[Jin Zhengxiong-R64188] Need to set TASK_UNMAPPED_BASE somewhere below 0x80000000
to not break runtime linker. When ld.so is invoked explicitly
(i.e., /lib/ld.so.1 ./myprog), it needs to be loaded below 0x80000000,
otherwise it will overwrite itself with the program it tries to load.
The comments come from codesourcery and we have set it to 0x60000000
in the latest BSP.
Ok, thanks. I will change that in the patches to 0x60000000 then.
Regards
Greg
