2014-06-01ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory typeThomas Petazzoni
Due to a design incompatibility between the PCIe Marvell controller and the Cortex-A9, stressing PCIe devices with a lot of traffic quickly causes a deadlock. One part of the workaround for this is to have all PCIe regions mapped as strongly-ordered (MT_UNCACHED) instead of the default MT_DEVICE. While the arch_ioremap_caller() mechanism allows sub-architecture code to override ioremap(), used to map PCIe memory regions, there isn't such a mechanism to override the behavior of pci_ioremap_io(). This commit adds the arch_pci_ioremap_mem_type variable, initialized to MT_DEVICE by default, and that sub-architecture code can override. We have chosen to expose a single variable rather than offering the possibility of overriding the entire pci_ioremap_io(), because implementing pci_ioremap_io() requires calling functions (get_mem_type()) that are private to the arch/arm/mm/ code.

2014-05-30ARM: 8049/1: ftrace/add save_stack_trace_regs() implementationLin Yongting
When configure kprobe events of ftrace with "stacktrace" option enabled in arm, there is no stacktrace was recorded after the kprobe event was triggered. The root cause is no save_stack_trace_regs() function implemented. Implement the save_stack_trace_regs() function in arm, then ftrace will call this architecture-related function to record the stacktrace into ring buffer. After this fix, stacktrace can be recorded, for example: # mount -t debugfs nodev /sys/kernel/debug # echo "p:netrx net_rx_action" >> /sys/kernel/debug/tracing/kprobe_events # echo 1 > /sys/kernel/debug/tracing/events/kprobes/netrx/enable # echo 1 > /sys/kernel/debug/tracing/options/stacktrace # echo 1 > /sys/kernel/debug/tracing/tracing_on # ping 127.0.0.1 -c 1 # echo 0 > /sys/kernel/debug/tracing/tracing_on # cat /sys/kernel/debug/tracing/trace # tracer: nop # # entries-in-buffer/entries-written: 12/12 #P:1 # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / delay # TASK-PID CPU# |||| TIMESTAMP FUNCTION # | | | |||| | | <------ missing some entries ----------------> ping-1200 [000] dNs1 667.603250: netrx: (net_rx_action+0x0/0x1f8) ping-1200 [000] dNs1 667.604738: <stack trace> => net_rx_action => do_softirq => local_bh_enable => ip_finish_output => ip_output => ip_local_out => ip_send_skb => ip_push_pending_frames => raw_sendmsg => inet_sendmsg => sock_sendmsg => SyS_sendto => ret_fast_syscall Signed-off-by: Lin Yongting <linyongting@gmail.com> Acked-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2014-05-30ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instructionArun K S
We will reach fixup handler when one thread(say cpu0) caused an undefined exception, while another thread(say cpu1) is unmmaping the page. Fixup handler returns to the next userspace instruction which has caused the undef execption, rather than going to the same instruction. ARM ARM says that after undefined exception, the PC will be pointing to the next instruction. ie +4 offset in case of ARM and +2 in case of Thumb And there is no correction offset passed to vector_stub in case of undef exception. File: arch/arm/kernel/entry-armv.S +1085 vector_stub und, UND_MODE During an undefined exception, in normal scenario(ie when ldrt instruction does not cause an abort) after resorting the context in VFP hardware, the PC is modified as show below before jumping to ret_from_exception which is in r9. File: arch/arm/vfp/vfphw.S +169 @ The context stored in the VFP hardware is up to date with this thread vfp_hw_state_valid: tst r1, #FPEXC_EX bne process_exception @ might as well handle the pending @ exception before retrying branch @ out before setting an FPEXC that @ stops us reading stuff VFPFMXR FPEXC, r1 @ Restore FPEXC last sub r2, r2, #4 @ Retry current instruction - if Thumb str r2, [sp, #S_PC] @ mode it's two 16-bit instructions, @ else it's one 32-bit instruction, so @ always subtract 4 from the following @ instruction address. But if ldrt results in an abort, we reach the fixup handler and return to ret_from_execption without correcting the pc. This patch modifes the fixup handler to re-execute the same instruction which caused undefined execption.

2014-05-25ARM: 8053/1: kernel: sleep: restore HYP mode configuration in cpu_resumeLorenzo Pieralisi
On CPUs with virtualization extensions the kernel installs HYP mode configuration on both primary and secondary cpus upon cold boot. On platforms where CPUs are shutdown in idle paths (ie CPU core gating), when a CPU resumes from low-power states it currently does not execute code that reinstalls the HYP configuration, which means that the kernel cannot run eg KVM properly on such machines. This patch, mirroring cold-boot behaviour, executes position independent code that reinstalls HYP configuration and drops to SVC mode safely on warmboot, so that deep idle states can be enabled in kernel running as hosts on platforms with power management HW.

2014-05-25ARM: 8043/1: uprobes need icache flush after xol writeVictor Kamensky
After instruction write into xol area, on ARM V7 architecture code need to flush dcache and icache to sync them up for given set of addresses. Having just 'flush_dcache_page(page)' call is not enough - it is possible to have stale instruction sitting in icache for given xol area slot address. Introduce arch_uprobe_ixol_copy weak function that by default calls uprobes copy_to_page function and than flush_dcache_page function and on ARM define new one that handles xol slot copy in ARM specific way flush_uprobe_xol_access function shares/reuses implementation with/of flush_ptrace_access function and takes care of writing instruction to user land address space on given variety of different cache types on ARM CPUs. Because flush_uprobe_xol_access does not have vma around flush_ptrace_access was split into two parts. First that retrieves set of condition from vma and common that receives those conditions as flags. Note ARM cache flush function need kernel address through which instruction write happened, so instead of using uprobes copy_to_page function changed code to explicitly map page and do memcpy. Note arch_uprobe_copy_ixol function, in similar way as copy_to_user_page function, has preempt_disable/preempt_enable.

2014-05-22ARM: stacktrace: avoid listing stacktrace functions in stacktraceRussell King
While debugging the FEC ethernet driver using stacktrace, it was noticed that the stacktraces always begin as follows: [<c00117b4>] save_stack_trace_tsk+0x0/0x98 [<c0011870>] save_stack_trace+0x24/0x28 ... This is because the stack trace code includes the stack frames for itself. This is incorrect behaviour, and also leads to "skip" doing the wrong thing (which is the number of stack frames to avoid recording.) Perversely, it does the right thing when passed a non-current thread. Fix this by ensuring that we have a known constant number of frames above the main stack trace function, and always skip these.

2014-05-22ARM: dma-mapping: avoid calling dma_cache_maint_page() on dev=>cpuRussell King
Avoid calling dma_cache_maint_page() when unmapping a DMA_TO_DEVICE buffer. The L1 cache ops never do anything in this circumstance, nor do they ever need to - all that matters for this case is that the data written is visible to the device before DMA starts. What happens during the transfer (provided the buffer is not written to) is of no real consequence. We already do this optimisation for the L2 cache.

The bug is happened in cpu_v7_set_pte_ext(ptep, pte): An LPAE PTE is a 64bit quantity, passed to cpu_v7_set_pte_ext in the r2 and r3 registers. On an LE kernel, r2 contains the LSB of the PTE, and r3 the MSB. On a BE kernel, the assignment is reversed. Unfortunately, the current code always assumes the LE case, leading to corruption of the PTE when clearing/setting bits.

2014-04-23ARM: 8011/1: ARM hibernation / suspend-to-diskSebastian Capella
Enable hibernation for ARM architectures and provide ARM architecture specific calls used during hibernation. The swsusp hibernation framework depends on the platform first having functional suspend/resume. Then, in order to enable hibernation on a given platform, a platform_hibernation_ops structure may need to be registered with the system in order to save/restore any SoC-specific / cpu specific state needing (re)init over a suspend-to-disk/resume-from-disk cycle. For example: - "secure" SoCs that have different sets of control registers and/or different CR reg access patterns. - SoCs with L2 caches as the activation sequence there is SoC-dependent; a full off-on cycle for L2 is not done by the hibernation support code. - SoCs requiring steps on wakeup _before_ the "generic" parts done by cpu_suspend / cpu_resume can work correctly. - SoCs having persistent state which is maintained during suspend and resume, but will be lost during the power off cycle after suspend-to-disk.

2014-04-07Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAPUwe Kleine-König
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT.

2014-04-07ARM: 8009/1: dcscb.c: remove call to outer_flush_all()Nicolas Pitre
Strictly speaking this call is a no-op on the platform where dcscb.c is used since it only has architected caches. The call was there as a hint to people inspired by this code when writing their own backend, but the hint might not always be correct. For example, if a PL310 were to be used it wouldn't be safe to call the regular outer_flush_all() as atomic instructions for locking are involved in that case and those instructions cannot be assumed to still be operational after v7_exit_coherency_flush() has returned. Given no other CPUs (in the cluster) should be running at that point then standard concurrency concerns wouldn't apply. So let's simply kill this call for now and enhance the existing comment.
