Subject: [PATCH] virt: vbox: Fix VBGL_IOCTL_VMMDEV_REQUEST_BIG and _LOG req
numbers to match upstream
Until this commit the mainline kernel version (this version) of the
vboxguest module contained a bug where it defined
VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG using
_IOC(_IOC_READ | _IOC_WRITE, 'V', ...) instead of
_IO(V, ...) as the out of tree VirtualBox upstream version does.
Since the VirtualBox userspace bits are always built against VirtualBox
upstream's headers, this means that so far the mainline kernel version
of the vboxguest module has been failing these 2 ioctls with -ENOTTY.
I guess that VBGL_IOCTL_VMMDEV_REQUEST_BIG is never used causing us to
not hit that one and sofar the vboxguest driver has failed to actually
log any log messages passed it through VBGL_IOCTL_LOG.
This commit changes the VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG
defines to match the out of tree VirtualBox upstream vboxguest version,
while keeping compatibility with the old wrong request defines so as
to not break the kernel ABI in case someone has been using the old
request defines.

Subject: [PATCH] virt: vbox: Fix guest capabilities mask check
Check the passed in capabilities against VMMDEV_GUEST_CAPABILITIES_MASK
instead of against VMMDEV_EVENT_VALID_EVENT_MASK.
This tightens the allowed mask from 0x7ff to 0x7.

Subject: [PATCH] copy_xstate_to_kernel: Fix typo which caused GDB regression

This commit fixes a regression encountered while running the
gdb.base/corefile.exp test in GDB's test suite.
In my testing, the typo prevented the sw_reserved field of struct
fxregs_state from being output to the kernel XSAVES area. Thus the
correct mask corresponding to XCR0 was not present in the core file
for GDB to interrogate, resulting in the following behavior:
[kev@f32-1 gdb]$ ./gdb -q testsuite/outputs/gdb.base/corefile/corefile testsuite/outputs/gdb.base/corefile/corefile.core
Reading symbols from testsuite/outputs/gdb.base/corefile/corefile...
[New LWP 232880]
warning: Unexpected size of section `.reg-xstate/232880' in core file.
With the typo fixed, the test works again as expected.
