Can you give it a try with following patch in OpenSBI & Kernel ?

Linux kernel:
http://lists.infradead.org/pipermail/linux-riscv/2019-August/005889.html

OpenSBI:
http://lists.infradead.org/pipermail/opensbi/2019-August/000386.html

In my testing, I no longer the stress-ng error or glibc local install
issue if I use following command.

sudo make -j8 localedata/install-locale-files
DESTDIR=/home/atish/glibc/build/install


I still see segmentation fault if I use a archieve locale install
command.

sudo make -j8 localedata/install-locales
DESTDIR=/home/atish/glibc/build/install

But the error dump doesn't contain remap() error. Just a segmentation
fault which may be due to userspace or just different version of old
tlbflush problem.


Regards,
Atish
