Create the rdma directory in the staging area for use as we deprecate some older drivers and as we bring in some new drivers that are in need of work. Update the MAINTAINERS file so that updates to these files go to linux-rdma@vger.kernel.org. Expected lifespan of this directory is three releases for any deprecated drivers moved here and an unknown, but theoretically bounded amount of time for the new drivers as a new core RDMA transfer library needs to be written and the drivers modified to use it in order for them to move out of this directory.

Resolving a link-local IPv6 address with an unspecified source address was broken by commit 5462eddd, which prevented the IPv6 stack from learning the scope id of the link-local IPv6 address, causing random failures as the IP stack chose a random link to resolve the address on. This commit 5462eddd made us bail out of cma_check_linklocal early if the address passed in was not an IPv6 link-local address. On the address resolution path, the address passed in is the source address; if the source address is the unspecified address, which is not link-local, we will bail out early. This is mostly correct, but if the destination address is a link-local address, then we will be following a link-local route, and we'll need to tell the IPv6 stack what the scope id of the destination address is. This used to be done by last line of cma_check_linklocal, which is skipped when bailing out early: dev_addr->bound_dev_if = sin6->sin6_scope_id; (In cma_bind_addr, the sin6_scope_id of the source address is set to the sin6_scope_id of the destination address, so this is correct) This line is required in turn for the following line, L279 of addr6_resolve, to actually inform the IPv6 stack of the scope id: fl6.flowi6_oif = addr->bound_dev_if; Since we can only know we are in this failure case when we have access to both the source IPv6 address and destination IPv6 address, we have to deal with this further up the stack. So detect this failure case in cma_bind_addr, and set bound_dev_if to the destination address scope id to correct it.

On a math-emu bootup the following crash occurs: Initializing CPU#0 ------------[ cut here ]------------ kernel BUG at arch/x86/kernel/traps.c:779! invalid opcode: 0000 [#1] SMP [...] EIP is at do_device_not_available+0xe/0x70 [...] Call Trace: [<c18238e6>] error_code+0x5a/0x60 [<c1002bd0>] ? math_error+0x140/0x140 [<c100bbd9>] ? fpu__init_cpu+0x59/0xa0 [<c1012322>] cpu_init+0x202/0x330 [<c104509f>] ? __native_set_fixmap+0x1f/0x30 [<c1b56ab0>] trap_init+0x305/0x346 [<c1b548af>] start_kernel+0x1a5/0x35d [<c1b542b4>] i386_start_kernel+0x82/0x86 The reason is that in the following commit: b1276c48 ("x86/fpu: Initialize fpregs in fpu__init_cpu_generic()") I failed to consider math-emu's limitation that it cannot execute the FNINIT instruction in kernel mode. The long term fix might be to allow math-emu to execute (certain) kernel mode FPU instructions, but for now apply the safe (albeit somewhat ugly) fix: initialize the emulation state explicitly without trapping out to the FPU emulator.

Commit c48a11c7 ("netvm: propagate page->pfmemalloc to skb") added checks for page->pfmemalloc to __skb_fill_page_desc(): if (page->pfmemalloc && !page->mapping) skb->pfmemalloc = true; It assumes page->mapping == NULL implies that page->pfmemalloc can be trusted. However, __delete_from_page_cache() can set set page->mapping to NULL and leave page->index value alone. Due to being in union, a non-zero page->index will be interpreted as true page->pfmemalloc. So the assumption is invalid if the networking code can see such a page. And it seems it can. We have encountered this with a NFS over loopback setup when such a page is attached to a new skbuf. There is no copying going on in this case so the page confuses __skb_fill_page_desc which interprets the index as pfmemalloc flag and the network stack drops packets that have been allocated using the reserves unless they are to be queued on sockets handling the swapping which is the case here and that leads to hangs when the nfs client waits for a response from the server which has been dropped and thus never arrive. The struct page is already heavily packed so rather than finding another hole to put it in, let's do a trick instead. We can reuse the index again but define it to an impossible value (-1UL). This is the page index so it should never see the value that large. Replace all direct users of page->pfmemalloc by page_is_pfmemalloc which will hide this nastiness from unspoiled eyes. The information will get lost if somebody wants to use page->index obviously but that was the case before and the original code expected that the information should be persisted somewhere else if that is really needed (e.g. what SLAB and SLUB do).

Revert of a VBT parsing commit that should've been queued for drm-next, not v4.2. The revert unbreaks Braswell among other things. Also on Braswell removal of DP HBR2/TP3 and intermediate eDP frequency support. The code was optimistically added based on incorrect documentation; the platform does not support them. These are cc: stable. Finally a gpu state fix from Chris, also cc: stable. * tag 'drm-intel-fixes-2015-08-20' of git://anongit.freedesktop.org/drm-intel: drm/i915: Avoid TP3 on CHV drm/i915: remove HBR2 from chv supported list Revert "drm/i915: Add eDP intermediate frequencies for CHV" Revert "drm/i915: Allow parsing of variable size child device entries from VBT" drm/i915: Flag the execlists context object as dirty after every use

Meelis and Helge reported that 3a9ad0b4 ("PCI: Add pci_bus_addr_t") caused HPMCs on A500 and hangs on rp5470. PA-RISC does not set ARCH_DMA_ADDR_T_64BIT, even for 64-bit kernels, so prior to 3a9ad0b4, we always used 32-bit PCI addresses. After 3a9ad0b4, we do use 64-bit PCI addresses in 64-bit kernels, and apparently there's some PA-RISC problem related to them.

Commit b253149b ("sched/idle/x86: Restore mwait_idle() to fix boot hangs, to improve power savings and to improve performance") restores mwait_idle(), but the trace_cpu_idle related calls are missing. This causes powertop on my old desktop powered by Intel Core2 E6550 to report zero wakeups and zero events. Add them back to restore the proper behaviour.
