Hi guys,
It's been a long time that I was going to send to Linux the patch with the following changes, but the birth of my first child intervened and caused delays (though can't call them "unexpected" :). Now, if I hear from people "no, no! we are using this feature!" then I will reconsider:
1. Remove ->read() method for /dev/cpu/microcode device node and do not hold a copy of applied microcode chunks in kernel memory. In the days when we had a regular devfs file with a non-zero size this had at least some potential use but now this feature is almost useless and removing it would allow a lot of code cleanup and simplification.
2. remove MICROCODE_IOCFREE ioctl for freeing the copy of held microcode (because there won't be such copy, see 1.)
Please let me know your thoughts.
Kind regards Tigran
