Implement ioremap_prot() to allow mapping IO memory with variable protection via TLB. Implementing this allows the /dev/mem driver to use its generic access() VMA callback, which in turn allows ptrace to examine data in memory mapped regions mapped via /dev/mem, such as Arc DCCM. The end result is that it is possible to examine values of variables placed into DCCM in user space programs via GDB.

1. ./genfilelist.pl arch/arc/include/asm/ 2. Create arch/arc/include/uapi/asm/Kbuild as follows +# UAPI Header export list +include include/uapi/asm-generic/Kbuild.asm 3. ./disintegrate-one.pl arch/arc/include/{,uapi/}asm/<above-list> 4. Edit arch/arc/include/asm/Kbuild to remove ref to asm-generic/Kbuild.asm - To work around empty uapi/asm/setup.h added a placholder comment. - Also a manual #ifdef __ASSEMBLY__ for a late ptrace change Signed-off-by: NVineet Gupta <vgupta@synopsys.com> Cc: David Howells <dhowells@redhat.com>
