e389302 Helge Deller 08 April 2016, 16:11:33 UTC parisc: Avoid function pointers for kernel exception routines We want to avoid the kernel module loader to create function pointers for the kernel fixup routines of get_user() and put_user(). Changing the external reference from function type to int type fixes this. This unbreaks exception handling for get_user() and put_user() when called from a kernel module.

592570c Helge Deller 08 April 2016, 20:10:35 UTC parisc: Handle R_PARISC_PCREL32 relocations in kernel modules Commit 0de7985 (parisc: Use generic extable search and sort routines) changed the exception tables to use 32bit relative offsets. This patch now adds support to the kernel module loader to handle such R_PARISC_PCREL32 relocations for 32- and 64-bit modules. Signed-off-by: Helge Deller <deller@gmx.de> 08 April 2016, 20:10:35 UTC
3c96888 Bart Van Assche 07 April 2016, 22:55:04 UTC Revert "ib_srpt: Convert to percpu_ida tag allocation" This reverts commit 0fd10721fe3664f7549e74af9d28a509c9a68719. That patch causes the ib_srpt driver to crash as soon as the first SCSI command is received: kernel BUG at drivers/infiniband/ulp/srpt/ib_srpt.c:1439! invalid opcode: 0000 [#1] SMP Workqueue: target_completion target_complete_ok_work [target_core_mod] RIP: srpt_queue_response+0x437/0x4a0 [ib_srpt] Call Trace: srpt_queue_data_in+0x9/0x10 [ib_srpt] target_complete_ok_work+0x152/0x2b0 [target_core_mod] process_one_work+0x197/0x480 worker_thread+0x49/0x490 kthread+0xea/0x100 ret_from_fork+0x22/0x40 Aside from the crash, the shortcomings of that patch are as follows: - It makes the ib_srpt driver use I/O contexts allocated by transport_alloc_session_tags() but it does not initialize these I/O contexts properly. All the initializations performed by srpt_alloc_ioctx() are skipped. - It swaps the order of the send ioctx allocation and the transition to RTR mode which is wrong. - The amount of memory that is needed for I/O contexts is doubled. - srpt_rdma_ch.free_list is no longer used but is not removed.

c00bbcf Stefan Hajnoczi 29 March 2016, 15:43:45 UTC virtio: add VIRTIO_CONFIG_S_NEEDS_RESET device status bit The VIRTIO 1.0 specification added the DEVICE_NEEDS_RESET device status bit in "VIRTIO-98: Add DEVICE_NEEDS_RESET". This patch defines the device status bit in the uapi header file so that both the kernel and userspace applications can use it. The bit is currently unused by the virtio guest drivers and vhost. According to the spec "a good implementation will try to recover by issuing a reset". This is not attempted here because it requires auditing the virtio drivers to ensure there are no resource leaks or crashes if the device needs to be reset mid-operation. See "2.1 Device Status Field" in the VIRTIO 1.0 specification for details. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Michael S.

I doubt anybody uses this, and it does expose addresses that should be randomized, so let's just remove the code. It's old and traditional, and it used to be cute, but we should have removed this long ago. If it turns out anybody notices and this breaks something, we'll have to revert this, and maybe we'll end up using other approaches instead (using %pK or similar).

This adds an 'else' clause for the case we get the warning about, causing the function to return an error in a controlled way.

61abdbe Luiz Capitulino 04 April 2016, 20:46:07 UTC kvm: x86: make lapic hrtimer pinned When a vCPU runs on a nohz_full core, the hrtimer used by the lapic emulation code can be migrated to another core. When this happens, it's possible to observe milisecond latency when delivering timer IRQs to KVM guests. The huge latency is mainly due to the fact that apic_timer_fn() expects to run during a kvm exit. It sets KVM_REQ_PENDING_TIMER and let it be handled on kvm entry. However, if the timer fires on a different core, we have to wait until the next kvm exit for the guest to see KVM_REQ_PENDING_TIMER set. This problem became visible after commit 9642d18ee. This commit changed the timer migration code to always attempt to migrate timers away from nohz_full cores. While it's discussable if this is correct/desirable (I don't think it is), it's clear that the lapic emulation code has a requirement on firing the hrtimer in the same core where it was started. This is achieved by making the hrtimer pinned. Lastly, note that KVM has code to migrate timers when a vCPU is scheduled to run in different core. However, this forced migration may fail. When this happens, we can have the same problem. If we want 100% correctness, we'll have to modify apic_timer_fn() to cause a kvm exit when it runs on a different core than the vCPU. Not sure if this is possible. Here's a reproducer for the issue being fixed: 1. Set all cores but core0 to be nohz_full cores 2. Start a guest with a single vCPU 3. Trace apic_timer_fn() and kvm_inject_apic_timer_irqs() You'll see that apic_timer_fn() will run in core0 while kvm_inject_apic_timer_irqs() runs in a different core. If you get both on core0, try running a program that takes 100% of the CPU and pin it to core0 to force the vCPU out.

Together with that move, i2c_dp_aux_add_bus() was marked deprecated and started warning about its remaining use. It's now been a year and a half of annoying warning, and apparently nobody cares enough about gma500 to try to move it along to the more modern models. Get rid of the warning - if even the gma500 people don't care enough, then they should certainly not spam other innocent developers with a warning that might hide other, much more real issues.

09cbfea Kirill A. Shutemov 01 April 2016, 12:29:47 UTC mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago with promise that one day it will be possible to implement page cache with bigger chunks than PAGE_SIZE. This promise never materialized. And unlikely will. We have many places where PAGE_CACHE_SIZE assumed to be equal to PAGE_SIZE. And it's constant source of confusion on whether PAGE_CACHE_* or PAGE_* constant should be used in a particular case, especially on the border between fs and mm. Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much breakage to be doable. Let's stop pretending that pages in page cache are special. They are not. The changes are pretty straight-forward: - <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN}; - page_cache_get() -> get_page(); - page_cache_release() -> put_page(); This patch contains automated changes generated with coccinelle using script below. For some reason, coccinelle doesn't patch header files. I've called spatch for them manually. The only adjustment after coccinelle is revert of changes to PAGE_CAHCE_ALIGN definition: we are going to drop it later. There are few places in the code where coccinelle didn't reach. I'll fix them manually in a separate patch. Comments and documentation also will be addressed with the separate patch. virtual patch @@ expression E; @@ - E << (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ expression E; @@ - E >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ @@ - PAGE_CACHE_SHIFT + PAGE_SHIFT @@ @@ - PAGE_CACHE_SIZE + PAGE_SIZE @@ @@ - PAGE_CACHE_MASK + PAGE_MASK @@ expression E; @@ - PAGE_CACHE_ALIGN(E) + PAGE_ALIGN(E) @@ expression E; @@ - page_cache_get(E) + get_page(E) @@ expression E; @@ - page_cache_release(E) + put_page(E) Signed-off-by: Kirill A.

ff1e22e Boris Ostrovsky 18 March 2016, 14:11:07 UTC xen/events: Mask a moving irq Moving an unmasked irq may result in irq handler being invoked on both source and target CPUs. With 2-level this can happen as follows: On source CPU: evtchn_2l_handle_events() -> generic_handle_irq() -> handle_edge_irq() -> eoi_pirq(): irq_move_irq(data); /***** WE ARE HERE *****/ if (VALID_EVTCHN(evtchn)) clear_evtchn(evtchn); If at this moment target processor is handling an unrelated event in evtchn_2l_handle_events()'s loop it may pick up our event since target's cpu_evtchn_mask claims that this event belongs to it *and* the event is unmasked and still pending. At the same time, source CPU will continue executing its own handle_edge_irq(). With FIFO interrupt the scenario is similar: irq_move_irq() may result in a EVTCHNOP_unmask hypercall which, in turn, may make the event pending on the target CPU. We can avoid this situation by moving and clearing the event while keeping event masked.

04211a5 Paul Burton 04 February 2016, 13:05:02 UTC MIPS: Bail on unsupported module relocs When an unsupported reloc is encountered in a module, we currently blindly branch to whatever would be at its entry in the reloc handler function pointer arrays. This may be NULL, or if the unsupported reloc has a type greater than that of the supported reloc with the highest type then we'll dereference some value after the function pointer array & branch to that. The result is at best a kernel oops. Fix this by checking that the reloc type has an entry in the function pointer array (ie. is less than the number of items in the array) and that the handler is non-NULL, returning an error code to fail the module load if no handler is found.

The ar724x_clocks_init() function recreates the clocks from scratch so devicetree clock information is dropped. After adding the code which picked up reference clock from devicetree I have found that kernel does not boot anymore. The SPI and UART drivers can't get clk; here are the bootlog error messages: of_serial: probe of 18020000.uart failed with error -22 ath79-spi: probe of 1f000000.spi failed with error -22 The problem is that clock code assumes that reference clock name is "ref" but current dts-file uses another name: "oscillator". This patch fixes the problem by changing external oscillator dt node name to "ref".

f4c87b7 Alban Bedel 17 March 2016, 03:34:10 UTC MIPS: ath79: Fix the ar913x reference clock rate The reference clock on ar913x is at 40MHz and not 5MHz. The current implementation use the wrong reference rate because it doesn't take the PLL divider in account. But if we fix the code to use the divider it becomes identical with the implementation for ar724x, so just drop the broken ar913x implementation.

The correct CPU PLL calculation procedure is as follows: CPU_PLL = (FB * REF_CLK) / REF_DIV / 2. This patch is compatible with the current calculation procedure with default FB and REF_DIV values.

Keep Trap exceptions unaffected as these are not debug events. No existing user software is expected to examine signal codes for these signals as SI_KERNEL has been always used here.

858eaaa Nadav Amit 01 April 2016, 21:31:26 UTC mm/rmap: batched invalidations should use existing api The recently introduced batched invalidations mechanism uses its own mechanism for shootdown. However, it does wrong accounting of interrupts (e.g., inc_irq_stat is called for local invalidations), trace-points (e.g., TLB_REMOTE_SHOOTDOWN for local invalidations) and may break some platforms as it bypasses the invalidation mechanisms of Xen and SGI UV. This patch reuses the existing TLB flushing mechnaisms instead. We use NULL as mm to indicate a global invalidation is required.

db5dd0d Marcin Wojtas 01 April 2016, 13:21:18 UTC net: mvneta: fix changing MTU when using per-cpu processing After enabling per-cpu processing it appeared that under heavy load changing MTU can result in blocking all port's interrupts and transmitting data is not possible after the change. This commit fixes above issue by disabling percpu interrupts for the time, when TXQs and RXQs are reconfigured. Signed-off-by: Marcin Wojtas <mw@semihalf.com> Signed-off-by: David S.
