* uml: ptrace floating point fixesJeff Dike2007-10-161-0/+6
| | | | | | | | | | | | | | | | Handle floating point state better in ptrace. The code now correctly distinguishes between PTRACE_[GS]ETFPREGS and PTRACE_[GS]ETFPXREGS. The FPX requests get handed off to arch-specific code because that's not generic. get_fpregs, set_fpregs, set_fpregs, and set_fpxregs needed real implementations. Something here exposed a missing include in asm/page.h, which needed linux/types.h in order to get gfp_t, so that's fixed here.

| | | | | | | | | | | | | | | Formatting changes in the files which have been changed in the course of folding foo_skas functions into their callers. These include: copyright updates header file trimming style fixes adding severity to printks These changes should be entirely non-functional.

* uml: remove code made redundant by CHOOSE_MODE removalJeff Dike2007-10-161-17/+0
| | | | | | | | | | | | | | | | | | | | | | This patch makes a number of simplifications enabled by the removal of CHOOSE_MODE. There were lots of functions that looked like int foo(args){ foo_skas(args); } The bodies of foo_skas are now folded into foo, and their declarations (and sometimes entire header files) are deleted. In addition, the union uml_pt_regs, which was a union between the tt and skas register formats, is now a struct, with the tt-mode arm of the union being removed. It turns out that usr2_handler was unused, so it is gone.

* uml: throw out CHOOSE_MODEJeff Dike2007-10-161-10/+2
| | | | | | | | | | | | | | | | | The next stage after removing code which depends on CONFIG_MODE_TT is removing the CHOOSE_MODE abstraction, which provided both compile-time and run-time branching to either tt-mode or skas-mode code. This patch removes choose-mode.h and all inclusions of it, and replaces all CHOOSE_MODE invocations with the skas branch. This leaves a number of trivial functions which will be dealt with in a later patch. There are some changes in the uaccess and tls support which go somewhat beyond this and eliminate some of the now-redundant functions.

* [PATCH] uml: fix "extern-vs-static" proto conflict in TLS codePaolo 'Blaisorblade' Giarrusso2006-04-111-0/+3
| | | | | | | | | | Move the prototype from arch-generic to arch-specific includes because on x86_64 these functions are two static inlines.

* [PATCH] uml: implement {get,set}_thread_area for i386Paolo 'Blaisorblade' Giarrusso2006-03-311-11/+30
| | | | | | | | | | | | | | | | | | | | | | 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 i386Paolo 'Blaisorblade' Giarrusso2005-06-251-0/+4
| | | | | | | | | | | 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.

* [AUDIT] Update UML audit-syscall-{entry,exit} calls to new prototypesJeff Dike2005-05-031-0/+2
| | | | | | | | | | | | 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.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+46
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!
