Hello! This series provides /proc interfaces parallel to /proc/cmdline that provide only those kernel boot parameters that were provided by the bootloader (/proc/cmdline_load) and only those parameters that were embedded in the kernel image (/proc/cmdline_image, in boot-config format). This is especially important when these parameters are presented to the boot loader by automation that might gather them from diverse sources, and also when a kexec-based reboot process pulls the kernel boot parameters from /proc. If such a reboot process uses /proc/cmdline, the kernel parameters from the image are replicated on every reboot, which can be frustrating when the new kernel has different embedded kernel boot parameters. Why put these in /proc? Because they is quite similar to /proc/cmdline, so it makes sense to put it in the same place that /proc/cmdline is located. 1. fs/proc: Add /proc/cmdline_load for boot loader arguments. 2. fs/proc: Add /proc/cmdline_image for embedded arguments.
