Samuel HollandandGreg Kroah-Hartman 4201b8c8f2 riscv: Fix TASK_SIZE on 64-bit NOMMU ...

[ Upstream commit 6065e736f8 ]

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: 6bd33e1ece ("riscv: add nommu support")
Fixes: c3f896dcf1 ("mm: switch the test_vmalloc module to use __vmalloc_node")
