HAS_DMA
dma-mapping: add a kconfig symbol for arch_teardown_dma_ops availability
dma-mapping: add a kconfig symbol for arch_setup_dma_ops availability
dma-mapping: move debug configuration options to kernel/dma
dma-debug: add dumping facility via debugfs
dma: debug: no need to check return value of debugfs_create functions
videobuf2: replace a layering violation with dma_map_resource
dma-mapping: don't BUG when calling dma_map_resource on RAM

Pull arm64 updates from Catalin Marinas:
- Pseudo NMI support for arm64 using GICv3 interrupt priorities
- uaccess macros clean-up (unsafe user accessors also merged but
reverted, waiting for objtool support on arm64)
- ptrace regsets for Pointer Authentication (ARMv8.3) key management
- inX() ordering w.r.t. delay() on arm64 and riscv (acks in place by
the riscv maintainers)
- arm64/perf updates: PMU bindings converted to json-schema, unused
variable and misleading comment removed
- arm64/debug fixes to ensure checking of the triggering exception
level and to avoid the propagation of the UNKNOWN FAR value into the
si_code for debug signals
- Workaround for Fujitsu A64FX erratum 010001
- lib/raid6 ARM NEON optimisations
- NR_CPUS now defaults to 256 on arm64
- Minor clean-ups (documentation/comments, Kconfig warning, unused
asm-offsets, clang warnings)
- MAINTAINERS update for list information to the ARM64 ACPI entry
