gcc finds that the i40iw_make_cm_node() function in the recently added i40iw driver uses an uninitilized variable as an index into an array if CONFIG_IPV6 is disabled and the driver uses IPv6 mode: drivers/infiniband/hw/i40iw/i40iw_cm.c: In function 'i40iw_make_cm_node': drivers/infiniband/hw/i40iw/i40iw_cm.c:2206:52: error: 'arpindex' may be used uninitialized in this function [-Werror=maybe-uninitialized] ether_addr_copy(cm_node->rem_mac, iwdev->arp_table[arpindex].mac_addr); As far as I can tell, this code path can not be used because the ipv4 variable is always set with CONFIG_IPV6 is disabled, but it's better to be sure and prevent the undefined behavior, as well as shut up that warning in a proper way. This adds an 'else' clause for the case we get the warning about, causing the function to return an error in a controlled way. To avoid adding extra mess with combined io()/#ifdef clauses, I'm also converting the existing #ifdef into a more readable if(IS_ENABLED()) check. Signed-off-by:

The previous patch that added a couple of callback functions put the declarations inside of an #ifdef CONFIG_INFINIBAND_ON_DEMAND_PAGING, which causes the build to fail if that option is disabled: drivers/infiniband/hw/mlx5/main.c: In function 'mlx5_ib_add': drivers/infiniband/hw/mlx5/main.c:2358:31: error: 'mlx5_ib_get_vf_config' undeclared (first use in this function) This moves the four declarations below the #ifdef section so they are always available.

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 9642d18e . 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. Signed-off-by:

In commit e4570897 ("drm/dp-helper: Move the legacy helpers to gma500") the legacy i2c helpers were moved to the only remaining user of them, the gma500 driver. 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.

As Kirill suggested as a possibility, I could have decided to only merge the first two patches, and leave the old interfaces for compatibility, but I'd rather get it all done and any out-of-tree modules and patches can trivially do the converstion while still also working with older kernels, so there is little reason to try to maintain the redundant legacy model. - Linus ] * PAGE_CACHE_SIZE-removal: mm: drop PAGE_CACHE_* and page_cache_{get,release} definition mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage 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.

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. Signed-off-by:

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 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. Signed-off-by:

According to the AR7242 datasheet section 2.8, AR724X CPUs use a 40MHz input clock as the REF_CLK instead of 5MHz. 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. Tested on AR7240, AR7241 and AR7242. Signed-off-by:

Follow our own rules set in <asm/siginfo.h> for SIGTRAP signals issued from `do_watch' and `do_trap_or_bp' by setting the signal code to TRAP_HWBKPT and TRAP_BRKPT respectively, for Watch exceptions and for those Breakpoint exceptions whose originating BREAK instruction's code does not have a special meaning. 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. This change makes the MIPS port more like other Linux ports, which reduces the complexity and provides for performance improvement in GDB. Signed-off-by:
