Merge tag 'x86-urgent-2020-12-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"A set of x86 and membarrier fixes:
- Correct a few problems in the x86 and the generic membarrier
implementation. Small corrections for assumptions about visibility
which have turned out not to be true.
- Make the PAT bits for memory encryption correct vs 4K and 2M/1G
page table entries as they are at a different location.
- Fix a concurrency issue in the the local bandwidth readout of
resource control leading to incorrect values
- Fix the ordering of allocating a vector for an interrupt. The order
missed to respect the provided cpumask when the first attempt of
allocating node local in the mask fails. It then tries the node
instead of trying the full provided mask first. This leads to
erroneous error messages and breaking the (user) supplied affinity
request. Reorder it.
- Make the INT3 padding detection in optprobe work correctly"

- * The signal type is GPIO if the signal name has "GPI" as a prefix.
- * strncmp (rather than strcmp) is used to implement the prefix
- * requirement.
+ * We need to differentiate between GPIO and non-GPIO signals to
+ * implement the gpio_request_enable() interface. For better or worse
+ * the ASPEED pinctrl driver uses the expression names to determine
+ * whether an expression will mux a pin for GPIO.
*
- * expr->signal might look like "GPIOB1" in the GPIO case.
- * expr->signal might look like "GPIT0" in the GPI case.
+ * Generally we have the following - A GPIO such as B1 has:
+ *
+ * - expr->signal set to "GPIOB1"
+ * - expr->function set to "GPIOB1"
+ *
+ * Using this fact we can determine whether the provided expression is
+ * a GPIO expression by testing the signal name for the string prefix
+ * "GPIO".
+ *
+ * However, some GPIOs are input-only, and the ASPEED datasheets name
+ * them differently. An input-only GPIO such as T0 has:
+ *
+ * - expr->signal set to "GPIT0"
+ * - expr->function set to "GPIT0"
+ *
+ * It's tempting to generalise the prefix test from "GPIO" to "GPI" to
+ * account for both GPIOs and GPIs, but in doing so we run aground on
+ * another feature:
+ *
+ * Some pins in the ASPEED BMC SoCs have a "pass-through" GPIO
+ * function where the input state of one pin is replicated as the
+ * output state of another (as if they were shorted together - a mux
+ * configuration that is typically enabled by hardware strapping).
+ * This feature allows the BMC to pass e.g. power button state through
+ * to the host while the BMC is yet to boot, but take control of the
+ * button state once the BMC has booted by muxing each pin as a
+ * separate, pin-specific GPIO.
+ *
+ * Conceptually this pass-through mode is a form of GPIO and is named
+ * as such in the datasheets, e.g. "GPID0". This naming similarity
+ * trips us up with the simple GPI-prefixed-signal-name scheme
+ * discussed above, as the pass-through configuration is not what we
+ * want when muxing a pin as GPIO for the GPIO subsystem.
+ *
+ * On e.g. the AST2400, a pass-through function "GPID0" is grouped on
+ * balls A18 and D16, where we have:
+ *
+ * For ball A18:
+ * - expr->signal set to "GPID0IN"
+ * - expr->function set to "GPID0"
+ *
+ * For ball D16:
+ * - expr->signal set to "GPID0OUT"
+ * - expr->function set to "GPID0"
+ *
+ * By contrast, the pin-specific GPIO expressions for the same pins are
+ * as follows:
+ *
+ * For ball A18:
+ * - expr->signal looks like "GPIOD0"
+ * - expr->function looks like "GPIOD0"
+ *
+ * For ball D16:
+ * - expr->signal looks like "GPIOD1"
+ * - expr->function looks like "GPIOD1"
+ *
+ * Testing both the signal _and_ function names gives us the means
+ * differentiate the pass-through GPIO pinmux configuration from the
+ * pin-specific configuration that the GPIO subsystem is after: An
+ * expression is a pin-specific (non-pass-through) GPIO configuration
+ * if the signal prefix is "GPI" and the signal name matches the
