Pull char/misc driver fixes from Greg KH: "Here are some binder, habanalabs, and vboxguest driver fixes for 5.1-rc3. The Binder fixes resolve some reported issues found by testing, first by the selinux developers, and then earlier today by syzbot. The habanalabs fixes are all minor, resolving a number of tiny things. The vboxguest patches are a bit larger. They resolve the fact that virtual box decided to change their api in their latest release in a way that broke the existing kernel code, despite saying that they were never going to do that. So this is a bit of a "new feature", but is good to get merged so that 5.1 will work with the latest release. The changes are not large and of course virtual box "swears" they will not break this again, but no one is holding their breath here. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: virt: vbox: Implement passing requestor info to the host for VirtualBox 6.0.x binder: fix race between munmap() and direct reclaim binder: fix BUG_ON found by selinux-testsuite habanalabs: cast to expected type habanalabs: prevent host crash during suspend/resume habanalabs: perform accounting for active CS habanalabs: fix mapping with page size bigger than 4KB habanalabs: complete user context cleanup before hard reset habanalabs: fix bug when mapping very large memory area habanalabs: fix MMU number of pages calculation
