It is incorrect to pass it in as an output constraint since the asm will never update the pointer. Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-02-11perf_counters: allow users to count user, kernel and/or hypervisor eventsPaul Mackerras
Impact: new perf_counter feature This extends the perf_counter_hw_event struct with bits that specify that events in user, kernel and/or hypervisor mode should not be counted (i.e. should be excluded), and adds code to program the PMU mode selection bits accordingly on x86 and powerpc. For software counters, we don't currently have the infrastructure to distinguish which mode an event occurs in, so we currently fail the counter initialization if the setting of the hw_event.exclude_* bits would require us to distinguish. Context switches and CPU migrations are currently considered to occur in kernel mode. On x86, this changes the previous policy that only root can count kernel events. Now non-root users can count kernel events or exclude them. Non-root users still can't use NMI events, though. On x86 we don't appear to have any way to control whether hypervisor events are counted or not, so hw_event.exclude_hv is ignored. On powerpc, the selection of whether to count events in user, kernel and/or hypervisor mode is PMU-wide, not per-counter, so this adds a check that the hw_event.exclude_* settings are the same as other events on the PMU. Counters being added to a group have to have the same settings as the other hardware counters in the group. Counters and groups can only be enabled in hw_perf_group_sched_in or power_perf_enable if they have the same settings as any other counters already on the PMU. If we are not running on a hypervisor, the exclude_hv setting is ignored (by forcing it to 0) since we can't ever get any hypervisor events. Signed-off-by: Paul Mackerras <paulus@samba.org>

2009-02-10tracing, x86: fix fixup section to return to original codeSteven Rostedt
Impact: fix to prevent a kernel crash on fault If for some reason the pointer to the parent function on the stack takes a fault, the fix up code will not return back to the original faulting code. This can lead to unpredictable results and perhaps even a kernel panic. A fault should not happen, but if it does, we should simply disable the tracer, warn, and continue running the kernel. It should not lead to a kernel crash. Signed-off-by: Steven Rostedt <srostedt@redhat.com>

2009-02-10powerpc/pci: mmap anonymous memory when legacy_mem doesn't existBenjamin Herrenschmidt
The new legacy_mem file in sysfs is causing problems with X on machines that don't support legacy memory access. The way I initially implemented it, we would fail with -ENXIO when trying to mmap it, thus exposing to X that we do support the API but there is no legacy memory. Unfortunately, X poor error handling is causing it to fail to start when it gets this error. This implements a workaround hack that instead maps anonymous memory instead (using shmem if VM_SHARED is set, just like /dev/zero does).

2009-02-10x86: fix math_emu register frame accessTejun Heo
do_device_not_available() is the handler for #NM and it declares that it takes a unsigned long and calls math_emu(), which takes a long argument and surprisingly expects the stack frame starting at the zero argument would match struct math_emu_info, which isn't true regardless of configuration in the current code. This patch makes do_device_not_available() take struct pt_regs like other exception handlers and initialize struct math_emu_info with pointer to it and pass pointer to the math_emu_info to math_emulate() like normal C functions do. This way, unless gcc makes a copy of struct pt_regs in do_device_not_available(), the register frame is correctly accessed regardless of kernel configuration or compiler used. This doesn't fix all math_emu problems but it at least gets it somewhat working. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-02-09x86, vmi: put a missing paravirt_release_pmd in pgd_dtorAlok Kataria
Commit 6194ba6ff6ccf8d5c54c857600843c67aa82c407 ("x86: don't special-case pmd allocations as much") made changes to the way we handle pmd allocations, and while doing that it dropped a call to paravirt_release_pd on the pgd page from the pgd_dtor code path. As a result of this missing release, the hypervisor is now unaware of the pgd page being freed, and as a result it ends up tracking this page as a page table page. After this the guest may start using the same page for other purposes, and depending on what use the page is put to, it may result in various performance and/or functional issues ( hangs, reboots). Since this release is only required for VMI, I now release the pgd page from the (vmi)_pgd_free hook.

2009-02-08sparc64: Fix probe_kernel_{read,write}().David S. Miller
This is based upon a report from Chris Torek and his initial patch. From Chris's report: -------------------- This came up in testing kgdb, using the built-in tests -- turn on CONFIG_KGDB_TESTS, then echo V1 > /sys/module/kgdbts/parameters/kgdbts -- but it would affect using kgdb if you were debugging and looking at bad pointers. -------------------- When we get a copy_{from,to}_user() request and the %asi is set to something other than ASI_AIUS (which is userspace) then we branch off to a routine called memcpy_user_stub(). It just does a straight memcpy since we are copying from kernel to kernel in this case. The logic was that since source and destination are both kernel pointers we don't need to have exception checks. But for what probe_kernel_{read,write}() is trying to do, we have to have the checks, otherwise things like kgdb bad kernel pointer accesses don't do the right thing. Signed-off-by: David S.

2009-02-06x86-64: fix int $0x80 -ENOSYS returnRoland McGrath
One of my past fixes to this code introduced a different new bug. When using 32-bit "int $0x80" entry for a bogus syscall number, the return value is not correctly set to -ENOSYS. This only happens when neither syscall-audit nor syscall tracing is enabled (i.e., never seen if auditd ever started). Test program: /* gcc -o int80-badsys -m32 -g int80-badsys.c Run on x86-64 kernel. Note to reproduce the bug you need auditd never to have started. */ #include <errno.h> #include <stdio.h> int main (void) { long res; asm ("int $0x80" : "=a" (res) : "0" (99999)); printf ("bad syscall returns %ld\n", res); return res != -ENOSYS; } The fix makes the int $0x80 path match the sysenter and syscall paths.
