The patch titled
Subject: proc: unsigned file descriptors

proc-unsigned-file-descriptors.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Alexey Dobriyan <adobriyan@xxxxxxxxx>
Subject: proc: unsigned file descriptors
Make struct proc_inode::fd unsigned.
This allows better code generation on x86_64 (less sign extensions).
