2010-03-12ipconfig: Handle devices which take some time to come up.David S. Miller
Some network devices, particularly USB ones, take several seconds to fully init and appear in the device list. If the user turned ipconfig on, they are using it for NFS root or some other early booting purpose. So it makes no sense to just flat out fail immediately if the device isn't found. It also doesn't make sense to just jack up the initial wait to something crazy like 10 seconds. Instead, poll immediately, and then periodically once a second, waiting for a usable device to appear. Fail after 12 seconds. Signed-off-by: David S. Miller <davem@davemloft.net> Tested-by: Christian Pellegrin <chripell@fsfe.org>
2010-03-11OMAP4: fix temporary hacks that break multi-omap PMKevin Hilman
When building for multi-omap, and OMAP4 is enabled, CONFIG_ARCH_OMAP4 will be true and prevent included code from building/running for OMAP2/3 as well. This problem exists in io.c where some hwmod/PM/SDRC init code is prevented from running even on OMAP2/3 when OMAP4 is included in a multi-OMAP build. A quick glance suggests that this #ifndef is no longer needed in most of the cases. In the remaining cases, the function is wrapped with "if (cpu_is_omap24xx() || cpu_is_omap34xx())" which will be optimized out for OMAP4-only builds. Note that this is only a short-term fix. Longer-term, OMAP4 needs to create init functions for SDRC and hwmod late-init.

2010-03-11OMAP2: cpu_is_omap2*: fix compile-time removal of unused codeKevin Hilman
Currently if omap2420 is defined but not omap2430, cpu_is_omap2430() is still defined as a macro, instead of #define'd to zero. This results in conditional cpu_is_omap2430() code still being compiled, and leads to possible compile/link errors. In particular for hwmod init. To fix, add extra #ifdefs to CPU check macros to ensure that the is_omap* macros are zero for each OMAP2 if they are not configured into the kernel.

2010-03-11omap: pass the reboot command to the boot loaderAaro Koskinen
This patch follows the commit be093beb608edf821b45fe00a8a080fb5c6ed4af by Russell King: OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). The patch adds the missing parameter to omap1_arch_reset() and omap_prcm_arch_reset(), and modifies the latter to pass the reboot command parameter to the boot loader instead of reboot mode (which is for kernel internal use only and cannot be modified by the userspace).

2010-03-11IPoIB: Fix TX queue lockup with mixed UD/CM trafficEli Cohen
The IPoIB UD QP reports send completions to priv->send_cq, which is usually left unarmed; it only gets armed when the number of outstanding send requests reaches the size of the TX queue. This arming is done only in the send path for the UD QP. However, when sending CM packets, the net queue may be stopped for the same reasons but no measures are taken to recover the UD path from a lockup. Consider this scenario: a host sends high rate of both CM and UD packets, with a TX queue length of N. If at some time the number of outstanding UD packets is more than N/2 and the overall outstanding packets is N-1, and CM sends a packet (making the number of outstanding sends equal N), the TX queue will be stopped. When all the CM packets complete, the number of outstanding packets will still be higher than N/2 so the TX queue will not be restarted. Fix this by calling ib_req_notify_cq() when the queue is stopped in the CM path. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2010-03-11omap2: Update n8x0 defconfig to test multi-omap and DMA api changesTony Lindgren
Recent DMA API changes broke compile for tusb6010. While testing the fixes for tusb6010, I had to update the n8x0 defconfig quite a bit. Might as well merge it while at it to make it more usable as we're using this to test the multi-omap booting between V6 and V7 ARMs. Also, anybody using n8x0 with a current kernel will most likely want to mount root on the MMC instead of the onenand to keep the Maemo install intact.

Now, in our RR example, n_running == 0 because we fully unscheduled, so event-50 will retain its idx==32, even though in scheduling it will have gotten idx=0, and we don't trigger the re-assign path. The easiest way to fix this is the below patch, which simply validates the full assignment in the second pass.

2010-03-11perf: Make the install relative to DESTDIR if specifiedJohn Kacur
Without this change, the install path is relative to prefix/DESTDIR where prefix is automatically set to $HOME. This can produce unexpected results. For example: make -C tools/perf DESTDIR=/home/jkacur/tmp install-man creates the directory: /home/jkacur/home/jkacur/tmp/share/... instead of the expected: /home/jkacur/tmp/share/...
