arm64: mm: update CONTEXTIDR register to contain PID of current process This patch is a port of 575320d62 ("ARM: 7445/1: mm: update CONTEXTIDR register to contain PID of current process") from ARM that introduces a new Kconfig option which, when enabled, causes the kernel to write the PID of the current task into the CONTEXTIDR register on context switch. This is useful when analysing hardware trace, since writes to this register can be configured to emit an event into the trace stream.

efi: arm64: Add vmlinux debug link to the Image binary When building with debugging symbols, take the absolute path to the vmlinux binary and add it to the special PE/COFF debug table entry. This allows a debug EFI build to find the vmlinux binary, which is very helpful in debugging, given that the offset where the Image is first loaded by EFI is highly unpredictable. On implementations of UEFI that choose to implement it, this information is exposed via the EFI debug support table, which is a UEFI configuration table that is accessible both by the firmware at boot time and by the OS at runtime, and lists all PE/COFF images loaded by the system. The format of the NB10 Codeview entry is based on the definition used by EDK2, which is our primary reference when it comes to the use of PE/COFF in the context of UEFI firmware.

arm64: relocation testing module This module tests the module loader's ELF relocation processing routines. When loaded, it logs output like below.

coresight: moving to new "hwtracing" directory Keeping drivers related to HW tracing on ARM, i.e coresight, under "drivers/coresight" doesn't make sense when other architectures start rolling out technologies of the same nature. As such creating a new "drivers/hwtracing" directory where all drivers of the same kind can reside, reducing namespace pollution under "drivers/".
