Raspberry Pi 4's firmware will take care of updating those, but only if a certain alias is found in the device tree. So, move emmc2 into its own bus, so as not to pollute other devices with dma-ranges changes and create the emmc2bus alias. Based in Phil ELwell's downstream implementation.

Discussing the YAML validation schema with the DT maintainers it came out that a bus named "smb@80000000" is not really accepted, and the schema was written to name the static memory bus just "bus@80000000". This change is necessary for the schema to kick in and validate these device trees, else the schema gets ignored.

2020-03-01KVM: VMX: check descriptor table exits on instruction emulationOliver Upton1-0/+15
KVM emulates UMIP on hardware that doesn't support it by setting the 'descriptor table exiting' VM-execution control and performing instruction emulation. When running nested, this emulation is broken as KVM refuses to emulate L2 instructions by default. Correct this regression by allowing the emulation of descriptor table instructions if L1 hasn't requested 'descriptor table exiting'.

2020-03-01ext4: potential crash on allocation error in ext4_alloc_flex_bg_array()Dan Carpenter1-3/+3
If sbi->s_flex_groups_allocated is zero and the first allocation fails then this code will crash. The problem is that "i--" will set "i" to -1 but when we compare "i >= sbi->s_flex_groups_allocated" then the -1 is type promoted to unsigned and becomes UINT_MAX. Since UINT_MAX is more than zero, the condition is true so we call kvfree(new_groups[-1]). The loop will carry on freeing invalid memory until it crashes.

2020-02-29macintosh: therm_windtunnel: fix regression when instantiating devicesWolfram Sang1-21/+31
Removing attach_adapter from this driver caused a regression for at least some machines. Those machines had the sensors described in their DT, too, so they didn't need manual creation of the sensor devices. The old code worked, though, because manual creation came first. Creation of DT devices then failed later and caused error logs, but the sensors worked nonetheless because of the manually created devices. When removing attach_adaper, manual creation now comes later and loses the race. The sensor devices were already registered via DT, yet with another binding, so the driver could not be bound to it. This fix refactors the code to remove the race and only manually creates devices if there are no DT nodes present. Also, the DT binding is updated to match both, the DT and manually created devices. Because we don't know which device creation will be used at runtime, the code to start the kthread is moved to do_probe() which will be called by both methods.
