include/linux/thermal.h contains definitions for the Thermal generic netlink family, but none of the valuable information relevant to user-space such as the Genl family name, multicast group, version or command set and data types is exported to user-space. Export all the relevant generic netlink information to user-space to make this genl family usable by user-space, and while at it, export THERMAL_NAME_LENGTH since it limits name length for thermal_hwmon devices. Kbuild and MAINTAINERS are also updated accordingly to reflect this new file: include/uapi/linux/thermal.h.

The driver calls spin_lock_irqsave during DTS interrupt. The interrupt handle then calls thermal_zone_device_update which implicitly calls a sleep function and produce the following bug: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:97 in_atomic(): 1, irqs_disabled(): 1, pid: 920, name: irq/86-soc_dts CPU: 0 PID: 920 Comm: irq/86-soc_dts Tainted: G E 3.17.0-rc2+ #1 Hardware name: Intel Corp.

INT3400 currently supports only one policy, which can't be changed. This change exports all available policies (uuids) to user space and allow this to be changed. It introduces an attribute group uuids in INT3400 platform driver. There are two attributes exposed: - available_uuids - current_uuid User space can set current_uuid via this interface to one of the available uuids. The uuid change is communicated to firmware, only when the current zone mode is changed to "enabled". So the ideal sequence should be - set INT3400 zone mode to "disabled" - change current_uuid - set INT3400 zone mode to "enabled" Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

There is a potential race when probing the TLB in TLBL/M/S exception handlers for a matching entry. Between the time we hit a TLBL/S/M exception and the time we get to execute the TLBP instruction, the HTW may have replaced the TLB entry we are interested in hence the TLB probe may fail. However, in the existing handlers, we never checked the status of the TLBP (ie check the result in the C0/Index register). We fix this by adding such a check when the core implements the HTW. If we couldn't find a matching entry, we return back and try again.
