2012-12-07ASoC: Samsung: Do not register samsung audio dma device as pdevPadmavathi Venna15-23/+0
Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a platform_device. This didn't represent the hardware well, since there was no separate hardware associated with this platform_device; it was a virtual device with sole purpose to call snd_soc_register_platform(). This change removes the platform_device completely. Each Samsung DAI now registers the ASoC 'platform' itself. Machine drivers are adjusted for the new 'platform' name.

2012-12-05MIPS: Fix endless loop when processing signals for kernel tasksDmitry Adamushko1-1/+6
The problem occurs [1] when a kernel-mode task returns from a system call with a pending signal. A real-life scenario is a child of 'khelper' returning from a failed kernel_execve() in ____call_usermodehelper() [ kernel/kmod.c ]. kernel_execve() fails due to a pending SIGKILL, which is the result of "kill -9 -1" (at least, busybox's init does it upon reboot). The loop is as follows: * syscall_exit_work: - work_pending: // start_of_the_loop - work_notifysig: - do_notify_resume() - do_signal() - if (!user_mode(regs)) return; - resume_userspace // TIF_SIGPENDING is still set - work_pending // so we call work_pending => goto // start_of_the_loop More information can be found in another LKML thread: http://www.serverphorums.com/read.php?12,457826 [1] The problem was also reproduced on !CONFIG_VM86 x86, and the following fix was accepted. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=29a2e2836ff9ea65a603c89df217f4198973a74f Signed-off-by: Dmitry Adamushko <dmitry.adamushko@gmail.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/3571/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2012-12-04MIPS: Avoid mcheck by flushing page range in huge_ptep_set_access_flags()David Daney2-15/+15
Problem: 1) Huge page mapping of anonymous memory is initially invalid. Will be faulted in by copy-on-write mechanism. 2) Userspace attempts store at the end of the huge mapping. 3) TLB Refill exception handler fill TLB with a normal (4K sized) invalid page at the end of the huge mapping virtual address range. 4) Userspace restarted, and re-attempts the store at the end of the huge mapping. 5) Page from #3 is invalid, we get a fault and go to the hugepage fault handler. This tries to map a huge page and calls huge_ptep_set_access_flags() to install the mapping. 6) We just call the generic ptep_set_access_flags() to set up the page tables, but the flush there assumes a normal (4K sized) page and only tries to flush the first part of the huge page virtual address out of the TLB, since the existing entry from step #3 doesn't conflict, nothing is flushed. 7) We attempt to load the mapping into the TLB, but because it conflicts with the entry from step #3, we get a Machine Check exception. The fix: Flush the entire rage covered by the huge page in huge_ptep_set_access_flags(), and remove the optimization in local_flush_tlb_range() so that the flush actually does the correct thing.

2012-12-03sparc: Fix piggyback with newer binutils.David S. Miller1-6/+6
Newer versions of binutils mark '_end' as 'B' instead of 'A' for whatever reason. To be honest, the piggyback code doesn't actually care what kind of symbol _start and _end are, it just wants to find them and record the address. So remove the type from the match strings.

2012-11-30x86, fpu: Avoid FPU lazy restore after suspendVincent Palatin2-6/+14
When a cpu enters S3 state, the FPU state is lost. After resuming for S3, if we try to lazy restore the FPU for a process running on the same CPU, this will result in a corrupted FPU context. Ensure that "fpu_owner_task" is properly invalided when (re-)initializing a CPU, so nobody will try to lazy restore a state which doesn't exist in the hardware. Tested with a 64-bit kernel on a 4-core Ivybridge CPU with eagerfpu=off, by doing thousands of suspend/resume cycles with 4 processes doing FPU operations running. Without the patch, a process is killed after a few hundreds cycles by a SIGFPE.

2012-11-28ARM: 7586/1: sp804: set cpumask to cpu_possible_mask for clock event deviceWill Deacon1-1/+1
The SP804 driver statically initialises the cpumask of the clock event device to be cpu_all_mask, which is derived from the compile-time constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt controller handling the sp804 doesn't have the irq_set_affinity callback on the irq_chip, because the common timer code fails to identify the device as cpu-local and ends up treating it as a broadcast device instead. This patch fixes the problem by using cpu_possible_mask at runtime, which will correctly represent the possible CPUs when SMP_ON_UP is being used.

These 486 clones had only the FPU flag, if any, unlike the Intel 486s with CPUID, which also had VME and therefore needed CR4.

2012-11-23of/address: sparc: Declare of_iomap as an extern function for sparc againAndreas Larsson1-1/+4
This bug-fix makes sure that of_iomap is defined extern for sparc so that the sparc-specific implementation of_iomap is once again used when including include/linux/of_address.h in a sparc context. OF_GPIO that is now available for sparc relies on this. The bug was inadvertently introduced in a850a75, "of/address: add empty static inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when !CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c. This fix takes the same approach as 0bce04b that solved the equivalent problem for of_address_to_resource.

2012-11-23MIPS: Fix crash that occurs when function tracing is enabledAl Cooper1-4/+4
A recent patch changed some irq routines from inlines to functions. These routines are called by the tracer code. Now that they're functions, if they are compiled for function tracing they will call the tracer and crash the system due to infinite recursion. The fix disables tracing in these functions by using "notrace" in the function definition.
