Before the change osReserveHeapMemory() attempted to allocate chunks of memory via osTryReserveHeapMemory() not multiple of MBLOCK_SIZE in the following fallback code: ``` if (at == NULL) { *len -= *len / 8; ``` and caused assertion failure: ``` $ make fulltest TEST=T11607 WAY=threaded1 T11607: internal error: ASSERTION FAILED: file rts/posix/OSMem.c, line 457 (GHC version 8.7.20180716 for riscv64_unknown_linux) ``` The change applies alignment mask before each MBLOCK allocation attempt and fixes WAY=threaded1 test failures on qemu-riscv64.
