2006-10-07[PATCH] m68k pt_regs fixesAl Viro
m68k_handle_int() split in two functions: __m68k_handle_int() takes pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs *. Places where we used to call m68k_handle_int() recursively with the same pt_regs have simply lost the second argument, the rest is switched to __m68k_handle_int(). The rest of patch is just dropping pt_regs * where needed. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-10-06[POWERPC] Minor fix for bootargs propertyGeoff Levand
Avoid the use of an uninitialized stack variable when the powerpc device tree bootargs property is either missing or incorrectly defined. This also makes CONFIG_CMDLINE work properly under these conditions. This change adds a test for the existence of the bootargs property. early_init_dt_scan_chosen() tests for a zero length bootargs property in its CONFIG_CMDLINE processing, but the current implementation of of_get_flat_dt_prop() doesn't assign a value to the length when no property is found. Since an automatic variable is used, a stale value from the stack will be used in the test. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-10-06[POWERPC] Don't get PCI IRQ from OF for devices with no IRQBenjamin Herrenschmidt
This patch adds checking of the PCI_INTERRUPT_PIN register before using standard OF parsing to retreive PCI interrupts. The reason is that some PCI devices may have no PCI interrupt, though they may have interrupts attached via other means. In this case, we shall not use irq->pdev, but device-specific code can later retreive those interrupts instead. Without that patch, Maple and derivatives don't get the right interrupt for the second IDE channel as the linux IDE code fallsback to the PCI irq instead of trying to use the legacy ones for the on-board controller (which has no PCI_INTERRUPT_PIN). Having no PCI IRQ assign to it (as it doesn't request any) fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-10-06[POWERPC] Fix zImage decompress locationBenjamin Herrenschmidt
The zImage wrapper has a "hack" that force the decompression to happen above 20Mb for 64 bits kernels, to work around issues with some firmwares on the field. However, the new wrapper has a bug which makes that hack not work properly. This fixes it.

2006-10-06[POWERPC] linux,tce-size property is 32 bitsNathan Lynch
The "linux,tce-size" property is only 32 bits (see prom_initialize_tce_table() in arch/powerpc/kernel/prom_init.c). Treating it as an unsigned long in iommu_table_setparms() leads to access beyond the end of the property's buffer, so we pass garbage to the memset() in that function.

2006-10-05[PATCH] x86-64: Calgary IOMMU: Fix off by one when calculating register ↵Jon Mason
space location The purpose of the code being modified is to determine the location of the calgary chip address space. This is done by a magical formula of FE0MB-8MB*OneBasedChassisNumber+1MB*(RioNodeId-ChassisBase) to find the offset where BIOS puts it. In this formula, OneBasedChassisNumber corresponds to the NUMA node, and rionodeid is always 2 or 3 depending on which chip in the system it is. The problem was that we had an off by one error that caused us to account some busses to the wrong chip and thus give them the wrong address space. Fixes RH bugzilla #203971.

2006-10-05[PATCH] x86-64: Calgary IOMMU: deobfuscate calgary_initJon Mason
calgary_init's for loop does not correspond to the actual device being checked, which makes its upperbound check for array overflow useless. Changing this to a do-while loop is the correct way of doing this. There should be no possibility of spinning forever in this loop, as pci_get_device states that it will go through all iterations, then return NULL (thus breaking the loop).
