2016-12-20	powerpc: ima: send the kexec buffer to the next kernel	Thiago Jung Bauermann	1	-1/+1
	The IMA kexec buffer allows the currently running kernel to pass the measurement list via a kexec segment to the kernel that will be kexec'd. This is the architecture-specific part of setting up the IMA kexec buffer for the next kernel. It will be used in the next patch.

2016-11-30	powerpc: Add support code for kexec_file_load()	Thiago Jung Bauermann	1	-0/+663
	This patch adds the support code needed for implementing kexec_file_load() on powerpc. This consists of functions to load the ELF kernel, either big or little endian, and setup the purgatory enviroment which switches from the first kernel to the second kernel. None of this code is built yet, as it depends on CONFIG_KEXEC_FILE which we have not yet defined. Although we could define CONFIG_KEXEC_FILE in this patch, we'd then have a window in history where the kconfig symbol is present but the syscall is not, which would be awkward.
