-    virt: vbox: Use __get_free_pages instead of kmalloc for DMA32 memory
-
-    It is not possible to get DMA32 zone memory through kmalloc, causing
-    the vboxguest driver to malfunction due to getting memory above
-    4G which the PCI device cannot handle.
-
-    This commit changes the kmalloc calls where the 4G limit matters to
-    using __get_free_pages() fixing vboxguest not working on x86_64 guests
-    with more then 4G RAM.

-    virt: vbox: Add vbg_req_free() helper function
-
-    This is a preparation patch for fixing issues on x86_64 virtual-machines
-    with more then 4G of RAM, atm we pass __GFP_DMA32 to kmalloc, but kmalloc
-    does not honor that, so we need to switch to get_pages, which means we
-    will not be able to use kfree to free memory allocated with vbg_alloc_req.
-
-    While at it also remove a comment on a vbg_alloc_req call which talks
-    about Windows (inherited from the vbox upstream cross-platform code).
