2016-03-09cxl: Move common code away from bare-metal-specific filesChristophe Lombard
Move around some functions which will be accessed from the bare-metal and guest environments. Code in native.c and pci.c is meant to be bare-metal specific. Other files contain code which may be shared with guests.

There is an anonymous struct which is actually used as a bitmap. So convert the struct to a bitmap and change code accordingly where needed. This also allows for a cleanup of set_data_bits and set_ctrl_bits as they can use a common helper now. The helper can also be converted to a for loop instead of doing bit OR. And given it is a for loop now, bit masking (using BIT_MSK) is moved from the callers there too.

2016-02-09misc: mic: MIC VOP BusSudeep Dutt
The Virtio Over PCIe (VOP) bus abstracts the low level hardware details like interrupts and mapping remote memory so that the same VOP driver can work without changes with different MIC host or card drivers as long as the hardware bus operations are implemented. The VOP driver registers itself on the VOP bus. The base PCIe drivers implement the bus ops and register VOP devices on the bus, resulting in the VOP driver being probed with the VOP devices. This allows the VOP functionality to be shared between multiple generations of Intel MIC products.

2016-02-09lkdtm: mark execute_location as noinlineArnd Bergmann
The kernel sometimes fails to link when lkdrm is built-in and compiled with clang: relocation truncated to fit: R_ARM_THM_CALL against `.bss' The reason here is that a relocation from .text to .bss fails to generate a trampoline because .bss is not an executable section. Marking the function 'noinline' turns the relative branch to .bss into an absolute branch to the function argument, and that works fine.

2016-02-09misc: eeprom_93xx46: Fix 16-bit read and write accesses.Cory Tusar
Compatible at93xx46 devices from both Microchip and Atmel expect a word-based address, regardless of whether the device is strapped for 8- or 16-bit operation. However, the offset parameter passed in when reading or writing at a specific location is always specified in terms of bytes. This commit fixes 16-bit read and write accesses by shifting the offset parameter to account for this difference between a byte offset and a word-based address.

2016-02-07misc/bmp085: Enable building as a moduleBen Hutchings
Commit 985087dbcb02 'misc: add support for bmp18x chips to the bmp085 driver' changed the BMP085 config symbol to a boolean. I see no reason why the shared code cannot be built as a module, so change it back to tristate.
