flush_old_exec() has already done that. Back on 2011 a bunch of
instances like that had been kicked out, but that hadn't taken
care of then-out-of-tree architectures, obviously, and they served
as reinfection vector...

Pull Hexagon fixes from Richard Kuo:
"Changes for the Hexagon architecture (and one touching OpenRISC).
They include various fixes to make use of additional arch features and
cleanups. The largest functional change is a cleanup of the signal
and event return paths"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rkuo/linux-hexagon-kernel: (32 commits)
Hexagon: add v4 CS regs to core copyout macro
Hexagon: use correct translation for VMALLOC_START
Hexagon: use correct translations for DMA mappings
Hexagon: fix return value for notify_resume case in do_work_pending
Hexagon: fix signal number for user mem faults
Hexagon: remove two Kconfig entries
arch: remove CONFIG_GENERIC_FIND_NEXT_BIT again
Hexagon: update copyright dates
Hexagon: add translation types for __vmnewmap
Hexagon: fix signal.c compile error
Hexagon: break up user fn/arg register setting
Hexagon: use generic sys_fork, sys_vfork, and sys_clone
Hexagon: fix psp/sp macro
Hexagon: fix up int enable/disable at ret_from_fork
Hexagon: add IOMEM and _relaxed IO macros
Hexagon: switch to using the device type for IO mappings
Hexagon: don't print info for offline CPU's
Hexagon: add support for single-stepping (v4+)
Hexagon: use correct work mask when checking for more work
Hexagon: add support for additional exceptions
...
This fixes the return value of sigreturn and moves the work pending check
into a c routine for readability and fixes the loop for multiple pending
signals. Based on feedback from Al Viro.

The core now has a threadinfo allocator which uses a kmemcache when
THREAD_SIZE < PAGE_SIZE.
