The revert of 991de2e5 ("PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq()") causes a problem for IOAPIC hotplug. The problem is that IRQs are allocated and freed in pci_enable_device() and pci_disable_device(). But there are some drivers which don't call pci_disable_device(), and they have good reasons not calling it, so if they're using IOAPIC their IRQs won't have a chance to be released from the IOAPIC. When this happens IOAPIC hot-removal fails with a kernel stack dump and an error message like this: [149335.697989] pin16 on IOAPIC2 is still in use. It turns out that we can fix it in a different way without moving IRQ allocation into pcibios_alloc_irq(), thus avoiding the regression of 991de2e5. We can keep the allocation and freeing of IRQs as is within pci_enable_device()/pci_disable_device(), without breaking any previous assumption of the rest of the system, keeping compatibility with both the legacy and the modern drivers. We can accomplish this by implementing the existing __weak hook of pcibios_release_device() thus when a pci device is about to be deleted we get notified in the hook and take the chance to release its IRQ, if any, from the IOAPIC. Implement pcibios_release_device() for x86 to release any IRQ not released by the driver.

Kernel erases R8..R11 registers prior returning to userspace from int80: https://lkml.org/lkml/2009/10/1/164 GCC can reuse these registers and doesn't expect them to change during syscall invocation. I met this kind of bug in CRIU once GCC 6.1 and CLANG stored local variables in those registers and the kernel zerofied them during syscall: https://github.com/xemul/criu/commit/990d33f1a1cdd17bca6c2eb059ab3be2564f7fa2 By that reason I suggest to add those registers to clobbers in selftests. Also, as noted by Andy - removed unneeded clobber for flags in INT $0x80 inline asm.

The following commit: 2e63ad4b ("x86/apic: Do not init irq remapping if ioapic is disabled") ... added a check for skipped IO-APIC setup to enable_IR_x2apic(), but this check is also duplicated in try_to_enable_IR() - and it will never succeed in calling irq_remapping_enable(). Remove the whole irq_remapping_enable() complication: if the IO-APIC is disabled we cannot enable IRQ remapping.

The current warning message in allocate_logical_cpuid() is somewhat confusing: Only 1 processors supported.Processor 2/0x2 and the rest are ignored. As it might imply that there's only one CPU in the system - while what we ran into here is a kernel limitation. Fix the warning message to clarify all that: APIC: NR_CPUS/possible_cpus limit of 2 reached. Processor 2/0x2 and the rest are ignored. ( Also update the error return from -1 to -EINVAL, which is the more canonical return value. ) Signed-off-by: Dou Liyang <douly.fnst@cn.fujitsu.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: bp@alien8.de Cc: nicstange@gmail.com Cc: wanpeng.li@hotmail.com Link: http://lkml.kernel.org/r/1488261052-25753-1-git-send-email-douly.fnst@cn.fujitsu.comSigned-off-by: Ingo Molnar <mingo@kernel.org>

Pull IDR rewrite from Matthew Wilcox: "The most significant part of the following is the patch to rewrite the IDR & IDA to be clients of the radix tree. But there's much more, including an enhancement of the IDA to be significantly more space efficient, an IDR & IDA test suite, some improvements to the IDR API (and driver changes to take advantage of those improvements), several improvements to the radix tree test suite and RCU annotations. The IDR & IDA rewrite had a good spin in linux-next and Andrew's tree for most of the last cycle. Coupled with the IDR test suite, I feel pretty confident that any remaining bugs are quite hard to hit. 0-day did a great job of watching my git tree and pointing out problems; as it hit them, I added new test-cases to be sure not to be caught the same way twice" Willy goes on to expand a bit on the IDR rewrite rationale: "The radix tree and the IDR use very similar data structures. Merging the two codebases lets us share the memory allocation pools, and results in a net deletion of 500 lines of code. It also opens up the possibility of exposing more of the features of the radix tree to users of the IDR (and I have some interesting patches along those lines waiting for 4.12) It also shrinks the size of the 'struct idr' from 40 bytes to 24 which will shrink a fair few data structures that embed an IDR" * 'idr-4.11' of git://git.infradead.org/users/willy/linux-dax: (32 commits) radix tree test suite: Add config option for map shift idr: Add missing __rcu annotations radix-tree: Fix __rcu annotations radix-tree: Add rcu_dereference and rcu_assign_pointer calls radix tree test suite: Run iteration tests for longer radix tree test suite: Fix split/join memory leaks radix tree test suite: Fix leaks in regression2.c radix tree test suite: Fix leaky tests radix tree test suite: Enable address sanitizer radix_tree_iter_resume: Fix out of bounds error radix-tree: Store a pointer to the root in each node radix-tree: Chain preallocated nodes through ->parent radix tree test suite: Dial down verbosity with -v radix tree test suite: Introduce kmalloc_verbose idr: Return the deleted entry from idr_remove radix tree test suite: Build separate binaries for some tests ida: Use exceptional entries for small IDAs ida: Move ida_bitmap to a percpu variable Reimplement IDR and IDA using the radix tree radix-tree: Add radix_tree_iter_delete ...

Pull nfsd updates from Bruce Fields: "The nfsd update this round is mainly a lot of miscellaneous cleanups and bugfixes. A couple changes could theoretically break working setups on upgrade. I don't expect complaints in practice, but they seem worth calling out just in case: - NFS security labels are now off by default; a new security_label export flag reenables it per export. But, having them on by default is a disaster, as it generally only makes sense if all your clients and servers have similar enough selinux policies. Thanks to Jason Tibbitts for pointing this out. - NFSv4/UDP support is off. It was never really supported, and the spec explicitly forbids it.

The tegra DRM driver produces a harmless warning when built for NOMMU: drivers/gpu/drm/tegra/gem.c: In function 'tegra_drm_mmap': drivers/gpu/drm/tegra/gem.c:508:12: unused variable 'prot' This is because pgprot_writecombine() on ARM returns a constant and ignores its argument.

According to the spec 'ELF for the ARM Architecture' (IHI 0044E), addends for R_ARM_PREL31 relocations are 31-bit signed quantities, so we need to sign extend the value to 32 bits before it can be used as an offset in the calculation of the relocated value. We have not been bitten by this because these relocations are usually emitted against the start of a section, which means the addends never assume negative values in practice. But it is a bug nonetheless, so fix it. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

VECTORS_BASE displays the exception base address. Now on no-MMU as the exception base address is dynamically estimated, define VECTORS_BASE to the variable holding it. As it is the case, limit VECTORS_BASE constant definition to MMU.

No-MMU dynamic exception base address configuration on CP15 processors. In the case of low vectors, decision based on whether security extensions are enabled & whether remap vectors to RAM CONFIG option is selected. For no-MMU without CP15, current default value of 0x0 is retained.

For MMU configurations, VECTORS_BASE is always 0xffff0000, a macro definition will suffice. For no-MMU, exception base address is dynamically determined in subsequent patches. To preserve bisectability, now make the macro applicable for no-MMU scenario too. Thanks to 0-DAY kernel test infrastructure that found the bisectability issue. This macro will be restricted to MMU case upon dynamically determining exception base address for no-MMU. Once exception address is handled dynamically for no-MMU, VECTORS_BASE can be removed from Kconfig.
