[ Upstream commit 464de7e ] Use dev_dbg() instead of dev_err() in advk_pcie_check_pio_status(). For example CRS is not an error status, it just says that the request should be retried.

…ridge [ Upstream commit d419052 ] Commit 43f5c77 ("PCI: aardvark: Fix reporting CRS value") started using CRSSVE flag for handling CRS responses. PCI_EXP_RTCTL_CRSSVE flag is stored only in emulated config space buffer and there is handler for PCI_EXP_RTCTL register. So every read operation from config space automatically clears CRSSVE flag as it is not defined in PCI_EXP_RTCTL read handler. Fix this by reading current CRSSVE bit flag from emulated space buffer and appending it to PCI_EXP_RTCTL read response.

[ Upstream commit 2667f6b ] I have a ST1633 touch controller which fails to probe due to a timeout waiting for the controller to become ready. Increasing the minimum delay to 100ms ensures that the probe sequence completes successfully. The ST1633 datasheet says nothing about the maximum delay here and the ST1232 I2C protocol document says "wait until" with no notion of a timeout. Since this only runs once during probe, being generous with the timout seems reasonable and most likely the device will become ready eventually. (It may be worth noting that I saw this issue with a PREEMPT_RT patched kernel which probably has tighter wakeups from usleep_range() than other preemption models.)

…tion [ Upstream commit 4caab28 ] The condition register PCI_RCV_INTX is used in irq_mask() and irq_unmask() callbacks. Accesses to register can occur at the same time without a lock. Add a lock into each callback to prevent the issue. And INTX mask and unmask fields in PCL_RCV_INTX register should only be set/reset for each bit. Clearing by PCL_RCV_INTX_ALL_MASK should be removed. INTX status fields in PCL_RCV_INTX register only indicates each INTX interrupt status, so the handler can't clear by writing 1 to the field. The status is expected to be cleared by the interrupt origin. The ack function has no meaning, so should remove it.

[ Upstream commit e7e1e88 ] Before the `callback_result` callback was introduced drivers coded their invocation to the callback in a similar way to: if (cb->callback) { spin_unlock(&dma->lock); cb->callback(cb->callback_param); spin_lock(&dma->lock); } With the introduction of `callback_result` two helpers where introduced to transparently handle both types of callbacks. And drivers where updated to look like this: if (dmaengine_desc_callback_valid(cb)) { spin_unlock(&dma->lock); dmaengine_desc_callback_invoke(cb, ...); spin_lock(&dma->lock); } dmaengine_desc_callback_invoke() correctly handles both `callback_result` and `callback`. But we forgot to update the dmaengine_desc_callback_valid() function to check for `callback_result`.

[ Upstream commit 98da010 ] Fault triggers on ioread32() when pci driver unbind is envoked. The placement of idxd sub-driver removal causes the probing of the device mmio region after the mmio mapping being torn down. The driver needs the sub-drivers to be unbound but not release the idxd context until all shutdown activities has been done. Move the sub-driver unregistering up before the remove() calls shutdown(). But take a device ref on the idxd->conf_dev so that the memory does not get freed in ->release(). When all cleanup activities has been done, release the ref to allow the idxd memory to be freed.

[ Upstream commit ce0ee4e ] Today the sh code allocates memory the first time a process uses the fpu. If that memory allocation fails, kill the affected task with force_sig(SIGKILL) rather than do_group_exit(SIGKILL). Calling do_group_exit from an exception handler can potentially lead to dead locks as do_group_exit is not designed to be called from interrupt context. Instead use force_sig(SIGKILL) to kill the userspace process. Sending signals in general and force_sig in particular has been tested from interrupt context so there should be no problems.

commit 3ec18fc upstream. commit 8779e05 ("parisc: Fix ptrace check on syscall return") fixed testing of TI_FLAGS. This uncovered a bug in the test mask. syscall_restore_rfi is only used when the kernel needs to exit to usespace with single or block stepping and the recovery counter enabled. The test however used _TIF_SYSCALL_TRACE_MASK, which includes a lot of bits that shouldn't be tested here. Fix this by using TIF_SINGLESTEP and TIF_BLOCKSTEP directly. I encountered this bug by enabling syscall tracepoints. Both in qemu and on real hardware. As soon as i enabled the tracepoint (sys_exit_read, but i guess it doesn't really matter which one), i got random page faults in userspace almost immediately.

commit 4716023 upstream. PEBS PERF_SAMPLE_PHYS_ADDR events use perf_virt_to_phys() to convert PMU sampled virtual addresses to physical using get_user_page_fast_only() and page_to_phys(). Some get_user_page_fast_only() error cases return false, indicating no page reference, but still initialize the output page pointer with an unreferenced page. In these error cases perf_virt_to_phys() calls put_page(). This causes page reference count underflow, which can lead to unintentional page sharing. Fix perf_virt_to_phys() to only put_page() if get_user_page_fast_only() returns a referenced page.
