ARC700 4.10 supports configurable MMU page sizes:
ARC Linux supports: 8k (default), 4k and 16k

Following are the steps to add non-default page size support to kernel/tools.

--------------------------------------------------------------------------
(1) kernel
--------------------------------------------------------------------------
Edit arch/arc/include/asm/page.h

-#define PAGE_SHIFT     13	//8k
+#define PAGE_SHIFT     14	//16k
+#define PAGE_SHIFT     12	//4k

--------------------------------------------------------------------------
(2) Tools
--------------------------------------------------------------------------
The system libs (uClibc/math/pthread etc) as well as the exported headers
need to be rebuilt with modified page size.

(2a) Since all the tools need not be rebuilt, clone an existing 2.4 based
installed GNU tool-chain

cp-rfd GNUINST GNUINST_stock8k

(2b) As of Sept 1st 2011- You'll need to hack the installed linker scripts
     for both shared libs as well as executables.
     The same scripts are good for 4k/8k/16k.

GNUINST/uclibc/arc-linux-uclibc/lib/ldscripts/arclinux.x
GNUINST/uclibc/arc-linux-uclibc/lib/ldscripts/arclinux.xs

-   . = ALIGN(0x2000) + (. & (0x2000 - 1));
+	. = DATA_SEGMENT_ALIGN (0x4000, 0x2000);

(2c) Edit GNUSRC/2.4/uClibc-0.9.29/libc/sysdeps/linux/arc/bits/uClibc_page.h

-#define PAGE_SHIFT     13	//8k
+#define PAGE_SHIFT     14	//16k
+#define PAGE_SHIFT     12	//4k

(2d) Rebuild uClibc (which rebuilds other system libs as well)
cd GNUSRC/2.4/uClibc-0.9.29
make CROSS_COMPILE=arc-linux-uclibc-gcc && make install

This will install the specific 4k or 16k variant of libs/headers in GNUINST

(2e) Modify you path to point to the 8k based toolcian (GNUINST_stock8k) or
the modified page size based one (GNUINST)
