[PATCH] New machine check handler for x86-64
This adds a new completely rewritten machine check handler for x86-64.
The old one never worked on 2.6.
The new handler has many improvements. It closely follows the Intel and AMD
recommendations on MCE handlers now (the old one had many violations). It handles
unrecoverable errors in user space better now - it will only kill the process now
if possible instead of panicing.
This one is CPU independent now - it should work on any CPU that supports the standard
x86 MCA architecture.
This new handler only logs fatal errors that lead to kernel panic to the console.
Non fatal errors are logged race free into a new (non ring) buffer now
and supplied to the user using a new character device. The old one could
deadlock on console and printk locks. This also separates machine check errors
from real kernel errors better. The new buffer has been also designed to
be easily accessible from external debugging tools: it has a signature
and could be even recovered after reboot. It is not organized as a ring buffer -
this means the first errors are kept unless explicitely cleared.
The new error formats can be parsed using ftp://ftp.suse.com/pub/people/ak/x86-64/mcelog.c
The new character device for it can be created with mknod /dev/mcelog c 10 227
There is a new sysfs interface to configure the machine check handler.
It has a "tolerant" parameter that defines the aggressiveness of the machine check:
0: always panic
1: panic if deadlock possible (e.g. MCE happened in the kernel)
2: try to avoid panic
Default is 2
Despite of having more features the new handler is shorter.

Replace open-coded declarations all over the place. This patch found a
couple of prior bugs. It appears to be more important with -mregparm=3 as we

Some syscalls have arch-dependent arguments, so their prototypes are in the

were already arch-specific syscall prototypes in asm/unistd.h...
Tested on x86, ia64, x86_64, ppc64, s390 and sparc64. May cause
trivial-to-fix build breakage on other architectures.

[PATCH] Clean up IRQ mapping code
On the larger ppc64 machines we remap the interrupt numbers used by
the hardware/firmware to virtual IRQ numbers < NR_IRQS. Up until now
we have used an array for the "real" (hardware) -> virtual IRQ number
mapping, but with new machines coming out that will have 24-bit
hardware IRQ numbers, this will break. However, in fact it is only
the XICS interrupt controller which cares about this mapping. This
patch moves that side of the mapping (real -> virtual) into the XICS
code and makes it use a radix tree.
On iSeries we have a similar issue, where the "real" IRQ numbers that
we need are in fact an encoding of the bus/device/function address of
the device. This patch fixes iSeries to use the virt->real IRQ
mapping, allowing us to support larger iSeries machines. This patch
also gets rid of the temporary hack that Stephen Rothwell submitted.
On machines with OpenPIC (including the G5) the mapping is explicitly
1-1, and that hasn't changed. For other machines this patch cleans up
and simplifies the code that sets up the virtual->real mapping.
I have tested this code and verified that G5, pSeries and iSeries boot
and run correctly with this patch.
