The newly added event_lock spinlock in the input core disallows sleeping and therefore using mutexes in event handlers. Convert force-feedback core to rely on event_lock instead of mutex to protect slots allocated for fore-feedback effects. The original mutex is still used to serialize uploading and erasing of effects. Reported-by: Anssi Hannula <anssi.hannula@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

When I update kernel 2.6.25 from 2.6.24, gdb does not work. On 2.6.25, ptrace(PTRACE_GETFPXREGS, ...) returns ENODEV. But 2.6.24 kernel's ptrace() returns EIO. It is issue of compatibility. I attached test program as pt.c and patch for fix it. #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <signal.h> #include <errno.h> #include <sys/ptrace.h> #include <sys/types.h> struct user_fxsr_struct { unsigned short cwd; unsigned short swd; unsigned short twd; unsigned short fop; long fip; long fcs; long foo; long fos; long mxcsr; long reserved; long st_space[32]; /* 8*16 bytes for each FP-reg = 128 bytes */ long xmm_space[32]; /* 8*16 bytes for each XMM-reg = 128 bytes */ long padding[56]; }; int main(void) { pid_t pid; pid = fork(); switch(pid){ case -1:/* error */ break; case 0:/* child */ child(); break; default: parent(pid); break; } return 0; } int child(void) { ptrace(PTRACE_TRACEME); kill(getpid(), SIGSTOP); sleep(10); return 0; } int parent(pid_t pid) { int ret; struct user_fxsr_struct fpxregs; ret = ptrace(PTRACE_GETFPXREGS, pid, 0, &fpxregs); if(ret < 0){ printf("%d: %s.\n", errno, strerror(errno)); } kill(pid, SIGCONT); wait(pid); return 0; } /* in the kerel, at kernel/i387.c get_fpxregs() */ Signed-off-by: Ingo Molnar <mingo@elte.hu>

Vegard Nossum reported crashes during cpu hotplug tests: http://marc.info/?l=linux-kernel&m=121413950227884&w=4 In function _cpu_up, the panic happens when calling __raw_notifier_call_chain at the second time. Kernel doesn't panic when calling it at the first time. If just say because of nr_cpu_ids, that's not right. By checking the source code, I found that function do_boot_cpu is the culprit. Consider below call chain: _cpu_up=>__cpu_up=>smp_ops.cpu_up=>native_cpu_up=>do_boot_cpu. So do_boot_cpu is called in the end. In do_boot_cpu, if boot_error==true, cpu_clear(cpu, cpu_possible_map) is executed. So later on, when _cpu_up calls __raw_notifier_call_chain at the second time to report CPU_UP_CANCELED, because this cpu is already cleared from cpu_possible_map, get_cpu_sysdev returns NULL. Many resources are related to cpu_possible_map, so it's better not to change it. Below patch against 2.6.26-rc7 fixes it by removing the bit clearing in cpu_possible_map.

the CPU hotplug problems (crashes under high-volume unplug+replug tests) seem to be related to migrate_dead_tasks(). Firstly I added traces to see all tasks being migrated with migrate_live_tasks() and migrate_dead_tasks(). On my setup the problem pops up (the one with "se == NULL" in the loop of pick_next_task_fair()) shortly after the traces indicate that some has been migrated with migrate_dead_tasks()). btw., I can reproduce it much faster now with just a plain cpu down/up loop. [disclaimer] Well, unless I'm really missing something important in this late hour [/desclaimer] pick_next_task() is not something appropriate for migrate_dead_tasks() :-) the following change seems to eliminate the problem on my setup (although, I kept it running only for a few minutes to get a few messages indicating migrate_dead_tasks() does move tasks and the system is still ok) Signed-off-by: Ingo Molnar <mingo@elte.hu>

Arjan van de Ven authored
The saa7134 driver uses a (non-atomic) variable in an attempt to only allow one opener of the device (how it deals with sending the fd over unix sockets I don't know). Unfortunately, the release function first decrements this variable, and THEN goes on to disable more of the device. This allows for a race where another opener of the device comes in after the decrement of the variable, configures the hardware just to then see the hardware be disabled by the rest of the release function. This patch makes the release function use the same lock as the open function to protect the hardware as well as the variable (which now at least has some locking to protect it).

cx18: Fix S-Video and Compsite input settings for the Yuan MPC718 per user reports from Yuri Warczynski <Yuri.Warczynski@gmail.com> and Brian Hope <brian@hopefamily.info> and enable the card entry. The tuner reset GPIO pin is likely incorrect as the tuner firmware cannot be reloaded without a reboot. It is likely the audio routing is done via GPIO which is not implemented yet, as users report audio doesn't work for some inputs.
