2021-12-02pinctrl/rockchip: fix gpio device creationJohn Keeping1-1/+1
GPIO nodes are not themselves busses, so passing rockchip_bank_match here is wrong. Passing NULL instead uses the standard bus match table which is more appropriate. devm_of_platform_populate() shows that this is the normal way to call of_platform_populate() from a device driver, so in order to match that more closely also add the pinctrl device as the parent for the newly created GPIO controllers. Specifically, using the wrong match here can break dynamic GPIO hogs as marking the GPIO bank as a bus means that of_platform_notify() will set OF_POPULATED on new child nodes and if this happens before of_gpio_notify() is called then the new hog will be skipped as OF_POPULATED is already set.

2021-11-22pinctrl: qcom: Add egpio feature supportPrasad Sodagudi2-2/+23
egpio is a scheme which allows special power Island Domain IOs (LPASS,SSC) to be reused as regular chip GPIOs by muxing regular TLMM functions with Island Domain functions. With this scheme, an IO can be controlled both by the cpu running linux and the Island processor. This provides great flexibility to re-purpose the Island IOs for regular TLMM usecases. 2 new bits are added to ctl_reg, egpio_present is a read only bit which shows if egpio feature is available or not on a given gpio. egpio_enable is the read/write bit and only effective if egpio_present is 1. Once its set, the Island IO is controlled from Chip TLMM. egpio_enable when set to 0 means the GPIO is used as Island Domain IO. To support this we add a new function 'egpio' which can be used to set the egpio_enable to 0, for any other TLMM controlled functions we set the egpio_enable to 1.

2021-11-20proc/vmcore: fix clearing user buffer by properly using clear_user()David Hildenbrand1-8/+12
To clear a user buffer we cannot simply use memset, we have to use clear_user().

In the x86-64 variant of clear_user(), SMAP is properly handled via clac()+stac(). To fix, properly use clear_user() when we're dealing with a user buffer.

2021-11-20kmap_local: don't assume kmap PTEs are linear arrays in memoryArd Biesheuvel3-11/+25
The kmap_local conversion broke the ARM architecture, because the new code assumes that all PTEs used for creating kmaps form a linear array in memory, and uses array indexing to look up the kmap PTE belonging to a certain kmap index. On ARM, this cannot work, not only because the PTE pages may be non-adjacent in memory, but also because ARM/!LPAE interleaves hardware entries and extended entries (carrying software-only bits) in a way that is not compatible with array indexing. Fortunately, this only seems to affect configurations with more than 8 CPUs, due to the way the per-CPU kmap slots are organized in memory. Work around this by permitting an architecture to set a Kconfig symbol that signifies that the kmap PTEs do not form a lineary array in memory, and so the only way to locate the appropriate one is to walk the page tables.
