Mesa has been issuing a single bind operation per ioctl since xe.ko changed to GPUVA due xe.ko bug #746. If I change Mesa to try again to issue every single bind operation it can in the same ioctl, it hits the MAX_BINDS assertion when running Vulkan conformance tests. Test dEQP-VK.sparse_resources.transfer_queue.3d.rgba32i.1024_128_8 issues 960 bind operations in a single ioctl, it's the most I could find in the conformance suite. I don't see a reason to keep the MAX_BINDS restriction: it doesn't seem to be preventing any specific issue. If the number is too big for the memory allocations, then those will fail. Nothing related to num_binds seems to be using the stack. Let's just get rid of it.

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.
