there can result quite a bit of extra cross CPU traffic as soon as

xend: Do not mess with bridge if admin has set one up already
Previously, the default "network-script",
/etc/xen/scripts/network-bridge, would attempt to do its horrid work
even if you had already set everything up in /etc/network/interfaces.
Setting up your bridge in /etc/network/interfaces is:
* easy
* required for libxl since libxl never does it for you
* not a fragile piece of lunacy
* properly documented
* the way everyone would expect it to work
In this small patch we make it so that the default config for xend
doesn't mess about on startup if you already have a bridge, and
doesn't mess about on shutdown unless your first-named bridge (eth0 or
xenbr0, normally) doesn't also have a physical interface named
p<whatever> (peth0 or pxenbr0) enslaved to it. The latter test is not
ideal but will hopefully do from now until the time xend finally dies.

Originally mce_action is called for delayed hander. Change it to be

Change the return value to be more clearly.
Change the mca handler from mca_code to a function to be more

mce: Clean-up mcheck_init handler
Firstly and most importantly, the maxium MCA banks are hard-coded as
MAX_NR_BANKS, which is 30. This is not architecture correct. This
patch removes this definition, replacig the cpu_banks_t with
mca_banks, and provide some basic function, like
set/clear/test/alloc/free for mcabanks_t.
Secondly, remove the broadcast_check code to intel specific, since
only Intel platform support broadcast now.
Thirdly, the X86_FEATURE_MCA check and CR4_MCE enable is done in every
vendor-specifc callback, that's redundant, move it to
mcheck_init. Also, we should enable CR4_MCE only in the end of the
mcheck_init, to close the small window between CR4_enable and the mca
setup.
And we also move vmce specific code to vmce.c as vmce_init, to make
code clean.
