2021-04-12s390/pci: separate zbus creation from scanningNiklas Schnelle
In the existing code the creation of the PCI bus and the scanning of function zero all happens in zpci_scan_bus(). This in turn requires functions to be enabled and their resources to be available before the PCI bus is even created. This not only means that functions are enabled long before they are actually made available to the common PCI subsystem. In case of functions with non-zero devfn which appeared before the function with devfn zero they can wait arbitrarily long in this enabled but not scanned state. Fix this by separating the creation of the PCI bus from scanning it and only prepare, that is enable and setup MMIO bus resources, functions just before they are scanned. As they may be scanned multiple times track if we already created resources in the zdev.

2021-04-12s390/pci: introduce zpci_bus_scan_device()Niklas Schnelle
To match zpci_bus_scan_device() and the PCI common code terminology and to remove some code duplication, we pull the multiple uses of pci_scan_single_device() into a function. For now this has the side effect of adding each device to the PCI bus separately and locking and unlocking the rescan/remove lock for each instead of just once per bus. This is clearly less efficient but provides a correct intermediate behavior until a follow on change does both the adding and scanning only once per bus.

2021-04-12s390/entry: save the caller of psw_idleVasily Gorbik
Currently psw_idle does not allocate a stack frame and does not save its r14 and r15 into the save area. Even though this is valid from call ABI point of view, because psw_idle does not make any calls explicitly, in reality psw_idle is an entry point for controlled transition into serving interrupts. So, in practice, psw_idle stack frame is analyzed during stack unwinding. Depending on build options that r14 slot in the save area of psw_idle might either contain a value saved by previous sibling call or complete garbage.

2021-04-12s390/entry: avoid setting up backchain in ext|io handlersVasily Gorbik
Currently when interrupt arrives to cpu while in kernel context INT_HANDLER macro (used for ext_int_handler and io_int_handler) allocates new stack frame and pt_regs on the kernel stack and sets up the backchain to jump over the pt_regs to the frame which has been interrupted. This is not ideal to two reasons: 1. This hides the fact that kernel stack contains interrupt frame in it and hence breaks arch_stack_walk_reliable(), which needs to know that to guarantee "reliability" and checks that there are no pt_regs on the way. 2. It breaks the backchain unwinder logic, which assumes that the next stack frame after an interrupt frame is reliable, while it is not. In some cases (when r14 contains garbage) this leads to early unwinding termination with an error, instead of marking frame as unreliable and continuing. To address that, only set backchain to 0.

2021-04-12dmaengine: Fix a double free in dma_async_device_registerLv Yunlong
In the first list_for_each_entry() macro of dma_async_device_register, it gets the chan from list and calls __dma_async_device_channel_register (..,chan). We can see that chan->local is allocated by alloc_percpu() and it is freed chan->local by free_percpu(chan->local) when __dma_async_device_channel_register() failed. But after __dma_async_device_channel_register() failed, the caller will goto err_out and freed the chan->local in the second time by free_percpu(). The cause of this problem is forget to set chan->local to NULL when chan->local was freed in __dma_async_device_channel_register(). My patch sets chan->local to NULL when the callee failed to avoid double free.

2021-04-12mmc: core: Use userland specified timeout value for eMMC sanitizeBean Huo
As the density increases, the 4-minute timeout value for sanitize is no longer feasible. At the same time, devices of different densities have different timeout values, which makes it difficult to use a common timeout value. Therefore, let's pass down the userland-specified sanitize timeout value so it can be used.

The rxchannel id is updated by the driver using the port no value, but this does not ensure that the value is correct. So now rx channel value is obtained from etoc channel map value.

The return from the call to platform_get_irq() is int, it can be a negative error code, however this is being assigned to an unsigned int variable 'irq', so making 'irq' an int, and change the position to keep the code format. ./drivers/ata/pata_ixp4xx_cf.c:168:5-8: WARNING: Unsigned expression compared with zero: irq > 0 Signed-off-by: Junlin Yang <yangjunlin@yulong.com> Link: https://lore.kernel.org/r/20210409135426.1773-1-angkery@163.com Signed-off-by: Jens Axboe <axboe@kernel.dk>

2021-04-11io_uring: optimise fill_event() by inliningPavel Begunkov
There are three cases where we much care about performance of io_cqring_fill_event() -- flushing inline completions, iopoll and io_req_complete_post(). Inline a hot part of fill_event() into them. All others are not as important and we don't want to bloat binary for them, so add a noinline version of the function for all other use use cases. nops test(batch=32): 16.932 vs 17.822 KIOPS Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Link: https://lore.kernel.org/r/a11d59424bf4417aca33f5ec21008bb3b0ebd11e.1618101759.git.asml.silence@gmail.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
