* v4l1: fix 32-bit compat microcode loading translationLinus Torvalds2010-10-15
| | | | | | | | | | | | | | | | | | | The compat code for the VIDIOCSMICROCODE ioctl is totally buggered. It's only used by the VIDEO_STRADIS driver, and that one is scheduled to staging and eventually removed unless somebody steps up to maintain it (at which point it should use request_firmware() rather than some magic ioctl). So we'll get rid of it eventually. But in the meantime, the compatibility ioctl code is broken, and this tries to get it to at least limp along (even if Mauro suggested just deleting it entirely, which may be the right thing to do - I don't think the compatibility translation code has ever worked unless you were very lucky).

This patch fixes this regression by trivially bringing back that part of mmc_suspend_host(), which was removed by 4c2ef25fe0b.

This switch does not present the usual register interface of a PHY, it presents nothing. So a PHY scan will find nothing - it finds ID's of 0 for each PHY on the attached MII bus. After the FEC driver was changed to use phylib for supporting PHYs it no longer works on this particular board/switch setup. Add code support to use a fixed phy if no PHY is found on the MII bus. This is based on the way the cpmac.c driver solved this same problem. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: David S. Miller <davem@davemloft.net>

It inadvertently exported an internal helper function ioat_tx_status() instead of ioat_dma_tx_status(). The latter polls the hardware to get the latest completion state, while the helper just evaluates the current state without touching hardware. The effect is that we end up waiting for completion timeouts or descriptor allocation errors before the completion state is updated. iperf (before fix): [SUM] 0.0-41.3 sec 364 MBytes 73.9 Mbits/sec iperf (after fix): [SUM] 0.0- 4.5 sec 499 MBytes 940 Mbits/sec This is a regression starting with 2.6.35.

However if during driver initialisation we were unable aquire linkage to the i915 driver enabling GPU turbo will lead to an oops on the first attempt to determine GPU busy status. Ensure that we do not enable GPU turbo unless we have driver linkage.

Without this change, it is possible that ips->adjust is NULL when kthread_stop() or wake_up_process() is called in ips_monitor().

The rcvmsg struct comes from the memcpy_fromio() in receivemessage(). I guess that means it's data off the wire. I'm not very familiar with this code but I don't see any reason to assume these strings are NULL terminated. Also it's weird that "dn" in a 50 character buffer but we only seem to use 32 characters. In drivers/isdn/sc/scioc.h, "dn" is only a 49 character buffer. So potentially there is still an issue there. The important thing for now is to prevent the memory corruption.
