* [PATCH] arm: fix IXP4xx flash resource rangeDeepak Saxena2005-08-26
| | | | | | | | | | | | | We are currently reserving one byte more than actually needed by the flash device and overlapping into the next I/O expansion bus window. This a) causes us to allocate an extra page of VM due to ARM ioremap() alignment code and b) could cause problems if another driver tries to request the next expansion bus window.

* [PATCH] x86_64: Tell VM about holes in nodesAndi Kleen2005-08-26
| | | | | | | | | | | | | | | | | | | | | | | Some nodes can have large holes on x86-64. This fixes problems with the VM allowing too many dirty pages because it overestimates the number of available RAM in a node. In extreme cases you can end up with all RAM filled with dirty pages which can lead to deadlocks and other nasty behaviour. This patch just tells the VM about the known holes from e820. Reserved (like the kernel text or mem_map) is still not taken into account, but that should be only a few percent error now. Small detail is that the flat setup uses the NUMA free_area_init_node() now too because it offers more flexibility.

* [PATCH] ppc64: Export machine_power_off for therm_pm72 moduleBenjamin Herrenschmidt2005-08-24
| | | | | | | | | | | This patch puts back the export of machine_power_off() that was removed by some janitor as it's used for emergency shutdown by the G5 thermal control driver. Wether that driver should use kernel_power_off() instead is debatable and a post-2.6.13 decision. In the meantime, please commit that patch that fixes the driver for now.

* [PATCH] x86_64: Don't oops at boot when empty Opteron node has IOAndi Kleen2005-08-23
| | | | | | | | | | | | | The code to detect IO links on Opteron would not check if the node had actually memory. This could lead to pci_bus_to_node returning an invalid node, which might cause crashes later when dma_alloc_coherent passes it to page_alloc_node(). The bug has been there forever but for some reason it is causing now crashes. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] i386: fix incorrect FP signal codeChuck Ebbert2005-08-23
| | | | | | | | | | | | | | | i386 floating-point exception handling has a bug that can cause error code 0 to be sent instead of the proper code during signal delivery. This is caused by unconditionally checking the IS and c1 bits from the FPU status word when they are not always relevant. The IS bit tells whether an exception is a stack fault and is only relevant when the exception is IE (invalid operation.) The C1 bit determines whether a stack fault is overflow or underflow and is only relevant when IS and IE are set.

| | | | | | | | | | | | Thanks to Stephane, we've now worked out the real cause of the `Linux will not boot on simulator' problem.

| | | | | | | | | | | | | | | | | | | | | | The main issue is that bus_fixup calls may potentially call functions that require a valid bus->sysdata pointer.
