Test a couple of special cases in 32-bit kernels for entries from vm86 mode. This will OOPS both old kernels due to a bug and and 4.1-rc5 due to a regression I introduced, and it should make sure that the SYSENTER-from-vm86-mode hack in the kernel keeps working.

Linus reported the following new warning on x86 allmodconfig with GCC 5.1: > ./arch/x86/include/asm/spinlock.h: In function ‘arch_spin_lock’: > ./arch/x86/include/asm/spinlock.h:119:3: warning: implicit declaration > of function ‘__ticket_lock_spinning’ [-Wimplicit-function-declaration] > __ticket_lock_spinning(lock, inc.tail); > ^ This warning triggers because of these hacks in misc.h: /* * we have to be careful, because no indirections are allowed here, and * paravirt_ops is a kind of one. As it will only run in baremetal anyway, * we just keep it from happening */ #undef CONFIG_PARAVIRT #undef CONFIG_KASAN But these hacks were not updated when CONFIG_PARAVIRT_SPINLOCKS was added, and eventually (with the introduction of queued paravirt spinlocks in recent kernels) this created an invalid Kconfig combination and broke the build. So add a CONFIG_PARAVIRT_SPINLOCKS #undef line as well. Also remove the _ASM_X86_DESC_H quirk: that undocumented quirk was originally added ages ago, in: 099e1377 ("x86: use ELF format in compressed images.") and I went back to that kernel (and fixed up the main Makefile which didn't build anymore) and checked what failure it avoided: it avoided an include file dependencies related build failure related to our old x86-platforms code. That old code is long gone, the header dependencies got cleaned up, and the build does not fail anymore with the totality of asm/desc.h included - so remove the quirk.

sctp_v4_map_v6 was subtly writing and reading from members of a union in a way the clobbered data it needed to read before it read it. Zeroing the v6 flowinfo overwrites the v4 sin_addr with 0, meaning that every place that calls sctp_v4_map_v6 gets ::ffff:0.0.0.0 as the result. Reorder things to guarantee correct behaviour no matter what the union layout is. This impacts user space clients that open an IPv6 SCTP socket and receive IPv4 connections. Prior to 299ee user space would see a sockaddr with AF_INET and a correct address, after 299ee the sockaddr is AF_INET6, but the address is wrong.

For mq qdisc, we add per tx queue qdisc to root qdisc for display purpose, however, that happens too early, before the new dev->qdisc is finally set, this causes q->list points to an old root qdisc which is going to be freed right before assigning with a new one.

The srm console is always built in. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Direct use of __initcall is discouraged, vs prioritized ones. Use of device_initcall is consistent with what __initcall maps onto, and hence does not change the init order, making the impact of this change zero. Should someone with real hardware for boot testing want to change it later to arch_initcall or console_initcall, they can do that at a later date.

PCI core will initialize device MSI/MSI-X capability in pci_msi_init_pci_dev(). So device driver should use pci_dev->msi_cap/msix_cap to determine whether the device support MSI/MSI-X instead of using pci_find_capability(pci_dev, PCI_CAP_ID_MSI/MSIX). Access to PCIe device config space again will consume more time.

The newly added AEAD user-space isn't quite ready for prime time just yet. In particular it is conflicting with the AEAD single SG list interface change so this patch disables it now. Once the SG list stuff is completely done we can then renable this interface. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

When trying to request the PWM device with devm_pwm_get(), the EPROBE_DEFER flag is not handled properly. It can lead to the PWM not being found.

A pair of nested spin locks was introduced in commit 63502b8d "dp83640: Fix receive timestamp race condition". Unfortunately the 'flags' parameter was reused for the inner lock, clobbering the originally saved IRQ state. This patch fixes the issue by changing the inner lock to plain spin_lock without irqsave.

Callers of the ext_write function are supposed to hold a mutex that protects the state of the dialed page, but one caller was missing the lock from the very start, and over time the code has been changed without following the rule. This patch cleans up the call sites in violation of the rule. Signed-off-by: NRichard Cochran <richardcochran@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Currently, the calibration function that corrects the initial offsets among multiple devices only works the first time. If the function is called more than once, the calibration fails and bogus offsets will be programmed into the devices. In a well hidden spot, the device documentation tells that trigger indexes 0 and 1 are special in allowing the TRIG_IF_LATE flag to actually work. This patch fixes the issue by using one of the special triggers during the recalibration method. Signed-off-by: NRichard Cochran <richardcochran@gmail.com> Signed-off-by: NDavid S.
