The Intel uncore driver can do a lot of PCI config accesses to read
performance counters. I had a situation on a 4S system where it
was spending 40+% of CPU time grabbing the pci_cfg_lock due to that.
For 64bit x86 with MMCONFIG there isn't really any reason to take
a lock. The

On 4S systems with many uncore events being sampled at a high frequency

This adds the memory domain (on non-LPAE) to the PMD and PTE dumps. This
isn't in the regular PMD bit struct because I couldn't find a clean way to

Early trace callgraphs can be extremely large on systems with
several seconds of boot time. The max_depth parameter limits how
deep the graph trace goes and reduces the output size. This
parameter is the same as the max_graph_depth file in debugfs.

This patch introduces a couple of special IOCTLs which are provided to:
* Inform userspace of firmware partition locations
* Pass event counts and allow userspace to wait on events
* Translate between PFF numbers used by the switch to
port numbers.

This adds standard documentation for the sysfs switchtec attributes and
a RST formatted text file which documents the char device interface.
Jonathan Corbet has indicated he will move this to a new user-space
developer documentation book once it's created.

Hi,
This series fixes some passive mode behavior related to limits and the

It depends on https://patchwork.kernel.org/patch/9594447/ (which is in
