So far, the DT parsing code was only setting up the regular input axes, completely ignoring their multitouch counter parts. Fill them with the same parameters than the regular axes.

On devices with a native portrait screen a landscape touchscreen / digitizer may be used, this happens e.g. on ebook readers. In this case the X and Y axis of the touchscreen are swapped compared to the screen. Add a touchscreen-swapped-x-y property which drivers can use to see if they need to swap the axis to make the touchscreen coordinates match the screen coordinates.

If ->run() fails, it can either free the data structures it allocated, or leave that task to ->free() which will be called on failures. However: md.c calls ->free() even if ->private_data is NULL, which causes problems in some personalities. raid0.c frees the data, but doesn't clear ->private_data, which will become a problem when we fix md.c So better fix both these issues at once.

由 Will Deacon 提交于
init_mm isn't a normal mm: it has swapper_pg_dir as its pgd (which contains kernel mappings) and is used as the active_mm for the idle thread. When restoring the pgd after an EFI call, we write current->active_mm into TTBR0. If the current task is actually the idle thread (e.g. when initialising the EFI RTC before entering userspace), then the TLB can erroneously populate itself with junk global entries as a result of speculative table walks. When we do eventually return to userspace, the task can end up hitting these junk mappings leading to lockups, corruption or crashes. This patch fixes the problem in the same way as the CPU suspend code by ensuring that we never switch to the init_mm in efi_set_pgd and instead point TTBR0 at the zero page. A check is also added to cpu_switch_mm to BUG if we get passed swapper_pg_dir.

由 Rafael J. Wysocki 提交于
Commit b4b55cda (Refine the way to release PCI IRQ resources) introduced a regression in the PCI IRQ resource management by causing the IRQ resource of a device, established when pci_enabled_device() is called on a fully disabled device, to be released when the driver is unbound from the device, regardless of the enable_cnt. This leads to the situation that an ill-behaved driver can now make a device unusable to subsequent drivers by an imbalance in their use of pci_enable/disable_device(). That is a serious problem for secondary drivers like vfio-pci, which are innocent of the transgressions of the previous driver. Since the solution of this problem is not immediate and requires further discussion, revert commit b4b55cda and the issue it was supposed to address (a bug related to xen-pciback) will be taken care of in a different way going forward.

A check that rejects a CDB with FUA bit set if no write cache is emulated was added by the following commit: fde9f50f target: Add sanity checks for DPO/FUA bit usage The condition is as follows: if (!dev->dev_attrib.emulate_fua_write || !dev->dev_attrib.emulate_write_cache) However, this check is wrong if the backend device supports WCE but "emulate_write_cache" is disabled. This patch uses se_dev_check_wce() (previously named spc_check_dev_wce) to invoke transport->get_write_cache() if the device has a write cache or check the "emulate_write_cache" attribute otherwise.

This patch fixes a NULL pointer dereference triggered by a late target_configure_device() -> alloc_workqueue() failure that results in target_free_device() being called with DF_CONFIGURED already set, which subsequently OOPses in destroy_workqueue() code. Currently this only happens at modprobe target_core_mod time when core_dev_setup_virtual_lun0() -> target_configure_device() fails, and the explicit target_free_device() gets called. To address this bug originally introduced by commit 0fd97ccf, go ahead and move DF_CONFIGURED to end of target_configure_device() code to handle this special failure case.
