ohci_shutdown() disables all the interrupt and rh_state is set to OHCI_RH_HALTED. In other hand, ohci_irq() is possible to enable OHCI_INTR_SF and OHCI_INTR_MIE on ohci_irq(). Note that OHCI_INTR_SF is possible to be set by start_ed_unlink() which is called: ohci_irq() -> process_done_list() -> takeback_td() -> start_ed_unlink()
So, ohci_irq() has the following condition, the issue happens by &ohci->regs->intrenable = OHCI_INTR_MIE | OHCI_INTR_SF and ohci->rh_state = OHCI_RH_HALTED:
/* interrupt for some other device? */ if (ints == 0 || unlikely(ohci->rh_state == OHCI_RH_HALTED)) return IRQ_NOTMINE;
To fix the issue, ohci_shutdown() holds the spin lock while disabling the interruption and changing the rh_state flag to prevent reenable the OHCI_INTR_MIE unexpectedly. Note that io_watchdog_func() also calls the ohci_shutdown() and it already held the spin lock, so that the patch makes a new function as _ohci_shutdown().
This patch is inspired by a Renesas R-Car Gen3 BSP patch from Tho Vu.

usb: add a HCD_DMA flag instead of guestimating DMA capabilities
The usb core is the only major place in the kernel that checks for a non-NULL device dma_mask to see if a device is DMA capable. This is generally a bad idea, as all major busses always set up a DMA mask, even if the device is not DMA capable - in fact bus layers like PCI can't even know if a device is DMA capable at enumeration time. This leads to lots of workaround in HCD drivers, and also prevented us from setting up a DMA mask for platform devices by default last time we tried.
Replace this guess with an explicit HCD_DMA that is set by drivers that appear to have DMA support.

usb: host: Fix excessive alignment restriction for local memory allocations
The PAGE_SHIFT alignment restriction to devm_gen_pool_create() quickly exhaust local memory because most allocations are much smaller than PAGE_SIZE. This causes USB device failures such as
usb 1-2.1: reset full-speed USB device number 4 using sm501-usb sd 1:0:0:0: [sda] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x03 driverbyte=0x00 sd 1:0:0:0: [sda] tag#0 CDB: opcode=0x28 28 00 00 00 08 7c 00 00 f0 00 print_req_error: I/O error, dev sda, sector 2172 flags 80700
when trying to boot from the SM501 USB controller on SH4 with QEMU.
Align allocations as required but not necessarily much more than that. The HCCA, TD and ED structures align with 256, 32 and 16 byte memory boundaries, as specified by the Open HCI[1]. The min_alloc_order argument to devm_gen_pool_create is now somewhat arbitrarily set to 4 (16 bytes). Perhaps it could be somewhat lower for general buffer allocations.

USB: use genalloc for USB HCs with local memory
For HCs that have local memory, replace the current DMA API usage with a genalloc generic allocator to manage the mappings for these devices. To help users, introduce a new HCD API, usb_hcd_setup_local_mem() that will setup up the genalloc backing up the device local memory. It will be used in subsequent patches. This is in preparation for dropping the existing "coherent" dma mem declaration APIs. The current implementation was relying on a short circuit in the DMA API that in the end, was acting as an allocator for these type of devices.

ohci-hcd: Fix race condition caused by ohci_urb_enqueue() and io_watchdog_func()
Running io_watchdog_func() while ohci_urb_enqueue() is running can cause a race condition where ohci->prev_frame_no is corrupted and the watchdog can mis-detect following error:
ohci-platform 664a0800.usb: frame counter not updating; disabled ohci-platform 664a0800.usb: HC died; cleaning up
Specifically, following scenario causes a race condition:
1. ohci_urb_enqueue() calls spin_lock_irqsave(&ohci->lock, flags) and enters the critical section 2. ohci_urb_enqueue() calls timer_pending(&ohci->io_watchdog) and it returns false 3. ohci_urb_enqueue() sets ohci->prev_frame_no to a frame number read by ohci_frame_no(ohci) 4. ohci_urb_enqueue() schedules io_watchdog_func() with mod_timer() 5. ohci_urb_enqueue() calls spin_unlock_irqrestore(&ohci->lock, flags) and exits the critical section 6. Later, ohci_urb_enqueue() is called 7. ohci_urb_enqueue() calls spin_lock_irqsave(&ohci->lock, flags) and enters the critical section 8. The timer scheduled on step 4 expires and io_watchdog_func() runs 9. io_watchdog_func() calls spin_lock_irqsave(&ohci->lock, flags) and waits on it because ohci_urb_enqueue() is already in the critical section on step 7 10. ohci_urb_enqueue() calls timer_pending(&ohci->io_watchdog) and it returns false 11. ohci_urb_enqueue() sets ohci->prev_frame_no to new frame number read by ohci_frame_no(ohci) because the frame number proceeded between step 3 and 6 12. ohci_urb_enqueue() schedules io_watchdog_func() with mod_timer() 13. ohci_urb_enqueue() calls spin_unlock_irqrestore(&ohci->lock, flags) and exits the critical section, then wake up io_watchdog_func() which is waiting on step 9 14. io_watchdog_func() enters the critical section 15. io_watchdog_func() calls ohci_frame_no(ohci) and set frame_no variable to the frame number 16. io_watchdog_func() compares frame_no and ohci->prev_frame_no
On step 16, because this calling of io_watchdog_func() is scheduled on step 4, the frame number set in ohci->prev_frame_no is expected to the number set on step 3. However, ohci->prev_frame_no is overwritten on step 11. Because step 16 is executed soon after step 11, the frame number might not proceed, so ohci->prev_frame_no must equals to frame_no.
To address above scenario, this patch introduces a special sentinel value IO_WATCHDOG_OFF and set this value to ohci->prev_frame_no when the watchdog is not pending or running. When ohci_urb_enqueue() schedules the watchdog (step 4 and 12 above), it compares ohci->prev_frame_no to IO_WATCHDOG_OFF so that ohci->prev_frame_no is not overwritten while io_watchdog_func() is running.

treewide: setup_timer() -> timer_setup()
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations.
Casting from unsigned long:
void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr);
and forced object casts:
void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);
become:
void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0);
Direct function assignments:
void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback;
have a temporary cast added, along with converting the args:
void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;
And finally, callbacks without a data assignment:
void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0);
have their argument renamed to verify they're unused during conversion:
void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0);
The conversion is done with the following Coccinelle script:
spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci

USB: add SPDX identifiers to all remaining files in drivers/usb/
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses.
Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE()
Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output.
For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn.
However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script:
---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE()
// $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch

ohci-pci: add qemu quirk
On a loaded virtualization host (dozen guests booting at the same time) it may happen that the ohci controller emulation doesn't manage to do timely frame processing, with the result that the io watchdog fires and considers the controller being dead, even though it's only the emulation being unusual slow due to the load peak.
So, add a quirk for qemu and don't use the watchdog in case we figure we are running on emulated ohci. The virtual ohci controller masquerades as apple ohci controller, but we can identify it by subsystem id.

In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.
