2006-04-21[PARISC] Further work for multiple page sizesHelge Deller
More work towards supporing multiple page sizes on 64-bit. Convert some assumptions that 64bit uses 3 level page tables into testing PT_NLEVELS. Also some BUG() to BUG_ON() conversions and some cleanups to assembler. Signed-off-by: Helge Deller <deller@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2006-04-21[PARISC] Document that we tolerate "Relaxed Ordering"Grant Grundler
This means "DMA Read returns" can bypass "MMIO Writes". Violating the PCI specs in this case improves outbound DMA "flows" and is currently not required by any drivers. This is NOT a new behavior. Previous chipsets did this already and I believe ZX1 PDC was already setting this for hpux. I just want to further document the behavior.

2006-04-21[IA64] Setup an IA64 specific reclaim distanceChristoph Lameter
RECLAIM_DISTANCE is checked on bootup against the SLIT table distances. Zone reclaim is important for system that have higher latencies but not for systems that have multiple nodes on one motherboard and therefore low latencies. We found that on motherboard latencies are typically 1 to 1.4 of local memory access speed whereas multinode systems which benefit from zone reclaim have usually more than 1.5 times the latency of a local access. Set the reclaim distance for IA64 to 1.5 times. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2006-04-21[PATCH] powermac: Fix i2c on keywest based chipsBenjamin Herrenschmidt
The new i2c implementation for PowerMac has a regression that causes the hardware to go out of state when probing non-existent devices.

2006-04-21[PATCH] powerpc: Lower threshold for DART enablement to 1GBOlof Johansson
Turn on the DART already at 1GB. This is needed because of crippled devices in some systems, i.e. Airport Extreme cards, only supporting 30-bit DMA addresses. Otherwise, users with between 1 and 2GB of memory will need to manually enable it with iommu=force, and that's no good. Some simple performance tests show that there's a slight impact of enabling DART, but it's in the 1-3% range (kernel build with disk I/O as well as over NFS). iommu=off can still be used for those who don't want to deal with the overhead (and don't need it for any devices).

for_each_cpu() actually iterates across all possible CPUs.

2006-04-20[PATCH] i386/x86-64: Fix x87 information leak between processesAndi Kleen
AMD K7/K8 CPUs only save/restore the FOP/FIP/FDP x87 registers in FXSAVE when an exception is pending. This means the value leak through context switches and allow processes to observe some x87 instruction state of other processes. This was actually documented by AMD, but nobody recognized it as being different from Intel before. The fix first adds an optimization: instead of unconditionally calling FNCLEX after each FXSAVE test if ES is pending and skip it when not needed. Then do a x87 load from a kernel variable to clear FOP/FIP/FDP. This means other processes always will only see a constant value defined by the kernel in their FP state. I took some pain to make sure to chose a variable that's already in L1 during context switch to make the overhead of this low. Also alternative() is used to patch away the new code on CPUs who don't need it. Patch for both i386/x86-64. The problem was discovered originally by Jan Beulich. Richard Brunner provided the basic code for the workarounds, with contribution from Jan.

2006-04-20[PATCH] sound: fix hang in mpu401_uart.cJon Masters
This fixes a hang in mpu401_uart.c that can occur when the mpu401 interface is non-existent or otherwise doesn't respond to commands but we issue IO anyway. snd_mpu401_uart_cmd now returns an error code that is passed up the stack so that an open() will fail immediately in such cases. Eventually discovered after wine/cxoffice would constantly cause hard lockups on my desktop immediately after loading (emulating Windows too well). Turned out that I'd recently moved my sound cards around and using /dev/sequencer now talks to a sound card with a broken MPU. This second version changes -EFAULT to -EIO and frees open resources on error too. Test booted and seems to work ok.
