This fixes some bugs in emulate_step(). First, the setting of the carry bit for the arithmetic right-shift instructions was not correct on 64-bit machines because we were masking with a mask of type int rather than unsigned long. Secondly, the sld (shift left doubleword) instruction was using the wrong instruction field for the register containing the shift count. Signed-off-by:

These processors do not currently support doorbell IPIs, so remove them from the feature list if we are at DD 1.xx for the 0x004d part. This fixes a regression caused by d4e58e59 (powerpc/powernv: Enable POWER8 doorbell IPIs). With that patch the kernel would hang at boot when calling smp_call_function_many, as the doorbell would not be received by the target CPUs: .smp_call_function_many+0x2bc/0x3c0 (unreliable) .on_each_cpu_mask+0x30/0x100 .cpuidle_register_driver+0x158/0x1a0 .cpuidle_register+0x2c/0x110 .powernv_processor_idle_init+0x23c/0x2c0 .do_one_initcall+0xd4/0x260 .kernel_init_freeable+0x25c/0x33c .kernel_init+0x1c/0x120 .ret_from_kernel_thread+0x58/0x7c Fixes: d4e58e59 (powerpc/powernv: Enable POWER8 doorbell IPIs) Signed-off-by:

We are seeing a lot of PMU warnings on POWER8: Can't find PMC that caused IRQ Looking closer, the active PMC is 0 at this point and we took a PMU exception on the transition from negative to 0. Some versions of POWER8 have an issue where they edge detect and not level detect PMC overflows. A number of places program the PMC with (0x80000000 - period_left), where period_left can be negative. We can either fix all of these or just ensure that period_left is always >= 1. This patch takes the second option.

powerpc:allmodconfig has been failing for some time with the following error. arch/powerpc/kernel/exceptions-64s.S: Assembler messages: arch/powerpc/kernel/exceptions-64s.S:1312: Error: attempt to move .org backwards make[1]: *** [arch/powerpc/kernel/head_64.o] Error 1 A number of attempts to fix the problem by moving around code have been unsuccessful and resulted in failed builds for some configurations and the discovery of toolchain bugs. Fix the problem by disabling RELOCATABLE for COMPILE_TEST builds instead. While this is less than perfect, it avoids substantial code changes which would otherwise be necessary just to make COMPILE_TEST builds happy and might have undesired side effects. Signed-off-by:

On POWER8 when switching to a KVM guest we set bits in MMCR2 to freeze the PMU counters. Aside from on boot they are then never reset, resulting in stuck perf counters for any user in the guest or host. We now set MMCR2 to 0 whenever enabling the PMU, which provides a sane state for perf to use the PMU counters under either the guest or the host. This was manifesting as a bug with ppc64_cpu --frequency: $ sudo ppc64_cpu --frequency WARNING: couldn't run on cpu 0 WARNING: couldn't run on cpu 8 ... WARNING: couldn't run on cpu 144 WARNING: couldn't run on cpu 152 min: 18446744073.710 GHz (cpu -1) max: 0.000 GHz (cpu -1) avg: 0.000 GHz The command uses a perf counter to measure CPU cycles over a fixed amount of time, in order to approximate the frequency of the machine. The counters were returning zero once a guest was started, regardless of weather it was still running or had been shut down. By dumping the value of MMCR2, it was observed that once a guest is running MMCR2 is set to 1s - which stops counters from running: $ sudo sh -c 'echo p > /proc/sysrq-trigger' CPU: 0 PMU registers, ppmu = POWER8 n_counters = 6 PMC1: 5b635e38 PMC2: 00000000 PMC3: 00000000 PMC4: 00000000 PMC5: 1bf5a646 PMC6: 5793d378 PMC7: deadbeef PMC8: deadbeef MMCR0: 0000000080000000 MMCR1: 000000001e000000 MMCRA: 0000040000000000 MMCR2: fffffffffffffc00 EBBHR: 0000000000000000 EBBRR: 0000000000000000 BESCR: 0000000000000000 SIAR: 00000000000a51cc SDAR: c00000000fc40000 SIER: 0000000001000000 This is done unconditionally in book3s_hv_interrupts.S upon entering the guest, and the original value is only save/restored if the host has indicated it was using the PMU. This is okay, however the user of the PMU needs to ensure that it is in a defined state when it starts using it.

These two registers are already saved in the block above. Aside from being unnecessary, by the time we get down to the second save location r8 no longer contains MMCR2, so we are clobbering the saved value with PMC5. MMCR2 primarily consists of counter freeze bits. So restoring the value of PMC5 into MMCR2 will most likely have the effect of freezing counters.

Commit 8d6f7c5a: "powerpc/powernv: Make it possible to skip the IRQHAPPENED check in power7_nap()" added code that prevents cpus from checking for pending interrupts just before entering sleep state, which is wrong. These interrupts are delivered during the soft irq disabled state of the cpu. A cpu cannot enter any idle state with pending interrupts because they will never be serviced until the next time the cpu is woken up by some other interrupt. Its only then that the pending interrupts are replayed. This can result in device timeouts or warnings about this cpu being stuck. This patch fixes ths issue by ensuring that cpus check for pending interrupts just before entering any idle state as long as they are not in the path of split core operations. Signed-off-by:

The commit 71ec7c55 introduced the magic symbol ".TOC." for ELFv2 ABI. This symbol is built manually and has no CRC value computed. A zero value is put in the CRC section to avoid modpost complaining about a missing CRC. Unfortunately, this breaks the kernel module loading when the kernel is relocated (kdump case for instance) because of the relocation applied to the kcrctab values. This patch compute a CRC value for the TOC symbol which will match the one compute by the kernel when it is relocated - aka '0 - relocate_start' done in maybe_relocated called by check_version (module.c).

In commit 27f44888 "Add OPAL takeover from PowerVM" we added support for "takeover" on OPAL v1 machines. This was a mode of operation where we would boot under pHyp, and query for the presence of OPAL. If detected we would then do a special sequence to take over the machine, and the kernel would end up running in hypervisor mode. OPAL v1 was never a supported product, and was never shipped outside IBM. As far as we know no one is still using it. Newer versions of OPAL do not use the takeover mechanism. Although the query for OPAL should be harmless on machines with newer OPAL, we have seen a machine where it causes a crash in Open Firmware. The code in early_init_devtree() to copy boot_command_line into cmd_line was added in commit 817c21ad "Get kernel command line accross OPAL takeover", and AFAIK is only used by takeover, so should also be removed.

In commit 721aeaa9 "Build little endian ppc64 kernel with ABIv2", we missed some updates required in the kprobes code to make jprobes work when the kernel is built with ABI v2. Firstly update arch_deref_entry_point() to do the right thing. Now that we have added ppc_global_function_entry() we can just always use that, it will do the right thing for 32 & 64 bit and ABI v1 & v2. Secondly we need to update the code that sets up the register state before calling the jprobe handler. On ABI v1 we setup r2 to hold the TOC, on ABI v2 we need to populate r12 with the function entry point address. Signed-off-by:

There is a bug in the handling of the function entry when we are nopping out a branch from a module in ftrace. We compare the result of module_trampoline_target() with the value of ppc_function_entry(), and expect them to be true. But they never will be. module_trampoline_target() will always return the global entry point of the function, whereas ppc_function_entry() will always return the local. Fix it by using the newly added ppc_global_function_entry(). Signed-off-by:

In commit 24a1bdc3, "Fix ABIv2 issues with __ftrace_make_call", Anton changed the logic that creates and patches the branch, and added a thinko in the check of create_branch(). create_branch() returns the instruction that was generated, so if we get zero then it succeeded.

In commit 24a1bdc3, "Fix ABIv2 issues with __ftrace_make_call", Anton changed the logic that checks for the expected code sequence when patching a module. We missed the typo in the mask, 0xffff00000 should be 0xffff0000, which has the effect of making the test always true.

ABIv2 has the concept of a global and local entry point to a function. In most cases we are interested in the local entry point, and so that is what ppc_function_entry() returns. However we have a case in the ftrace code where we want the global entry point, and there may be other places we need it too. Rather than special casing each, add an accessor. For ABIv1 and 32-bit there is only a single entry point, so we return that. That means it's safe for the caller to use this without also checking the ABI version. Signed-off-by:

This reverts commit e1edf18b. This patch was a misguided attempt at fixing offb for LE ppc64 kernels on BE qemu but is just wrong ... it breaks real LE/LE setups, LE with real HW, and existing mixed endian systems that did the fight thing with the appropriate device-tree property. Bad reviewing on my part, sorry. The right fix is to either make qemu change its endian when the guest changes endian (working on that) or to use the existing foreign endian support. Signed-off-by:

Commit 3fd091e7 ("[SCTP]: Remove multiple levels of msecs to jiffies conversions.") has silently changed permissions for rto_alpha and rto_beta knobs from 0644 to 0444. The purpose of this was to discourage users from tweaking rto_alpha and rto_beta knobs in production environments since they are key to correctly compute rtt/srtt. RFC4960 under section 6.3.1. RTO Calculation says regarding rto_alpha and rto_beta under rule C3 and C4: [...] C3) When a new RTT measurement R' is made, set RTTVAR <- (1 - RTO.Beta) * RTTVAR + RTO.Beta * |SRTT - R'| and SRTT <- (1 - RTO.Alpha) * SRTT + RTO.Alpha * R' Note: The value of SRTT used in the update to RTTVAR is its value before updating SRTT itself using the second assignment. After the computation, update RTO <- SRTT + 4 * RTTVAR. C4) When data is in flight and when allowed by rule C5 below, a new RTT measurement MUST be made each round trip. Furthermore, new RTT measurements SHOULD be made no more than once per round trip for a given destination transport address. There are two reasons for this recommendation: First, it appears that measuring more frequently often does not in practice yield any significant benefit [ALLMAN99]; second, if measurements are made more often, then the values of RTO.Alpha and RTO.Beta in rule C3 above should be adjusted so that SRTT and RTTVAR still adjust to changes at roughly the same rate (in terms of how many round trips it takes them to reflect new values) as they would if making only one measurement per round-trip and using RTO.Alpha and RTO.Beta as given in rule C3. However, the exact nature of these adjustments remains a research issue. [...] While it is discouraged to adjust rto_alpha and rto_beta and not further specified how to adjust them, the RFC also doesn't explicitly forbid it, but rather gives a RECOMMENDED default value (rto_alpha=3, rto_beta=2). We have a couple of users relying on the old permissions before they got changed. That said, if someone really has the urge to adjust them, we could allow it with a warning in the log.

Geert reported issues regarding checksum complete and UDP. The logic introduced in commit 7e3cead5 ("net: Save software checksum complete") is not correct. This patch: 1) Restores code in __skb_checksum_complete_header except for setting CHECKSUM_UNNECESSARY. This function may be calculating checksum on something less than skb->len. 2) Adds saving checksum to __skb_checksum_complete. The full packet checksum 0..skb->len is calculated without adding in pseudo header. This value is saved in skb->csum and then the pseudo header is added to that to derive the checksum for validation. 3) In both __skb_checksum_complete_header and __skb_checksum_complete, set skb->csum_valid to whether checksum of zero was computed. This allows skb_csum_unnecessary to return true without changing to CHECKSUM_UNNECESSARY which was done previously. 4) Copy new csum related bits in __copy_skb_header. Reported-by:
