Disable write protect when writing #14
Description
It would be useful to be able to disable write protect bit on intel (and its equivalent on arm if there is one), prior to any write operation and enable it again just after writing.
Something like an evar could be added, maybe r2k.disable_writeprotect or something like, and whenever the evar is set to true, disable the WP bit on cr0 prior any writing operation, and set it back after the write.
Do not leave the bit changed after writing, in order to not interfere with normal system operations. Also I would disable preemption during the operation, just to be on the safe side, to avoid being scheduled out, and end up in a different cpu whenever the execution is resumed.
