Raw Normal View History

Linux-2.6.12-rc2 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!

[AUDIT] Update UML audit-syscall-{entry,exit} calls to new prototypes This patch is for -mm only. It should probably be included in git-audit, and should be forwarded to Linus iff git-audit is. It updates the audit-syscall-{entry,exit} calls to current -mm.

[PATCH] uml: implement {get,set}_thread_area for i386 Implement sys_[gs]et_thread_area and the corresponding ptrace operations for UML. This is the main chunk, additional parts follow. This implementation is now well tested and has run reliably for some time, and we've understood all the previously existing problems. Their implementation saves the new GDT content and then forwards the call to the host when appropriate, i.e. immediately when the target process is running or on context switch otherwise (i.e. on fork and on ptrace() calls). In SKAS mode, we must switch registers on each context switch (because SKAS does not switches tls_array together with current->mm). Also, added get_cpu() locking; this has been done for SKAS mode, since TT does not need it (it does not use smp_processor_id()).

[PATCH] uml: add profile_pc for i386 Cope with a conditional i386 definition, which is wrong for UML. Before we just used that one, but it wasn't defined for CONFIG_SMP, so in that case we got link errors.
