Presumably, all CPUs doing TLB flushes read 'is_lazy'. Because of this,
when we write to it we have to do the cache

The normal flow through the widget sysfs codepath is that
snd_hdac_refresh_widgets() is called once without the sysfs bool set
to set up codec->num_nodes and friends, then another time with the
bool set to actually allocate all the sysfs widgets. However, during
the first time allocation,

For compatibility reason, MAY_CHROOT is always set with MAY_CHDIR.
However, this new flag enable to differentiate a chdir form a chroot.
This is needed for the Landlock LSM to be able to evaluate a new root
directory.

A landlocked process has less privileges than a non-landlocked process
and must then be subject to additional restrictions when manipulating
processes. To be allowed to use ptrace(2) and related syscalls on a
target process, a landlocked process must have a subset of the target
process' rules.
The goal of the program subtype is to be able to have different static
fine-grained verifications for a unique program type.
The struct bpf_verifier_ops gets a new optional function:
is_valid_subtype(). This new verifier is called at the beginning of the

The map can be updated from user space with file descriptor pointing to

Software event output is only enabled by a few prog types right now (TC,
LWT out, XDP, sockops). Many other skb based prog types need
bpf_skb_event_output to produce software event.
Added socket_filter, cg_skb, sk_skb prog types to generate sw event.
Test bpf code is generated from code snippet:
Software event output is only enabled by a few prog types.
This test is to ensure that all supported types are enabled for

This add two Landlock hooks: FS_WALK and FS_PICK.
The FS_WALK hook is used to walk through a file path. A program tied to
this hook will be evaluated for each directory traversal except the last
one if it is the leaf of the path. It is important to differentiate
this hook from FS_PICK to enable

Hi Greg, et al,
Userspace can mmap PCI device memory via the resourceN files in sysfs,
which use pci_mmap_resource(). I think this path is unaware of power
management, so the device may be runtime-suspended, e.g., it may be in
D1, D2, or D3, where it will not respond to memory accesses.

This patch set adds support for TPM devices that implement the I2C
interface defined by TCG PTP specification.
The driver was tested on Raspberry-Pie 3, using Nuvoton NPCT75X TPM.

Hi Tony,
The following series includes minor cleanup patches against the ti-sysc
code. Patches are based on top of all your 5.3 staged branches. Feel free
to pick them up for either 5.3 (if it is not too late) or 5.4 merge window.
The first 4 patches are non-coding changes, and the last patch
The clocks are not yet parsed and prepared until after a successful
sysc_get_clocks(), so there is no need to unprepare the clocks upon
any failure of any of the prior functions in sysc_probe(). The current
code path would have been a no-op because of the clock validity checks
within
Drop the CONFIG_64BIT checks from core regmap code, as it is well
possible to access e.g. an SPI device with 64bit registers from a
32bit CPU. The CONFIG_64BIT checks are still left in place in the
regmap mmio code however.

Add the ti-sysc source files under the OMAP2+ entry so that
