test_find_delalloc() allocates 256 MB worth of pages. That's all of the
RAM that my MIPS emulator has, so it ends up panicking after it OOM
kills everything. We don't actually need to use that much for this test.

I'm not sure we should limit it that way as more bytes can give it more
stress. Can we do it somehow dynamically ? Like start with 256M and fall
back to the numbers you've used.

Or maybe start from the low bound and allocate until it fails with first
ENOMEM.

I figured out how to get qemu to do highmem on MIPS, so we can drop this
patch. It's reasonable to assume that the sanity tests are running on a
machine with a decent amount of memory.
