* x86: print which shared library/executable faulted in segfault etc. messages v3Andi Kleen2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | They now look like: hal-resmgr[13791]: segfault at 3c rip 2b9c8caec182 rsp 7fff1e825d30 error 4 in libacl.so.1.1.0[2b9c8caea000+6000] This makes it easier to pinpoint bugs to specific libraries. And printing the offset into a mapping also always allows to find the correct fault point in a library even with randomized mappings. Previously there was no way to actually find the correct code address inside the randomized mapping. Relies on earlier patch to shorten the printk formats. They are often now longer than 80 characters, but I think that's worth it.

* x86: optimize lock prefix switching to run less frequentlyAndi Kleen2008-01-30
| | | | | | | | | | | | | | | | | | | | | | On VMs implemented using JITs that cache translated code changing the lock prefixes is a quite costly operation that forces the JIT to throw away and retranslate a lot of code. Previously a SMP kernel would rewrite the locks once for each CPU which is quite unnecessary. This patch changes the code to never switch at boot in the normal case (SMP kernel booting with >1 CPU) or only once for SMP kernel on UP. This makes a significant difference in boot up performance on AMD SimNow! Also I expect it to be a little faster on native systems too because a smp switch does a lot of text_poke()s which each synchronize the pipeline. v1->v2: Rename max_cpus v1->v2: Fix off by one in UP check (Thomas Gleixner) Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: add ENDPROC() markersJohn Reiser2008-01-30
| | | | | | | | | | | The ENDPROCs() were not used everywhere. Some code used just END() instead, while other code used nothing. um/sys-i386/checksum.S didn't #include <linux/linkage.h> . I also got confused because gcc puts the .type near the ENTRY, while ENDPROC puts it on the opposite end.

* x86: kprobes: add kprobes smoke tests that run on bootAnanth N Mavinakayanahalli2008-01-30
| | | | | | | | | | | | | | | | | | | | | Here is a quick and naive smoke test for kprobes. This is intended to just verify if some unrelated change broke the *probes subsystem. It is self contained, architecture agnostic and isn't of any great use by itself. This needs to be built in the kernel and runs a basic set of tests to verify if kprobes, jprobes and kretprobes run fine on the kernel. In case of an error, it'll print out a message with a "BUG" prefix. This is a start; we intend to add more tests to this bucket over time. Thanks to Jim Keniston and Masami Hiramatsu for comments and suggestions. Tested on x86 (32/64) and powerpc.

* x86: user_regset user-copy helpersRoland McGrath2008-01-30
| | | | | | | | | | | | | This defines two new inlines in linux/regset.h, for use in arch_ptrace implementations and the like. These provide simplified wrappers for using the user_regset interfaces to copy thread regset data into the caller's user-space memory. The inlines are trivial, but make the common uses in places such as ptrace implementation much more concise, easier to read, and less prone to code-copying errors.

* x86: user_regset helpersRoland McGrath2008-01-30
| | | | | | | | | | | | | | | | | | | | | This adds some inlines to linux/regset.h intended for arch code to use in its user_regset get and set functions. These make it pretty easy to deal with the interface's optional kernel-space or user-space pointers and its generalized access to a part of the register data at a time. In simple cases where the internal data structure matches the exported layout (core dump format), a get function can be nothing but a call to user_regset_copyout, and a set function a call to user_regset_copyin. In other cases the exported layout is usually made up of a few pieces each stored contiguously in a different internal data structure. These helpers make it straightforward to write a get or set function by processing each contiguous chunk of the data in order. The start_pos and end_pos arguments are always constants, so these inlines collapse to a small amount of code.

* x86: user_regset headerRoland McGrath2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new header <linux/regset.h> defines the types struct user_regset and struct user_regset_view, with some associated declarations. This new set of interfaces will become the standard way for arch code to expose user-mode machine-specific state. A single set of entry points into arch code can do all the low-level work in one place to fill the needs of core dumps, ptrace, and any other user-mode debugging facilities that might come along in the future. For existing arch code to adapt to the user_regset interfaces, each arch can work from the code it already has to support core files and ptrace. The formats you want for user_regset are the core file formats. The only wrinkle in adapting old ptrace implementation code as user_regset get and set functions is that these functions can be called on current as well as on another task_struct that is stopped and switched out as for ptrace. For some kinds of machine state, you may have to load it directly from CPU registers or otherwise differently for current than for another thread. (Your core dump support already handles this in elf_core_copy_regs for current and elf_core_copy_task_regs for other tasks, so just check there.) The set function should also be made to work on current in case that entails some special cases, though this was never required before for ptrace. Adding this flexibility covers the arch needs to open the door to more sophisticated new debugging facilities that don't always need to context-switch to do every little thing. The copyin/copyout helper functions (in a later patch) relieve the arch code of most of the cumbersome details of the flexible get/set interfaces.

* spinlock: lockbreak cleanupNick Piggin2008-01-30
| | | | | | | | | | | | | | | | | | | | The break_lock data structure and code for spinlocks is quite nasty. Not only does it double the size of a spinlock but it changes locking to a potentially less optimal trylock. Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a __raw_spin_is_contended that uses the lock data itself to determine whether there are waiters on the lock, to be used if CONFIG_GENERIC_LOCKBREAK is not set. Rename need_lockbreak to spin_needbreak, make it use spin_is_contended to decouple it from the spinlock implementation, and make it typesafe (rwlocks do not have any need_lockbreak sites -- why do they even get bloated up with that break_lock then?).

* x86: remove extern declarations for code, data, bss resourcesBernhard Walle2008-01-30
| | | | | | | | | | | | | | | | | | | | | This patch removes the extern struct resource declarations for data_resource, code_resource and bss_resource on x86 and declares that three structures as static as done on other architectures like IA64. On i386, these structures are moved to setup_32.c (from e820_32.c) because that's code that is not specific to e820 and also required on EFI systems. That makes the "extern" reference superfluous. On x86_64, data_resource, code_resource and bss_resource are passed to e820_reserve_resources() as arguments just as done on i386 and IA64. That also avoids the "extern" reference and it's possible to make it static.

* NLM/NFS: Use cached nlm_host when calling nlmclnt_proc()Chuck Lever2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that each NFS mount point caches its own nlm_host structure, it can be passed to nlmclnt_proc() for each lock request. By pinning an nlm_host for each mount point, we trade the overhead of looking up or creating a fresh nlm_host struct during every NLM procedure call for a little extra memory. We also restrict the nlmclnt_proc symbol to limit the use of this call to in-tree modules. Note that nlm_lookup_host() (just removed from the client's per-request NLM processing) could also trigger an nlm_host garbage collection. Now client-side nlm_host garbage collection occurs only during NFS mount processing. Since the NFS client now holds a reference on these nlm_host structures, they wouldn't have been affected by garbage collection anyway. Given that nlm_lookup_host() reorders the global nlm_host chain after every successful lookup, and that a garbage collection could be triggered during the call, we've removed a significant amount of per-NLM-request CPU processing overhead. Sidebar: there are only a few remaining references to the internals of NFS inodes in the client-side NLM code. The only references I found are related to extracting or comparing the inode's file handle via NFS_FH(). One is in nlmclnt_grant(); the other is in nlmclnt_setlockargs().

The new architecture pins an nlm_host structure to each NFS client superblock that has the "lock" mount option set. The NFS client passes in the pinned nlm_host structure during each call to nlmclnt_proc(). NFS client unmount processing "puts" the nlm_host so it can be garbage- collected later. This patch introduces externally callable NLM functions that handle mount-time nlm_host set up and tear-down.
