2006-05-05[IA64] strcpy returns NULL pointer and not destination pointerChen, Kenneth W
Bob Picco noted that 6edfba1b33c701108717f4e036320fc39abe1912 dropped the -ffreestanding compiler flag from the top level Makefile, which allows the compiler to substitute memcpy() in places where strcpy() is used with a known size source string. But the ia64 memcpy() returns 0 for success, and "bytes copied" for failure. Fix to return the address of the destination string (like stdlibc version, and other architectures). There are no places where ia64 specific code makes use of the non-standard return value. Signed-off-by: Ken Chen <kenneth.w.chen@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2005-09-07[IA64] make exception handler in copy_user more robustChen, Kenneth W
The exception handler in copy user always expects fault occurs only on user space address and the fall back recovery code is written with that very assumption in mind. Recent source code inspection revealed that while it worked splendid and to the expectation under normal circumstances, It broke down under unexpected condition where some address calculation might go outside the legal address range the original copy_user was called for. This patch is to make copy_user exception handler more robust and to prevent potential memory corruption.

2005-04-25[IA64] __copy_user breaks on unaligned srcKeith Owens
memcpy_mck.S::__copy_user breaks in the prefetch code under these conditions :- * src is unaligned and * dst is near the end of a page and * the page after dst is unmapped. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
