#16966 fixed get_user_pages() interface change backported on OpenSUSE -> fixed in 5.2 and later builds after Nov 3 2017 Dmitri Chubarov
Description

Several changes to the linux kernel memory management interface had been backported on OpenSUSE.

These two patches are

mm/gup: Overload get_user_pages() functions

https://github.com/torvalds/linux/commit/cde70140fed8429acf7a14e2e2cbd3e329036653 and

mm/gup: Remove the macro overload API migration helpers from the get_user*() APIs

https://github.com/torvalds/linux/commit/c12d2da56d0e07d230968ee2305aaa86b93a6832

This leads to the failure of vboxdrv compilation on OpenSUSE Leap 42.3 with the following diagnostics in /var/log/vbox-install.log:

/usr/src/linux-4.4.76-1/include/linux/mm.h:1264:6: note: expected ‘struct vm_area_struct **’ but argument is of type ‘int’
 long get_user_pages(unsigned long start, unsigned long nr_pages,
      ^
/tmp/vbox.0/r0drv/linux/memobj-r0drv-linux.c:1117:33: error: too many arguments to function ‘get_user_pages’
                                 papVMAs);               /* vmas */
                                 ^
In file included from /tmp/vbox.0/r0drv/linux/the-linux-kernel.h:98:0,
                 from /tmp/vbox.0/r0drv/linux/memobj-r0drv-linux.c:31:
/usr/src/linux-4.4.76-1/include/linux/mm.h:1264:6: note: declared here
 long get_user_pages(unsigned long start, unsigned long nr_pages,
      ^

As one can see the kernel version here is 4.4.76-1, however the get_user_pages() interface looks already has the changes from Ingo Molnar that went into the 4.6.y series.

Attached is the vbox-install.log and the mm.h file provided with the distribution.

#16961 fixed Crackling audio on Windows 10 guest Mac host pentagonik galonsky
Description

MacOS 10.12.6 Windows 10 professional, latest

Audio settings started on the default CoreAudio and Intel HD Audio, and I experienced crackling audio. After seeing some similar reports that were solved by using the ICH AC97 driver, I switched to that and installed the drivers in the guest, but that didn't help.

I tried the latest Test Build as of last night as well, which didn't solve the issue (was also confused since the test build seems to be 5.1.25 and release builds 5.1.26)

Will attach logs
