# Merge: 92c1d6522135 318759b4737c
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull force_sig() argument change from Eric Biederman:
#      "A source of error over the years has been that force_sig has taken a
#       task parameter when it is only safe to use force_sig with the current
#       task.
#     
#       The force_sig function is built for delivering synchronous signals
#       such as SIGSEGV where the userspace application caused a synchronous
#       fault (such as a page fault) and the kernel responded with a signal.
#     
#       Because the name force_sig does not make this clear, and because the
#       force_sig takes a task parameter the function force_sig has been
#       abused for sending other kinds of signals over the years. Slowly those
#       have been fixed when the oopses have been tracked down.
#     
#       This set of changes fixes the remaining abusers of force_sig and
#       carefully rips out the task parameter from force_sig and friends
#       making this kind of error almost impossible in the future"

#     * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (27 commits)
#       signal/x86: Move tsk inside of CONFIG_MEMORY_FAILURE in do_sigbus
#       signal: Remove the signal number and task parameters from force_sig_info
#       signal: Factor force_sig_info_to_task out of force_sig_info
#       signal: Generate the siginfo in force_sig
#       signal: Move the computation of force into send_signal and correct it.
#       signal: Properly set TRACE_SIGNAL_LOSE_INFO in __send_signal
#       signal: Remove the task parameter from force_sig_fault
#       signal: Use force_sig_fault_to_task for the two calls that don't deliver to current
#       signal: Explicitly call force_sig_fault on current
#       signal/unicore32: Remove tsk parameter from __do_user_fault
#       signal/arm: Remove tsk parameter from __do_user_fault
