Pull for IPMI driver for 4.14
Mostly a restructure of the kcs_bmc driver to make it easier to
use with different types of devices, and just to clean things up and
improve things.
Also some bug fixes for the kcs_bmc driver.
One fix to the IPMI watchdog to stop the timer when the action is none.
Not a big deal, but it's the right thing to do.

Merge tag 'fs.openat2.unknown_flags.v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull openat2 fixes from Christian Brauner:
- Remove the unused VALID_UPGRADE_FLAGS define we carried from an
extension to openat2() that we haven't merged. Aleksa might be
getting back to it at some point but just not right now.
- openat2() used to accidently ignore unknown flag values in the upper
32 bits.
The new openat2() syscall verifies that no unknown O-flag values are
set and returns an error to userspace if they are while the older
open syscalls like open() and openat() simply ignore unknown flag
values:
#define O_FLAG_CURRENTLY_INVALID (1 << 31)
struct open_how how = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID,
.resolve = 0,
};
/* fails */
fd = openat2(-EBADF, "/dev/null", &how, sizeof(how));
/* succeeds */
fd = openat(-EBADF, "/dev/null", O_RDONLY | O_FLAG_CURRENTLY_INVALID);
However, openat2() silently truncates the upper 32 bits meaning:
#define O_FLAG_CURRENTLY_INVALID_LOWER32 (1 << 31)
#define O_FLAG_CURRENTLY_INVALID_UPPER32 (1 << 40)
struct open_how how_lowe32 = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_LOWER32,
};
struct open_how how_upper32 = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_UPPER32,
};
/* fails */
fd = openat2(-EBADF, "/dev/null", &how_lower32, sizeof(how_lower32));
/* succeeds */
fd = openat2(-EBADF, "/dev/null", &how_upper32, sizeof(how_upper32));
Fix this by preventing the immediate truncation in build_open_flags()
and add a compile-time check to catch when we add flags in the upper
32 bit range.

Pull timer updates from Thomas Gleixner:
"Time and clocksource/clockevent related updates:
Core changes:
- Infrastructure to support per CPU "broadcast" devices for per CPU
clockevent devices which stop in deep idle states. This allows us
to utilize the more efficient architected timer on certain ARM SoCs
for normal operation instead of permanentely using the slow to
access SoC specific clockevent device.
- Print the name of the broadcast/wakeup device in /proc/timer_list
- Make the clocksource watchdog more robust against delays between
reading the current active clocksource and the watchdog
clocksource. Such delays can be caused by NMIs, SMIs and vCPU
preemption.
Handle this by reading the watchdog clocksource twice, i.e. before
and after reading the current active clocksource. In case that the
two watchdog reads shows an excessive time delta, the read sequence
is repeated up to 3 times.
- Improve the debug output and add a test module for the watchdog
mechanism.
- Reimplementation of the venerable time64_to_tm() function with a
faster and significantly smaller version. Straight from the source,
i.e. the author of the related research paper contributed this!
Driver changes:
- No new drivers, not even new device tree bindings!
- Fixes, improvements and cleanups and all over the place"

Updates for the interrupt subsystem:
Core changes:
- Cleanup and simplification of common code to invoke the low level
interrupt flow handlers when this invocation requires irqdomain
resolution. Add the necessary core infrastructure.
- Provide a proper interface for modular PMU drivers to set the
interrupt affinity.
- Add a request flag which allows to exclude interrupts from spurious
interrupt detection. Useful especially for IPI handlers which always
return IRQ_HANDLED which turns the spurious interrupt detection into a
pointless waste of CPU cycles.
Driver changes:
- Bulk convert interrupt chip drivers to the new irqdomain low level flow
handler invocation mechanism.
- Add device tree bindings for the Renesas R-Car M3-W+ SoC
- Enable modular build of the Qualcomm PDC driver
- The usual small fixes and improvements.

A fix for the CPU hotplug and cpusets interaction:
cpusets delegate the hotplug work to a workqueue to prevent a lock order inversion vs. the CPU hotplug lock. The work is not flushed before the hotplug operation returns which creates user visible inconsistent state.

mm,hwpoison: make get_hwpoison_page() call get_any_page()
__get_hwpoison_page() could fail to grab refcount by some race condition, so it's helpful if we can handle it by retrying. We already have retry logic, so make get_hwpoison_page() call get_any_page() when called from memory_failure(). As a result, get_hwpoison_page() can return negative values (i.e. error code), so some callers are also changed to handle error cases. soft_offline_page() does nothing for -EBUSY because that's enough and users in userspace can easily handle it. unpoison_memory() is also unchanged because it's broken and need thorough fixes (will be done later).

mm,hwpoison: send SIGBUS with error virutal address
Now an action required MCE in already hwpoisoned address surely sends a SIGBUS to current process, but the SIGBUS doesn't convey error virtual address. That's not optimal for hwpoison-aware applications. To fix the issue, make memory_failure() call kill_accessing_process(), that does pagetable walk to find the error virtual address. It could find multiple virtual addresses for the same error page, and it seems hard to tell which virtual address is correct one. But that's rare and sending incorrect virtual address could be better than no address. So let's report the first found virtual address for now.

mm/page_alloc: split pcp->high across all online CPUs for cpuless nodes
Dave Hansen reported the following about Feng Tang's tests on a machine
with persistent memory onlined as a DRAM-like device.
Feng Tang tossed these on a "Cascade Lake" system with 96 threads and
~512G of persistent memory and 128G of DRAM. The PMEM is in "volatile
use" mode and being managed via the buddy just like the normal RAM.
The PMEM zones are big ones:
present 65011712 = 248 G
high 134595 = 525 M
The PMEM nodes, of course, don't have any CPUs in them.
With your series, the pcp->high value per-cpu is 69584 pages or about
270MB per CPU. Scaled up by the 96 CPU threads, that's ~26GB of
worst-case memory in the pcps per zone, or roughly 10% of the size of
the zone.
This should not cause a problem as such although it could trigger reclaim
due to pages being stored on per-cpu lists for CPUs remote to a node. It
is not possible to treat cpuless nodes exactly the same as normal nodes
but the worst-case scenario can be mitigated by splitting pcp->high across
all online CPUs for cpuless memory nodes.

mm/page_alloc: allow high-order pages to be stored on the per-cpu lists
The per-cpu page allocator (PCP) only stores order-0 pages. This means
that all THP and "cheap" high-order allocations including SLUB contends on
the zone->lock. This patch extends the PCP allocator to store THP and
"cheap" high-order pages. Note that struct per_cpu_pages increases in
size to 256 bytes (4 cache lines) on x86-64.
Note that this is not necessarily a universal performance win because of
how it is implemented. High-order pages can cause pcp->high to be
exceeded prematurely for lower-orders so for example, a large number of
THP pages being freed could release order-0 pages from the PCP lists.
Hence, much depends on the allocation/free pattern as observed by a single
CPU to determine if caching helps or hurts a particular workload.
That said, basic performance testing passed. The following is a netperf
UDP_STREAM test which hits the relevant patches as some of the network
allocations are high-order.

Functionally, a patch like this is necessary to make bulk allocation of
high-order pages work with similar performance to order-0 bulk
allocations. The bulk allocator is not updated in this series as it would
have to be determined by bulk allocation users how they want to track the
order of pages allocated with the bulk allocator.

alpha: remove DISCONTIGMEM and NUMA
Patch series "Remove DISCONTIGMEM memory model", v3. SPARSEMEM memory model was supposed to entirely replace DISCONTIGMEM a (long) while ago. The last architectures that used DISCONTIGMEM were updated to use other memory models in v5.11 and it is about the time to entirely remove DISCONTIGMEM from the kernel. This set removes DISCONTIGMEM from alpha, arc and m68k, simplifies memory model selection in mm/Kconfig and replaces usage of redundant CONFIG_NEED_MULTIPLE_NODES and CONFIG_FLAT_NODE_MEM_MAP with CONFIG_NUMA and CONFIG_FLATMEM respectively. I've also removed NUMA support on alpha that was BROKEN for more than 15 years. There were also minor updates all over arch/ to remove mentions of DISCONTIGMEM in comments and #ifdefs. This patch (of 9): NUMA is marked broken on alpha for more than 15 years and DISCONTIGMEM was replaced with SPARSEMEM in v5.11. Remove both NUMA and DISCONTIGMEM support from alpha.

mm/page_alloc: move free_the_page
Patch series "Allow high order pages to be stored on PCP", v2. The per-cpu page allocator (PCP) only handles order-0 pages. With the series "Use local_lock for pcp protection and reduce stat overhead" and "Calculate pcp->high based on zone sizes and active CPUs", it's now feasible to store high-order pages on PCP lists. This small series allows PCP to store "cheap" orders where cheap is determined by PAGE_ALLOC_COSTLY_ORDER and THP-sized allocations. This patch (of 2): In the next page, free_compount_page is going to use the common helper free_the_page. This patch moves the definition to ease review. No functional change.
