* | | | [PATCH] Kprobes: rearrange preempt_disable/enable() callsAnanth N Mavinakayanahalli2005-11-075-56/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following set of patches are aimed at improving kprobes scalability. We currently serialize kprobe registration, unregistration and handler execution using a single spinlock - kprobe_lock. With these changes, kprobe handlers can run without any locks held. It also allows for simultaneous kprobe handler executions on different processors as we now track kprobe execution on a per processor basis. It is now necessary that the handlers be re-entrant since handlers can run concurrently on multiple processors. All changes have been tested on i386, ia64, ppc64 and x86_64, while sparc64 has been compile tested only. The patches can be viewed as 3 logical chunks: patch 1: Reorder preempt_(dis/en)able calls patches 2-7: Introduce per_cpu data areas to track kprobe execution patches 8-9: Use RCU to synchronize kprobe (un)registration and handler execution. Thanks to Maneesh Soni, James Keniston and Anil Keshavamurthy for their review and suggestions. Thanks again to Anil, Hien Nguyen and Kevin Stafford for testing the patches. This patch: Reorder preempt_disable/enable() calls in arch kprobes files in preparation to introduce locking changes. No functional changes introduced by this patch.

* | | | [PATCH] consolidate sys_ptrace()Christoph Hellwig2005-11-0719-818/+62

This patch moves it to kernel/ptrace.c and leaves the arch-specific code as arch_ptrace. Some architectures have a too different ptrace so we have to exclude them. They continue to keep their implementations. For sh64 I had to add a sh64_ptrace wrapper because it does some initialization on the first call. For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

It does not work together with the system call speedup that makes the complete system call path enabled for interrupts. To make pagex and the syscall speedup code work together we would have to add code to the program check handler to do a critical section cleanup like the asynchronous interrupt code. This would make program checks slower. Not what we want. Newer versions of z/VM have the improved pfault pseudo page fault interface. This replaces the old pagex interface and does not have the problem. So its better to just rip out the pagex code.

Network code uses htons() to convert it. So UML's method to access these fields is wrong for bigendians (e.g. s390) I replaced bytewise copying by memcpy(), maybe even that might be removed, if ifa->ifa_address/mask may be used immediately.

* | | | [PATCH] uml: fix syscall stubsPaolo 'Blaisorblade' Giarrusso2005-11-072-33/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jeff Dike noted that the assembly code for syscall stubs is misassembled with GCC 3.2.3: the values copied in registers weren't preserved between one asm() and the following one. So I fixed the thing by rewriting the __asm__ constraints more like unistd.h ones. Note: in syscall6 case I had to add one more instruction (i.e. moving arg6 in eax and shuffling things around) - it's needed for the function to be valid in general (we can't load the value from the stack, relative to ebp, because we change it), but could be avoided since we actually use a constant as param 6. The only fix would be to turn stub_syscall6 to a macro and use a "i" constraint for arg6 (i.e., specify it's a constant value).

As a result, BIOS ends up bombarded with interrupts early on boot. The BIOS does not expect it since following a "normal" hardware cpu reset, all APIC LVT registers have the Mask bit (16) set and can't generate interrupts. For example, the version of Phoenix BIOS used by VMware enables interrupts for the first time before masking/clearing APIC LVT. The APIC Timer LVT register is still set up for a timer interrupt delivery with a high vector from the previous Linux incarnation (0xef in our case). The BIOS has not fully initialized its IDT at this point and the real mode gate for 0xef remains all zeros. Vector 0xef dispatches BIOS to address 0:0, BIOS takes a #GP and eventually hangs. machine_shutdown() does attempt to shut down APIC before jumping to BIOS, but it is ineffective" Signed-off-by: Zwane Mwaikambo <zwane@arm.linux.org.uk> Cc: "Seth, Rohit" <rohit.seth@intel.com> Cc: Zachary Amsden <zach@vmware.com> Cc: "Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SH7705 in extended cache mode has some left-over VALID_PAGE() cruft that it checks when doing lazy dcache write-back. This has been gone for some time (the last bits were in the discontig code, which should now also be gone -- this also fixes up a build error in the non-discontig case). pfn_valid() gives the desired behaviour, so we switch to that.

If we bump up the P1 offset, it's possible to hit a shadowed region of memory where we suddenly become magically contiguous. As people have been using this shadowed region workaround for quite some time (and without any adverse effects), it's time to drop the left over discontig bits that no longer have any practical use (it was always very much hp690-centric to begin with).
