2024-12-02	module: Convert symbol namespace to string literal	Peter Zijlstra
	Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

2024-03-07	cdx: add MSI support for CDX bus	Nipun Gupta
	Add CDX-MSI domain per CDX controller with gic-its domain as a parent, to support MSI for CDX devices. CDX devices allocate MSIs from the CDX domain. Also, introduce APIs to alloc and free IRQs for CDX domain. In CDX subsystem firmware is a controller for all devices and their configuration. CDX bus controller sends all the write_msi_msg commands to firmware running on RPU and the firmware interfaces with actual devices to pass this information to devices Since, CDX controller is the only way to communicate with the Firmware for MSI write info, CDX domain per controller required in contrast to having a CDX domain per device.
