# Merge: 4d8f5f91b8a6 f6581f5b5514
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Tue Jun 11 15:44:45 2019 -1000
# 
#     Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull ptrace fixes from Eric Biederman:
#      "This is just two very minor fixes:
#     
#        - prevent ptrace from reading unitialized kernel memory found twice
#          by syzkaller
#     
#        - restore a missing smp_rmb in ptrace_may_access and add comment tp
#          it so it is not removed by accident again.
#     
#       Apologies for being a little slow about getting this to you, I am
#       still figuring out how to develop with a little baby in the house"
#     
#     * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
#       ptrace: restore smp_rmb() in __ptrace_may_access()
#       signal/ptrace: Don't leak unitialized kernel memory with PTRACE_PEEK_SIGINFO

WARNING: vmlinux.o(.text+0x322a): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()
The function start_here_multiplatform() references
the function __init .early_setup().
This is often because start_here_multiplatform lacks a __init 
annotation or the annotation of .early_setup is wrong.
