Old KVM guests invoke single-context invvpid without actually checking whether it is supported. This was fixed by commit 518c8ae ("KVM: VMX: Make sure single type invvpid is supported before issuing invvpid instruction", 2010-08-01) and the patch after, but pre-2.6.36 kernels lack it including RHEL 6.

Discard policy uses ack_notifiers to prevent injection of PIT interrupts before EOI from the last one. This patch changes the policy to always try to deliver the interrupt, which makes a difference when its vector is in ISR. Old implementation would drop the interrupt, but proposed one injects to IRR, like real hardware would. The old policy breaks legacy NMI watchdogs, where PIT is used through virtual wire (LVT0): PIT never sends an interrupt before receiving EOI, thus a guest deadlock with disabled interrupts will stop NMIs. Note that NMI doesn't do EOI, so PIT also had to send a normal interrupt through IOAPIC. (KVM's PIT is deeply rotten and luckily not used much in modern systems.) Even though there is a chance of regressions, I think we can fix the LVT0 NMI bug without introducing a new tick policy.

Signal delivery needs to know the sign of an interrupted syscall's return value in order to detect -ERESTART variants. Normally this works independently of bitness because syscalls internally return long. Under ptrace, however, this can break, and syscall_get_error is supposed to sign-extend regs->ax if needed. We were clearing TS_COMPAT too early, though, and this prevented sign extension, which subtly broke syscall restart under ptrace.

So untangle it from the BLK_DEV_INITRD dependency so that oldconfig doesn't turn it off and add an explanatory text to its Kconfig help what the supported methods for supplying microcode are.

ARM64 allmodconfig produces a bunch of warnings when building the samsung ASoC code: sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data': sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] playback_data->filter_data = (void *)playback->channel; sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] capture_data->filter_data = (void *)capture->channel; We could easily shut up the warning by adding an intermediate cast, but there is a bigger underlying problem: The use of IORESOURCE_DMA to pass data from platform code to device drivers is dubious to start with, as what we really want is a pointer that can be passed into a filter function. Note that on s3c64xx, the pl08x DMA data is already a pointer, but gets cast to resource_size_t so we can pass it as a resource, and it then gets converted back to a pointer. In contrast, the data we pass for s3c24xx is an index into a device specific table, and we artificially convert that into a pointer for the filter function.

Although the arm64 vDSO is cleanly separated by code/data with the code being read-only in userspace mappings, the code page is still writable from the kernel. There have been exploits (such as http://itszn.com/blog/?p=21) that take advantage of this on x86 to go from a bad kernel write to full root. Prevent this specific exploit on arm64 by putting the vDSO code page in read-only memory as well.
