When we have an ISA memory hole (ie, a PCI window that allows us to generate PCI memory cycles at low PCI address) mixed with other resources using a different CPU <=> PCI mapping, we must not keep the ISA hole in the bridge resource list. If we do, things might start trying to allocate device resources in there and will get the PCI addresses wrong. This fixes it by arranging to remove the ISA memory hole resource in this case. This fixes various cases of PCMCIA breakage on PowerBooks using the MPC106 "grackle" bridge.

The kernel copy of the rtas args struct contains the return value(s) for the specified rtas call. These are copied back to user space with the assumption that every value has been set by the rtas call, which turns out to be not always true. Thus userspace can see random values and think the call failed when in fact it succeeded, but for some reason didn't set one of the return values. This fixes the problem by zeroing out the return value fields of the rtas args struct before processing the rtas call.

2.6.26 corrected the mutex locking on tty resizing to fix the case where you could get the tty/vt sizing out of sync. That turns out to have a deadlock. The actual fix is really major and I've got it lined up as part of the ops changes for 2.6.28 so for 2.6.26/2.6.27 it is safer to reintroduce this ages old minor bug.

When I tested the same on older kernels like 2.6.18, I got the correct result i.e errno 12 (ENOMEM). I think in source code mlock(2), setting errno ENOMEM has been missed in do_mlock() , on mlock_fixup() failure. SUSv3 requires the following behavior frmo mlock(2). [ENOMEM] Some or all of the address range specified by the addr and len arguments does not correspond to valid mapped pages in the address space of the process. [EAGAIN] Some or all of the memory identified by the operation could not be locked when the call was made. This rule isn't so nice and slighly strange. but many people think POSIX/SUS compliance is important.

For some time my at91sam9260 board with JFFS2 on serial flash (m25p80) would hang when accessing the serial flash and SPI bus. Slowing the SPI clock down to 9 MHz reduced the occurrence of the hang from "always" during boot to a nuisance level that allowed other SW development to continue. Finally had to address this issue when an application stresses the I/O to always cause a hang. Hang seems to be caused by a missed SPI interrupt, so that the task ends up waiting forever after calling spi_sync(). The fix has 2 parts. First is to halt the DMA engine before the "current" PDC registers are loaded. This ensures that the "next" registers are loaded before the DMA operation takes off. The second part of the fix is a kludge that adds a "completion" interrupt in case the ENDRX interrupt for the last segment of the DMA chaining operation was missed. The patch allows the SPI clock for the serial flash to be increased from 9 MHz to 15 MHz (or more?). No hangs or SPI overruns were encountered. Haavard: while this patch does indeed improve things, I still see overruns and CRC errors on my NGW100 board when running the DataFlash at 10 MHz. However, I think some improvement is better than nothing, so I'm passing this on for inclusion in 2.6.27.
