2005-09-13[ARM] 2896/1: Add sys_ipc_wrapper to pass 'fifth' argument on stackGeorge G. Davis
Patch from George G. Davis As pointed out be Matthew Klahn <MKLAHN@motorola.com>, some sys_ipc() call options require six args, e.g. SEMTIMEDOP. This patch adds an ARM sys_ipc_wrapper to save the sys_ipc() 'fifth' arg on the stack. Signed-off-by: George G.

2005-09-09[ARM] sys_mbind needs wrappingRussell King
sys_mbind is a 6-arg syscall, hence needs wrapping to save the sixth argument. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-09-01[ARM] 2865/2: fix fadvise64_64 syscall argument passingNicolas Pitre
Patch from Nicolas Pitre The prototype for sys_fadvise64_64() is: long sys_fadvise64_64(int fd, loff_t offset, loff_t len, int advice) The argument list is therefore as follows on legacy ABI: fd: type int (r0) offset: type long long (r1-r2) len: type long long (r3-sp[0]) advice: type int (sp[4]) With EABI this becomes: fd: type int (r0) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) advice: type int (sp[8]) Not only do we have ABI differences here, but the EABI version requires one additional word on the syscall stack. To avoid the ABI mismatch and the extra stack space required with EABI this syscall is now defined with a different argument ordering on ARM as follows: long sys_arm_fadvise64_64(int fd, int advice, loff_t offset, loff_t len) This gives us the following ABI independent argument distribution: fd: type int (r0) advice: type int (r1) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) Now, since the syscall entry code takes care of 5 registers only by default including the store of r4 to the stack, we need a wrapper to store r5 to the stack as well. Because that wrapper was missing and was always required this means that sys_fadvise64_64 never worked on ARM and therefore we can safely reuse its syscall number for our new sys_arm_fadvise64_64 interface.

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!
