The reason is that start_shepherd_timer schedules the shepherd work item
which uses vmstat_wq (vmstat_shepherd) before setup_vmstat allocates
that workqueue so if the further initialization takes more than HZ we
might end up scheduling on a NULL vmstat_wq.  This is really unlikely
but not impossible.

Pull "urgent onenand file system corruption fix for n900" from Tony Lindgren:

Last minute urgent pull request to prevent file system corruption
on Nokia N900.

Looks like we have a GPMC bus timing bug that has gone unnoticed
because of bootloader configured registers until few days ago. We
are not detecting the onenand clock rate properly unless we have
CONFIG_OMAP_GPMC_DEBUG set and this causes onenand corruption
that can be easily be reproduced.

There seems to be also an additional bug still lurking around for
onenand corruption. But that is still being investigated and
it does not seem to be GPMC timings related.

Meanwhile, it would be good to get this fix into v4.4 to prevent
wrong timings from corrupting onenand.

  ARM: OMAP2+: Fix onenand rate detection to avoid filesystem corruption

This reverts commit d3805611.

If we end up splitting on the first segment, we don't adjust
the sector count. That results in hitting a BUG() with attempting
to split 0 sectors.

As this is just a performance issue and not a regression since
4.3 release, let's just rever this change. That gives us more
time to test a real fix for 4.5, which would be marked for
stable anyway.

Mark the dra7xx PCI host driver as broken.  This driver was first merged in
v3.17 and has never worked.  Although the driver compiles just fine, it is
missing an essential device reset.  If the driver is included, the kernel
locks up hard shortly after booting, before any console output appears.

 "PeiyangX Qiu reported that if a module fails to load between calling

  The solution is to call ftrace_release_mod() on the failing module in
  the fail path befor do_init_module() is called.  This will remove any
  allocations made for that module, and nothing if ftrace_module_init()
  wasn't called yet for that module.

  Note, once do_init_module() is called, the MODULE_GOING notifiers are
  called for the failed module, which calls into the ftrace code to do
  the proper clean up (basically calling ftrace_release_mod())"

* tag 'trace-v4.4-rc4-4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
  ftrace/module: Call clean up function when module init fails early

If the module init code fails after calling ftrace_module_init() and before
calling do_init_module(), we can suffer from a memory leak. This is because
ftrace_module_init() allocates pages to store the locations that ftrace
hooks are placed in the module text. If do_init_module() fails, it still
calls the MODULE_GOING notifiers which will tell ftrace to do a clean up of
the pages it allocated for the module. But if load_module() fails before
then, the pages allocated by ftrace_module_init() will never be freed.

Call ftrace_release_mod() on the module if load_module() fails before
getting to do_init_module().
