The kernel version of Linux statfs64 is actually supposed to take

3 arguments, but we had forgotten the second argument. Also make the Linux statfs64 struct depend on the architecture because it has an extra 4 bytes padding on amd64 compared to i386. The three argument fix is from David Taylor, the struct statfs64 stuff is my fault. With this patch I can install i386 Linux matlab on an amd64 machine.

Fix a couple of issues with the stack limit for 32-bit processes on 64-bit

2007-07-12T18:01:31Z

kernels exposed by the recent fixes to resource limits for 32-bit processes on 64-bit kernels: - Let ABIs expose their maximum stack size via a new pointer in sysentvec and use that in preference to maxssiz during exec() rather than always using maxssiz for all processses. - Apply the ABI's limit fixup to the previous stack size when adjusting RLIMIT_STACK to determine if the existing mapping for the stack needs to be grown or shrunk (as well as how much it should be grown or shrunk).

Don't add the 'pad' argument to the mmap/truncate/etc syscalls.

Commit 14/14 of sched_lock decomposition.

2007-06-05T00:00:57Z

- Use thread_lock() rather than sched_lock for per-thread scheduling sychronization. - Use the per-process spinlock rather than the sched_lock for per-process scheduling synchronization.

Move futex support code from /support.s into linux compat directory.

Implement all futex atomic operations in assembler to not depend on the fuword() that does not allow to distinguish between -1 and failure return. Correctly return 0 from atomic operations on success. In collaboration with: rdivacky Tested by: Scot Hetzel , Milos Vyletel Sponsored by: Google SoC 2007

Rework the support for ABIs to override resource limits (used by 32-bit

processes under 64-bit kernels). Previously, each 32-bit process overwrote its resource limits at exec() time. The problem with this approach is that the new limits affect all child processes of the 32-bit process, including if the child process forks and execs a 64-bit process. To fix this, don't ovewrite the resource limits during exec(). Instead, sv_fixlimits() is now replaced with a different function sv_fixlimit() which asks the ABI to sanitize a single resource limit. We then use this when querying and setting resource limits. Thus, if a 32-bit process sets a limit, then that new limit will be inherited by future children. However, if the 32-bit process doesn't change a limit, then a future 64-bit child will see the "full" 64-bit limit rather than the 32-bit limit. MFC is tentative since it will break the ABI of old linux.ko modules (no other modules are affected). MFC after: 1 week
