Introducing usb_for_each_port(). It works the same way as
usb_for_each_dev(), but instead of going through every USB
device in the system, it walks through the USB ports in the

Adding functions that can be used to link/unlink ports -
USB ports, TBT3/USB4 ports, DisplayPorts and so on - to
the USB Type-C connectors they are attached to inside a
system. The symlink that is created for the port device is
named "connector".
Initially only ACPI is supported. ACPI port object
The connectors may be registered after the ports, so the
"connector" links need to be created for the ports also when
ever a new connector gets registered.

Slot resets are bus resets with additional logic to prevent a device
from being removed during the reset. Currently slot and bus resets have
separate implementations in pci.c, complicating higher level logic. As
discussed on the mailing list, they should be combined into a generic
function which pe

When suspending the driver, anx7625_power_standby() will be called to
turn off reset-gpios and enable-gpios. However, power supplies are not
disabled. To save power, the driver can get the power supply regulators
and turn off them in anx7625_power_standby().

Now that the sanitization process will make pages available by calling
sgx_free_epc_page(), sgx_setup_epc_section() should not touch to
sgx_nr_free_pages. This will result sgx_nr_free_pages to contain 2x the
number of actual free pages. Simply, remove the statement.

Add two debugs attributes:
* /sys/kernel/debug/x86/sgx_nr_all_pages
* /sys/kernel/debug/x86/sgx_nr_free_pages
These provide useful statistics for testing purposes.
E.g. on a NUC7CJYH2, when no enclaves are running, and EPC set to 32 MB:
$ sudo cat /sys/kernel/debug/x86/sgx_nr_all_pages

When running as a TDX guest, there are a number of existing,
privileged instructions that do not work. If the guest kernel
uses these instructions, the hardware generates a #VE.
You can find the list of unsupported instructions in Intel

Currently only root can write files under /proc/pressure. Relax this to
allow tasks running as unprivileged users with CAP_SYS_RESOURCE to be
able to write to these files.
