Commit a5cbe05a66 ("bpf: Implement bpf iterator for
map elements") added bpf iterator support for
map elements. The map element bpf iterator requires
info to identify a particular map. In the above
commit, the attr->link_create.target_fd is used
to carry map_fd and an enum bpf_iter_link_info
is added to uapi to specify the target_fd actually
representing a map_fd:
enum bpf_iter_link_info {
BPF_ITER_LINK_UNSPEC = 0,
BPF_ITER_LINK_MAP_FD = 1,
MAX_BPF_ITER_LINK_INFO,
};
This is an extensible approach as we can grow
enumerator for pid, cgroup_id, etc. and we can
unionize target_fd for pid, cgroup_id, etc.
But in the future, there are chances that
more complex customization may happen, e.g.,
for tasks, it could be filtered based on
both cgroup_id and user_id.
This patch changed the uapi to have fields
__aligned_u64 iter_info;
__u32 iter_info_len;
for additional iter_info for link_create.
The iter_info is defined as
union bpf_iter_link_info {
struct {
__u32 map_fd;
} map;
};
So future extension for additional customization
will be easier. The bpf_iter_link_info will be
passed to target callback to validate and generic
bpf_iter framework does not need to deal it any
more.
Note that map_fd = 0 will be considered invalid
and -EBADF will be returned to user space.

The three APIs for non-scheduler code to set SCHED_FIFO are:

- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low'
priority level, plus sched_set_normal() to set the policy back to
non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in

Running posix CPU timers in hard interrupt context has a few downsides:
- For PREEMPT_RT it cannot work as the expiry code needs to take
sighand lock, which is a 'sleeping spinlock' in RT. The original RT
approach of offloading the posix CPU timer handling into a high
priority thread was clumsy and provided no real benefit in general.
- For fine grained accounting it's just wrong to run this in context of
the timer interrupt because that way a process specific CPU time is
accounted to the timer interrupt.
- Long running timer interrupts caused by a large amount of expiring
timers which can be created and armed by unpriviledged user space.
There is no hard requirement to expire them in interrupt context.
If the signal is targeted at the task itself then it won't be delivered
before the task returns to user space anyway. If the signal is targeted at
a supervisor process then it might be slightly delayed, but posix CPU
timers are inaccurate anyway due to the fact that they are tied to the
tick.
Provide infrastructure to schedule task work which allows splitting the
posix CPU timer code into a quick check in interrupt context and a thread
context expiry and signal delivery function. This has to be enabled by
architectures as it requires that the architecture specific KVM
implementation handles pending task work before exiting to guest mode.

struct to contain the state, now containing only a single u16 for the
available index. In the future we can add fields to this struct.

The branch itself includes a small number of patches and is also
independently merged by a couple of other trees.
That shouldn't cause any conflicts by itself.

Pull hmm updates from Jason Gunthorpe:
"Ralph has been working on nouveau's use of hmm_range_fault() and
migrate_vma() which resulted in this small series. It adds reporting
of the page table order from hmm_range_fault() and some optimization
of migrate_vma():
- Report the size of the page table mapping out of hmm_range_fault().
This makes it easier to establish a large/huge/etc mapping in the
device's page table.
- Allow devices to ignore the invalidations during migration in cases
where the migration is not going to change pages.
For instance migrating pages to a device does not require the
device to invalidate pages already in the device.
- Update nouveau and hmm_tests to use the above"

"This is the bulk of GPIO changes for the v5.9 kernel cycle.
There is nothing too exciting in it, but a new macro that fixes a
build failure on a minor ARM32 platform that appeared yesterday is
part of it so we better merge it.
Core changes:
- Introduce the for_each_requested_gpio() macro to help in dependent
code all over the place. Also patch a few locations to use it while
we are at it.
- Split out the sysfs code into its own file.
- Split out the character device code into its own file, then make a
set of refactorings and improvements to this code. We are setting
the stage to revamp the userspace API a bit in the next cycle.
- Fix a whole slew of kerneldoc that was wrong or missing.
New drivers:
- The PCA953x driver now supports the PCAL9535.
Driver improvements:
- A host of incremental modernizations and improvements to the
PCA953x driver.
- Incremental improvements to the Xilinx Zynq driver.
- Some improvements to the GPIO aggregator driver.
- I ran all over the place switching all threaded and other drivers
requesting their own IRQ while using the core GPIO IRQ helpers to
pass the GPIO irq chip as a template instead of calling the
explicit set-up functions. Next merge window we may retire the old
code altogether"

Pull driver core updates from Greg KH:
"Here is the "big" set of changes to the driver core, and some drivers
using the changes, for 5.9-rc1.
"Biggest" thing in here is the device link exposure in sysfs, to help
to tame the madness that is SoC device tree representations and driver
interactions with it.
Other stuff in here that is interesting is:
- device probe log helper so that drivers can report problems in a
unified way easier.
- devres functions added
- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
incorrect sysfs file permissions
- documentation cleanups
- ability for debugfs to be present in the kernel, yet not exposed to
userspace. Needed for systems that want it enabled, but do not
trust users, so they can still use some kernel functions that were
otherwise disabled.

Certain watchdogs require the watchdog only to be pinged within a
specific time window, pinging too early or too late cause the watchdog
to fire. In cases where this sort of watchdog has been started before
kernel comes up, we must adjust the watchdog keepalive window to match
the actually running timer, so add a new driver API for this purpose.
