From 1da09c43ce5f4fcd98143feb7d2513fe6fd62848 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 18 Jan 2011 19:56:04 +0900 Subject: sh: pci: Support asynchronous initialization of SH-X3 PCIe channels. SH-X3 controllers all have pretty dire delays needed for PHY wakeup, so we attempt to mitigate the damage by bringing them up asynchronously, simply using the synchronization points for persistent bridge to channel numbering.

It is not understandable/formal method. This patch modify FSI and FSI-codecs to use snd_soc_dai_set_fmt. But FSI can use I2S/PCM and SPDIF format today. It can be selected to I2S/PCM by snd_soc_dai_set_fmt, but can not select SPDIF. So, this patch change FSI platform information to have DAI/SPDIF mode. If platform selects DAI mode (default), FSI-codecs can select I2S/PCM by snd_soc_dai_set_fmt, and if it is SPDIF mode, FSI become SPDIF format.

Sometimes the dynamic linker would seg-fault at start up and this was eventually traced to the handling of a COW fault for a page which was being modified by the linker. If there was no cache aliasing between the kernel and the user page, the page was not flushed, leaving the newly copied data in the D-cache. However when executing instructions from that page, the I-cache is filled directly from external memory, rather than the D-cache, and causing garbage to be executed.

This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.
