alpha: unbreak OSF/1 (a.out) binaries
commit 2444e56b0c08e6f3e3877583841a1213e3263d98 upstream
OSF/1 brk(2) was broken by following one-liner in sys_brk()
(commit 4cc6028d4040f95cdb590a87db478b42b8be0508):
- if (brk < mm->end_code)
+ if (brk < mm->start_brk)
goto out;
The problem is that osf_set_program_attributes()
does update mm->end_code, but not mm->start_brk,
which still contains inappropriate value left from
binary loader, so brk() always fails.
