riscv: Fix TASK_SIZE on 64-bit NOMMU
[ Upstream commit 6065e736f82c817c9a597a31ee67f0ce4628e948 ]
On NOMMU, userspace memory can come from anywhere in physical RAM. The
current definition of TASK_SIZE is wrong if any RAM exists above 4G,
causing spurious failures in the userspace access routines.
Fixes: 6bd33e1ece52 ("riscv: add nommu support")
Fixes: c3f896dcf1e4 ("mm: switch the test_vmalloc module to use __vmalloc_node")
