hv: Add hyperv.h to uapi headers This patch adds the hyperv.h header to the uapi folder, and adds it to the Kbuild file. Doing this enables compiling userspace Hyper-V tools using the installed headers. Version 2: Split UAPI parts into new header, instead of duplicating.

Drivers: hv: Implement the file copy service Implement the file copy service for Linux guests on Hyper-V. This permits the host to copy a file (over VMBUS) into the guest. This facility is part of "guest integration services" supported on the Windows platform. Here is a link that provides additional details on this functionality: http://technet.microsoft.com/en-us/library/dn464282.aspx In V1 version of the patch I have addressed comments from Olaf Hering <olaf@aepfle.de> and Dan Carpenter <dan.carpenter@oracle.com> In V2 version of this patch I did some minor cleanup (making some globals static). In V4 version of the patch I have addressed all of Olaf's most recent set of comments/concerns. In V5 version of the patch I had addressed Greg's most recent comments. I would like to thank Greg for suggesting that I use misc device; it has significantly simplified the code. In V6 version of the patch I have cleaned up error message based on Olaf's comments. I have also rebased the patch based on the current tip. In this version of the patch, I have addressed the latest comments from Greg. Signed-off-by: K. Y.

Drivers: hv: util: make struct hv_do_fcopy match Hyper-V host messages An attempt to fix fcopy on i586 (bc5a5b0 Drivers: hv: util: Properly pack the data for file copy functionality) led to a regression on x86_64 (and actually didn't fix i586 breakage). Fcopy messages from Hyper-V host come in the following format: struct do_fcopy_hdr | 36 bytes 0000 | 4 bytes offset | 8 bytes size | 4 bytes data | 6144 bytes On x86_64 struct hv_do_fcopy matched this format without ' __attribute__((packed))' and on i586 adding ' __attribute__((packed))' to it doesn't change anything. Keep the structure packed and add padding to match re reality. Tested both i586 and x86_64 on Hyper-V Server 2012 R2. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: K. Y.
