ASoC: CX20442: fix wrong reg_cache_default content

Content of the CX20442's snd_soc_codec_driver.reg_cache_default pointed
area, introduced with my recent NULL pointer dereferece fix (commit
f019ee5feb344ff0b22b58df4568676295aae14f), occured wrong after further
testing, more thorough than just booting successfully. There are two
problems with it:

1) It should read
(1 << CX20442_TELOUT) | (1 << CX20442_MIC),
   not
CX20442_TELOUT | CX20442_MIC.

2) While correctly matching actual codec hardware state on boot when
   fixed per 1), a few more code modifications would still be required
   to reflect that state not only into register cache, but also force
   them into DAPM pins state, otherwise an inconsitency occures which
   may prevent further codec state changes from being applied correctly.
   As a result, the phone stops ringing after reboot, until someone
   picks up the handset for the first time.

Revert that reg_cache_default content to a working, previous de facto
default value of 0, in hope this change can still be accepted as an rc
cycle fix.

Starting from perf_event_alloc()->perf_init_event(), the kernel
assumes that event->cpu is either -1 or the valid CPU number.

Change perf_event_alloc() to validate this argument early. This
also means we can remove the similar check in

8 years agoMIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs
Gabor Juhos [Tue, 4 Jan 2011 20:28:14 +0000]
MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs

This patch adds initial support for various Atheros SoCs based on the
MIPS 24Kc core. The following models are supported at the moment:

  - AR7130
  - AR7141
  - AR7161
  - AR9130
  - AR9132
  - AR7240
  - AR7241
  - AR7242

The current patch contains minimal support only, but the resulting
kernel can boot into user-space with using of an initramfs image on
various boards which are using these SoCs. Support for more built-in
devices and individual boards will be implemented in further patches.

David Daney [Tue, 28 Dec 2010 02:18:29 +0000]
MIPS: Use WARN() in uasm for better diagnostics.

On the off chance that uasm ever warns about overflow, there is no way
to know what the offending instruction is.

Change the printks to WARNs, so we can get a nice stack trace.  It has
the added benefit of being much more noticeable than the short single
line warning message, so is less likely to be ignored.

This patch adds a generic solution to support multiple machines based on
a given SoC within a single kernel image. It is implemented already for
several other architectures but MIPS has no generic support for that yet.

[Ralf: This competes with DT but DT is a much more complex solution and this
code has been used by OpenWRT for a long time so for now DT is a bad reason
to stop the merge but longer term this should be migrated to DT.]

perf: Fix contexted inheritance

Linus reported that the RCU lockdep annotation bits triggered for this
rcu_dereference() because we're not holding rcu_read_lock().

Going over the code I cannot convince myself its correct:

 - holding a ref on the parent_ctx, doesn't avoid it being uncloned
   concurrently (as the comment says), so we can race with a free.

 - holding parent_ctx->mutex doesn't avoid the above free from taking
   place either, it would at best avoid parent_ctx from being freed.

I.e. the warning is correct. To fix the bug, serialize against the
unclone_ctx() call by extending the reach of the parent_ctx->lock.

x86: Make relocatable kernel work with new binutils

The CONFIG_RELOCATABLE=y option is broken with new binutils, which will make
boot panic.

According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to
2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is
using such binutils. See:

    http://sourceware.org/bugzilla/show_bug.cgi?id=12327

The reason of the boot panic is that we have 'jiffies = jiffies_64;' in
vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is
warning saying jiffies is an absolute address and can't be relocatable. At
runtime, jiffies will have virtual address 0.

8 years agoautofs4: split autofs4_init_ino()

autofs4: split autofs4_init_ino()

split init_ino into new_ino and clean_ino; the former is
what used to be init_ino(NULL, sbi), the latter is for cases
where we passed non-NULL ino.  Lose unused arguments.

autofs4: mkdir and symlink always get a dentry that had passed lookup

... so ->d_fsdata will have been set up before we get there

autofs4: kill ->size in autofs_info

It's used only to pass the length of symlink body to
autofs4_get_inode() in autofs4_dir_symlink().  We can
bloody well set inode->i_size in autofs4_dir_symlink()
directly and be done with that.
