From 296f781a4b7801ad9c1c0219f9e87b6c25e196fe Mon Sep 17 00:00:00 2001 From: Andy Lutomirski Date: Tue, 26 Apr 2016 12:23:29 -0700 Subject: x86/asm/64: Rename thread_struct's fs and gs to fsbase and gsbase Unlike ds and es, these are base addresses, not selectors. Rename them so their meaning is more obvious. On x86_32, the field is still called fs. Fixing that could make sense as a future cleanup.
