In i7core_probe, when setup of mci for 2nd or later socket failed,
we should cleanup prepared mci for 1st socket or so before "put" of

and i7core_remove.

This is a nasty bug. Since kobject count will be reduced by zero by
edac_mc_del_mc(), and this triggers the kobj release method, the
mci memory will be freed automatically. So, all we have left is ctl_name,
as shown by enabling debug:

[   80.822186] EDAC DEBUG: in drivers/edac/edac_mc_sysfs.c, line at 1020: edac_remove_sysfs_mci_device()  remove_link

Also, kfree(mci) shouldn't happen at the kobj.release, as it happens
when edac_remove_sysfs_mci_device() is called, but the logic is:
	edac_remove_sysfs_mci_device(mci);
	edac_printk(KERN_INFO, EDAC_MC,
		"Removed device %d for %s %s: DEV %s\n", mci->mc_idx,
		mci->mod_name, mci->ctl_name, edac_dev_name(mci));
So, as the edac_printk() needs the mci struct, this generates an OOPS.

A very nasty bug were happening on edac core, due to the way mci objects are
freed. mci memory is freed when kobject count reaches zero, by
edac_mci_control_release(). However, from the logs, this is clearly happening
before the final usage of mci struct:

There are two groups of sysfs attributes: one for rdimm and another
for udimm. Instead of changing dynamically the unique static struct
for handling udimm's, declare two vars and make them constant.

This avoids the risk of having two or more memory controllers, each
needing a different set of attributes.

If the host is slow in reading data or doesn't read data at all,
blocking write calls not only blocked the program that called write()
but the entire guest itself.

To overcome this, let's not block till the host signals it has given
back the virtio ring element we passed it.  Instead, send the buffer to
the host and return to userspace.  This operation then becomes similar
to how non-blocking writes work, so let's use the existing code for this
path as well.

This code change also ensures blocking write calls do get blocked if
there's not enough room in the virtio ring as well as they don't return
-EAGAIN to userspace.

When running make clean, Kbuild doesn't process the .config file, so nothing
