module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Acked-by: Mauro Carvalho Chehab

Several fields in struct cpuinfo_x86 were not defined for the
!SMP case, likely to save space. However, those fields still
have some meaning for UP, and keeping them allows some #ifdef
removal from other files. The additional size of the UP kernel
from this change is not significant enough to worry about
keeping up the distinction:text data bss dec hex filename

The edac driver for Sandy Bridge was found to be reporting "FPM"
for edac_mode, which clearly doesn't make sense. It was found that
sb_edac.c:get_dimm_config was reusing a variable for both mem_type
and edac_type, and thus was overwriting the value after setting
it correctly. This patch fixes that issue.Before the patch:

This driver is known to work on mine and Tony's test environments,
using software error injection, and a partial hardware/software
error injection tool.There's no broader range test yet to double check if the error decoding
logic will actually point to the right DIMM, so use it with care.
More tests are required to be sure that the driver will work on all
different types of memory configurations.If you're willing to risk using it, I suggest you to enable EDAC debugs
for your test machines, as the debug logs helps to track what's going
inside the driver.Please feed me with bug reports, if you notice that the driver
is miss-behaving.Tested-by: Tony Luck

Nehalem-EX uses a different memory controller. However, as the
memory controller is not visible on some Nehalem/Nehalem-EP, we
need to indirectly probe via a X58 PCI device. The same devices
are found on (some) Nehalem-EX. So, on those machines, the
probe routine needs to return -ENODEV, as the actual Memory
Controller registers won't be detected.Signed-off-by: Mauro Carvalho Chehab

mce->socketid and cpu_data(mce->cpu).phys_proc_id are the same,
compare with mce_setup (in mce.c):
m->cpu = m->extcpu = smp_processor_id();

m->socketid = cpu_data(m->extcpu).phys_proc_id;This makes it easier for example for XEN patches to hook into
the MCE subsystem.
