I have few message on device boot about missing files or directories:
[ 3.052514] init: write_file: Unable to open '/proc/cpu/alignment': No such file or directory
[ 4.931333] init: write_file: Unable to open '/proc/sys/vm/min_free_order_shift': No such file or directory
write /proc/cpu/alignment 4
Filesystem under '/proc' is special in sence that all of its files are "created" by the kernel, and user cannot create files there.
This is pseudo-filesystem: its files are not stored on hard disk, but exist only in RAM and reflect system properties. Writing into this files changes properties in a special way. You cannot create new properties there.
