I still don't think this is correct.
I have done these steps
make mrproper
make ARCH=microblaze headers_install INSTALL_HDR_PATH=/tmp/ && move
Applied 1/3
make ARCH=microblaze headers_install INSTALL_HDR_PATH=/tmp/ && move
Applied 2/3
make ARCH=microblaze headers_install INSTALL_HDR_PATH=/tmp/ && move
Applied 3/3
make ARCH=microblaze headers_install INSTALL_HDR_PATH=/tmp/ && move
And compare all these versions. Till 2/3 all is fine but when 3/3 is
applied
include/asm/unistd.h contains
#include <asm/unistd_32.h>
Then include/asm/unistd_32.h contains
#include <asm-generic/unistd_32.h>
which is different syscalls table.
I didn't play with it for a long time but removing generic unistd_32.h
is fixing it. Please take a look.
