All IRQs except for IRQ 0 seem to not need acking, so drop acking for them. The ENMI needs to have the ack done *after* clearing the interrupt source, otherwise we will get a spurious interrupt for each real interrupt. So use the new IRQCHIP_EOI_THREADED flag for this in combination with handle_fasteoi_irq. This uses a separate irq_chip struct for IRQ 0, since we only want this behavior for IRQ 0.

SUN4I_IRQ_VECTOR_REG containing 0 can mean one of 3 things: 1) no more irqs pending 2) irq 0 pending 3) spurious irq So if we immediately get a reading of 0, check the irq-pending reg to differentiate between 2 and 3. We only do this once to avoid the extra check in the common case of 1) hapening after having read the vector-reg once.

The flag is necessary for interrupt chips which require an ACK/EOI after the handler has run. In case of threaded handlers this needs to happen after the threaded handler has completed before the unmask of the interrupt. The flag is only unseful in combination with the handle_fasteoi_irq flow control handler. It can be combined with the flag IRQCHIP_EOI_IF_HANDLED, so the EOI is not issued when the interrupt is disabled or in progress.

For certain irq types, e.g. gpios, it's necessary to request resources before starting up the irq. This might fail so we cannot use the irq_startup() callback because we might call the irq_set_type() callback before that which does not make sense when the resource is not available. Calling irq_startup() before irq_set_type() can lead to spurious interrupts which is not desired either.

This fixes CVE-2014-0102. The following command sequence produces an oops: keyctl new_session i=`keyctl newring _ses @s` keyctl link @s $i The problem is that search_nested_keyrings() sees two keyrings that have matching type and description, so keyring_compare_object() returns true. s_n_k() then passes the key to the iterator function - keyring_detect_cycle_iterator() - which *should* check to see whether this is the keyring of interest, not just one with the same name. Because assoc_array_find() will return one and only one match, I assumed that the iterator function would only see an exact match or never be called - but the iterator isn't only called from assoc_array_find()... The oops looks something like this: kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003! invalid opcode: 0000 [#1] SMP ... RIP: keyring_detect_cycle_iterator+0xe/0x1f ...

A testcase has been included in the keyutils testsuite for this: http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=891f3365d07f1996778ade0e3428f01878a1790bReported-by: NTommi Rantala <tt.rantala@gmail.com> Signed-off-by: NDavid Howells <dhowells@redhat.com> Acked-by: NJames Morris <james.l.morris@oracle.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

From Kieran Clancy. - If the ACPI sleep control and status registers are not present (which happens if the Hardware Reduced ACPI mode bit is set in the ACPI tables, but also may result from BIOS bugs), we should not try to use ACPI to power off the system and ACPI S5 should not be listed as supported.

It's an enum, not a #define, you can't use it in asm files. Introduced in commit 5fa10196 ("x86: Ignore NMIs that come in during early boot"), and sadly I didn't compile-test things like I should have before pushing out. My weak excuse is that the x86 tree generally doesn't introduce stupid things like this (and the ARM pull afterwards doesn't cause me to do a compile-test either, since I don't cross-compile).

Pull ARM fixes from Russell King: "A number of ARM updates for -rc, covering mostly ARM specific code, but with one change to modpost.c to allow Thumb section mismatches to be detected. ARM changes include reporting when an attempt is made to boot a LPAE kernel on hardware which does not support LPAE, rather than just being silent about it. A number of other minor fixes are included too" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: 7992/1: boot: compressed: ignore bswapsdi2.S ARM: 7991/1: sa1100: fix compile problem on Collie ARM: fix noMMU kallsyms symbol filtering ARM: 7980/1: kernel: improve error message when LPAE config doesn't match CPU ARM: 7964/1: Detect section mismatches in thumb relocations ARM: 7963/1: mm: report both sections from PMD

Pull x86 fixes from Peter Anvin: "A small collection of minor fixes. The FPU stuff is still pending, I fear. I haven't heard anything from Suresh so I suspect I'm going to have to dig into the init specifics myself and fix up the patchset" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86: Ignore NMIs that come in during early boot x86, trace: Further robustify CR2 handling vs tracing x86, trace: Fix CR2 corruption when tracing page faults x86/efi: Quirk out SGI UV
