commit 47251b4d960bdfa648b0d06dbc6d445f41cb3906 have changed the logic for unexplained reasons.

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 [ 80.832590] EDAC DEBUG: in drivers/edac/edac_mc_sysfs.c, line at 1024: edac_remove_sysfs_mci_device() remove_mci_instance [ 80.843776] EDAC DEBUG: in drivers/edac/edac_mc_sysfs.c, line at 640: edac_mci_control_release() mci instance idx=0 releasing [ 80.855163] EDAC MC: Removed device 0 for i7core_edac.c i7 core #0: DEV 0000:3f:03.0 [ 80.862936] EDAC DEBUG: in drivers/edac/i7core_edac.c, line at 2089: (null): free structs [ 80.871134] EDAC DEBUG: in drivers/edac/edac_mc.c, line at 238: edac_mc_free() [ 80.878379] EDAC DEBUG: in drivers/edac/edac_mc_sysfs.c, line at 726: edac_mc_unregister_sysfs_main_kobj() [ 80.888043] EDAC DEBUG: in drivers/edac/i7core_edac.c, line at 1232: drivers/edac/i7core_edac.c: i7core_put_devices() 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().

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. While here, use const on all places where it is applicable.

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 generates a platform-y variable. We can get it to descend into the platform directories by setting $(obj-). The dec Platform file was unconditionally setting platform-, obliterating its previous contents and preventing some directories from being cleaned.

This patch reverts the driver to enabling/disabling the NFC interrupt mask rather than enabling/disabling the system interrupt. This cleans up the driver so that it doesn't rely on interrupts being disabled within the interrupt handler. For i.MX21 we keep the current behaviour, that is calling enable_irq/disable_irq_nosync to enable/disable interrupts. This patch is based on earlier work by John Ogness.
