Single caller passes GFP_NOFS. We can get rid of the gfpflags_allow_blocking checks as NOFS can block but does not recurse to filesystem through reclaim. Signed-off-by: David Sterba <dsterba@suse.com>

Merge tag 'fixes-for-v4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v4.6-rc5 No more major fixes left. Out of the 6 fixes we have here, 4 are on dwc3. The most important is the memory leak fix in dwc3/debugfs.c. We also have a fix for PHY handling in suspend/resume and a fix for dwc3-omap's error handling. Suspend/resume also had the potential to trigger a NULL pointer dereference on dwc3; that's also fixed now. Our good ol' ffs function gets a use-after-free fix while the generic composite.c layer has a robustness fix by making sure reserved fields of a possible SSP device capability descriptor is cleared to 0.

Huge pages are not normally available to PV guests. Not suppressing hugetlbfs use results in an endless loop of page faults when user mode code tries to access a hugetlbfs mapped area (since the hypervisor denies such PTEs to be created, but error indications can't be propagated out of xen_set_pte_at(), just like for various of its siblings), and - once killed in an oops like this: kernel BUG at .../fs/hugetlbfs/inode.c:428! invalid opcode: 0000 [#1] SMP ...

Sebastian Andrzej Siewior authored
The recent introduction of the hotplug thread which invokes the callbacks on the plugged cpu, cased the following regression: If takedown_cpu() fails, then we run into several issues: 1) The rollback of the target cpu states is not invoked. That leaves the smp threads and the hotplug thread in disabled state. 2) notify_online() is executed due to a missing skip_onerr flag. That causes that both CPU_DOWN_FAILED and CPU_ONLINE notifications are invoked which confuses quite some notifiers. 3) The CPU_DOWN_FAILED notification is not invoked on the target CPU. That's not an issue per se, but it is inconsistent and in consequence blocks the patches which rely on these states being invoked on the target CPU and not on the controlling cpu. It also does not preserve the strict call order on rollback which is problematic for the ongoing state machine conversion as well. To fix this we add a rollback flag to the remote callback machinery and invoke the rollback including the CPU_DOWN_FAILED notification on the remote cpu. Further mark the notify online state with 'skip_onerr' so we don't get a double invokation. This workaround will go away once we moved the unplug invocation to the target cpu itself.
