ASoC: ics43432: Add codec driver for InvenSense ICS-43432

Add support for the InvenSense ICS-43432 I2S MEMS microphone.

This is a non-software-configurable MEMS microphone with I2S output.

Tested on a setup with a single ICS-43432 (the device itself supports
stereo operation using a hardware pin controlling left vs. right channel
output).

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.

x86/fpu/math-emu: Fix math-emu boot crash

On a math-emu bootup the following crash occurs:

Initializing CPU#0
------------[ cut here ]------------
kernel BUG at arch/x86/kernel/traps.c:779!

The reason is that in the following commit:

  b1276c48e91b ("x86/fpu: Initialize fpregs in fpu__init_cpu_generic()")

I failed to consider math-emu's limitation that it cannot execute the
FNINIT instruction in kernel mode.

The long term fix might be to allow math-emu to execute (certain) kernel
mode FPU instructions, but for now apply the safe (albeit somewhat ugly)
fix: initialize the emulation state explicitly without trapping out to
the FPU emulator.

9 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).

9 years agox86/idle: Restore trace_cpu_idle to mwait_idle() calls

x86/idle: Restore trace_cpu_idle to mwait_idle() calls

Commit b253149b843f ("sched/idle/x86: Restore mwait_idle() to fix boot
hangs, to improve power savings and to improve performance") restores
mwait_idle(), but the trace_cpu_idle related calls are missing. This
causes powertop on my old desktop powered by Intel Core2 E6550 to
report zero wakeups and zero events.

Add them back to restore the proper behaviour.
