Charles Keepax [Tue, 25 Aug 2015 11:43:48 +0000 (12:43 +0100)]
ASoC: arizona: Poll for FLL clock OK rather than use interrupts

The extcon driver takes the DAPM mutex from within the interrupt thread
in several places, which makes it possible to get into a situation where
the interrupt thread is blocked waiting on the DAPM mutex whilst a DAPM
sequence is running which is attempting to configure the FLL. In this
case the FLL completion can't be completed as as the IRQ handler is
ONE_SHOT, which cause the FLL lock to use the full time out (250mS) and
report that the process timed out.

It is not really practical to make the extcon driver not take the DAPM
mutex from within the interrupt thread, at least not without extensive
modification. So this patch fixes the issue by switching the wait for
the FLL lock to polling. A few fast polls are done first as the FLL
should lock quickly for a good quality reference clock, (indeed it hits
on the first poll on my system) and it will poll every 20mS after that
until it times out.

soft math state.

With this fix applied math-emu kernels boot up fine on modern
hardware and the 'no387 nofxsr' boot options.

The long term fix might be to allow math-emu to execute (certain) kernel

8 years agomm: make page pfmemalloc check more robust
Michal Hocko [Fri, 21 Aug 2015 21:11:51 +0000 (14:11 -0700)]
mm: make page pfmemalloc check more robust

Commit c48a11c7ad26 ("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).

Since commit feb44f1f7a4ac299d1ab1c3606860e70b9b89d69 (x86/xen:
Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need
a full APIC driver and thus should depend on X86_LOCAL_APIC.

This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by
disabling Xen support in this configuration.

Users needing Xen support in a non-SMP i386 kernel will need to enable
CONFIG_X86_UP_APIC.

Restore the correct behaviour by removing the irq_set_type callback

The conversion of the crossbar irqchip to hierarchical irq domains

As the flag is not set the masking of the non-wakeup irqs is not

PCI: Tolerate hierarchies with no Root Port

We should not assume any particular hardware topology.  Commit d0751b98dfa3
("PCI: Add dev->has_secondary_link to track downstream PCIe links") relied
on the assumption that every PCIe hierarchy is rooted at a Root Port.  But
we can't rely on any assumption about what hardware we will find; we just
have to deal with the world as it is.

On some platforms, PCIe devices (endpoints, switch upstream ports, etc.)
appear directly on the root bus, and there is no Root Port in the PCI bus
hierarchy.  For example, Meelis observed these top-level devices on a
Sparc V245:

  0000:02:00.0 PCI bridge to [bus 03-0d]    Switch Upstream Port
  0001:02:00.0 PCI bridge to [bus 03]       PCIe to PCI/PCI-X Bridge

These devices *look* like they have links going upstream, but there really
are no upstream devices.

In set_pcie_port_type(), we used the parent device to figure out which side
of a switch port has a link, so if the parent device did not exist, we
dereferenced a NULL parent pointer.

Check whether the parent device exists before dereferencing it.

Meelis observed this oops on Sparc V245 and T2000.  Ben Herrenschmidt says
this is also possible on IBM PowerVM guests on PowerPC.
