CONFIG_HOTPLUG is a very old option, back when we had static systems and it was odd that any type of device would be removed or added after the system had started up. It is quite hard to disable it these days, and even if you do, it only saves you about 200 bytes. However, if it is disabled, lots of bugs show up because it is almost never tested if the option is disabled. This is a step to eventually just remove the option entirely, which will clean up all of the devinit* variable and function pointer options, that everyone (myself include) ends up getting wrong eventually, causing real problems when memory segments are removed yet we don't expect them to be.

External connector devices that decides connection information based on ADC values may use adc-jack device driver. The user simply needs to provide a table of adc range and connection states. Then, extcon framework will automatically notify others. Changes in V1: added Lars-Peter Clausen suggested changes: Using macros to get rid of boiler plate code such as devm_kzalloc and module_platform_driver.Other changes suggested are related to coding guidelines. Changes in V2: Removed some unnecessary checks and changed the way we are un-regitering extcon and freeing the irq while removing. Changes in V3: Renamed the files to comply with extcon naming. Changes in V4: Added the cancel_work_sync during removing of driver. Changes in V5: Added the dependency of IIO in Kconfig. Changes in V6: Some nitpicks related to naming. Changes in this version: V6 patch version patch broke the build: ERROR: "extcon_cable_name" [drivers/extcon/extcon-adc-jack.ko] undefined! Fixed it in this version.

This is part of the IP injection protocol in that the host expects this field to reflect what addresses (address families) are currently bound to the interface. The KVP daemon is currently collecting this information and sending it to the kernel component. I had overlooked copying this and sending it back to the host. This patch addresses this issue.

Commit e6b42eb6 "memory: emif: add device tree support to emif driver" added drivers/memory/of_memory.c, which references tables defined in lib/jedec_ddr_data.c. of_memory.c is compiled when CONFIG_OF, whereas jedec_ddr_data.c is compiled when CONFIG_DDR. This breaks the build when CONFIG_OF is defined but not CONFIG_DDR: drivers/built-in.o: In function `of_get_ddr_timings': drivers/memory/of_memory.c:138: undefined reference to `lpddr2_jedec_timings' drivers/built-in.o: In function `of_get_min_tck': drivers/memory/of_memory.c:62: undefined reference to `lpddr2_jedec_min_tck' make: *** [vmlinux] Error 1 To solve this, only compile of_memory.c when CONFIG_OF && CONFIG_DDR, otherwise, stub out the functions.

There are two reasons we need to use x86_hyper instead of query_hypervisor_presence(): - Not only hyperv but also other hypervisors such as kvm would set X86_FEATURE_HYTPERVISOR, so query_hypervisor_presence() will return true even in kvm. This may cause extra delay of 5 seconds before failing the probing in kvm guest. - The hypervisor has been detected in init_hypervisor(), so no need to do the work again.
