Some versions of PWRficient 1682M have an interrupt controller in which the first register in each pair for interrupt sources doesn't always read with the right polarity/sense values. To work around this, keep a software copy of the register instead. Since it's not modified from the mpic itself, it's a feasible solution. Still, keep it under a config option to avoid wasting memory on other platforms. Signed-off-by: NOlof Johansson <olof@lixom.net> Signed-off-by: NPaul Mackerras <paulus@samba.org>

This replaces the binding for flash chips in booting-without-of.txt with an clarified and improved version. It also makes drivers/mtd/maps/physmap_of.c recognize this new binding. Finally it revises the Ebony device tree source to use the new binding as an example.

Some firmwares (such as PlanetCore) only provide a base MAC address, and expect the kernel to set certain bits to generate the addresses for the other ports. As such, MAC addresses are generated that may not correspond to actual hardware.

1. ft_create_node was returning the internal pointer rather than a phandle. 2. ft_find_device_rel was treating a "top" phandle of NULL as an error, rather than as the root of the tree. The old, absolute ft_find_device is removed, and the relative version is renamed to ft_find_device().

Add printout of some SoC error status registers, and dump the SLB contents for those machine check events where it makes sense. Since we can't go about and ioremap registers at machine check time, and we generally want to do as little as possible to print out the information, pre-build a table of the registers to dump and their address in the common PCI config space range.

Currently if you don't specify a match callback for your irq_host it's assumed you match everything. This is a kind of opt-out approach, and turns out to be the exception rather than the rule. So change the semantics to be opt-in, ie. you don't match anything unless you provide a match callback. This in itself isn't very useful, but will allow us to provide a default match implementation in a subsequent patch.

One of the very first things lguest_init() does is a memcpy. On Athlon/Duron/K7 or CyrixIII/VIA-C3 or Geode GX/LX, this tries to use MMX. memcpy -> _mmx_memcpy -> kernel_fpu_begin -> clts -> paravirt_ops.clts But we haven't set paravirt_ops.clts yet, so we do the native version and crash. The simplest solution is to use __memcpy. Thanks to Michael Rasenberger for the bug report.

With the I/O space rewrite by BenH, the legacy_serial serial_dev_init() initcall is now called before I/O space is setup, but it's dependent on it being available. Since there's no way to make dependencies between initcalls, we'll just have to move it to device_initcall(). Yes, it's suboptimal but I'm not aware of any better solution at this time, and it fixes a regression from 2.6.22.

由 Paul Mackerras 提交于
Commit f629307c introduced uses of kernel_termios_to_user_termios_1 and user_termios_to_kernel_termios_1 on all architectures. However, powerpc, s390, avr32 and frv don't currently define those functions since their termios struct didn't need to be changed when the arbitrary baud rate stuff was added, and thus the kernel won't currently build on those architectures. This adds definitions of kernel_termios_to_user_termios_1 and user_termios_to_kernel_termios_1 to include/asm-generic/termios.h which are identical to kernel_termios_to_user_termios and user_termios_to_kernel_termios respectively. The definitions are the same because the "old" termios and "new" termios are in fact the same on these architectures (which are the same ones that use asm-generic/termios.h).
