Revision ab6b1d1fc4aae6b8bd6fb1422405568094c9b40f authored by Thiago Jung Bauermann on 20 December 2016, 00:22:45 UTC, committed by Linus Torvalds on 20 December 2016, 17:48:44 UTC
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.

	  Enables the display of the minimum amount of free stack which each
	  task has ever had available in the sysrq-T and sysrq-P debug output.

	  This option will slow down process creation somewhat.

	help
	  Enable early printk on console
	  This is useful for kernel debugging when your machine crashes very
	  early before the console code is initialized.
	  You should normally say N here, unless you want to debug such a crash.
