vxge_os_dma_malloc() and vxge_os_dma_malloc_async() are both called from
callchains which use GFP_KERNEL allocations unconditionally or have other
requirements to be called from fully preemptible task context..
vxge_os_dma_malloc():
1) __vxge_hw_blockpool_create() <- GFP_KERNEL
2) __vxge_hw_mempool_grow() <- vzalloc()
__vxge_hw_blockpool_malloc()
vxge_os_dma_malloc_async():
1 __vxge_hw_mempool_grow() <- vzalloc()
__vxge_hw_blockpool_malloc()
__vxge_hw_blockpool_blocks_add()
2) vxge_hw_vpath_open() <- vzalloc()
__vxge_hw_blockpool_block_allocate()
That means neither of these functions needs a conditional allocation mode.
Remove the in_interrupt() conditional and use GFP_KERNEL.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
