usbcore: make hcd_endpoint_disable wait for queue to drain

The inconsistent lock state problem in usbcore (the one that shows up
when an HCD is unloaded) comes down to two inter-related problems:

usb_rh_urb_dequeue() isn't set up to be called with interrupts
disabled.

hcd_endpoint_disable() doesn't wait for all URBs on the
endpoint's queue to complete.

The two problems are related because the one type of URB that isn't
likely to be complete when hcd_endpoint_disable() returns is a root-hub
URB.  Right now usb_rh_urb_dequeue() waits for them to complete, and it
assumes interrupts are enabled so it can wait.  But
hcd_endpoint_disable() calls it with interrupts disabled.

Now, it should be legal to unlink root-hub URBs with interrupts
disabled.  The solution is to move the waiting into
hcd_endpoint_disable(), where it belongs.  This patch (as754) does that.

It turns out to be completely safe to replace the del_timer_sync() with
a simple del_timer().  It doesn't matter if the timer routine is
running; hcd_root_hub_lock will synchronize the two threads and the
status URB will complete with an unlink error, as it should.

USB: Properly unregister reboot notifier in case of failure in ehci hcd

notifier, which in turn leads to crash on reboot/poweroff.

anymore, but instead making ehci/ohci driver get its own shutdown method.  For
PCI, it is done through pci glue, for everything else through platform driver
glue.

One downside: sa1111 does not use platform driver stuff, and does not have its

usbfs: private mutex for open, release, and remove

The usbfs code doesn't provide sufficient mutual exclusion among open,
release, and remove.  Release vs. remove is okay because they both
acquire the device lock, but open is not exclusive with either one.  All
three routines modify the udev->filelist linked list, so they must not
run concurrently.

Apparently someone gave this a minimum amount of thought in the past by
explicitly acquiring the BKL at the start of the usbdev_open routine.
Oddly enough, there's a comment pointing out that locking is unnecessary
because chrdev_open already has acquired the BKL.

But this ignores the point that the files in /proc/bus/usb/* are not
char device files; they are regular files and so they don't get any
special locking.  Furthermore it's necessary to acquire the same lock in
the release and remove routines, which the code does not do.

Yet another problem arises because the same file_operations structure is
accessible through both the /proc/bus/usb/* and /dev/usb/usbdev* file
nodes.  Even when one of them has been removed, it's still possible for
userspace to open the other.  So simple locking around the individual
remove routines is insufficient; we need to lock the entire
usb_notify_remove_device notifier chain.

Rather than rely on the BKL, this patch (as723) introduces a new private
mutex for the purpose.  Holding the BKL while invoking a notifier chain
doesn't seem like a good idea.

Add modalias attribute support for the almost forgotten now EISA bus and

The modalias entry looks like (for an 3c509 NIC):

 eisa:sTCM5093

and the in-module alias like:

 eisa:sTCM5093*

The patch moves struct eisa_device_id declaration from include/linux/eisa.h
to include/linux/mod_devicetable.h (so that the former now #includes the
latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all
drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE
declared), and adds recognision of __mod_eisa_device_table to
scripts/mod/file2alias.c so that proper modules.alias will be generated.

There's no support for /lib/modules/$kver/modules.eisamap, as it's not used
by any existing tools, and because with in-kernel modalias mechanism those
maps are obsolete anyway.

The rationale for this patch is:

 a) to make EISA bus to act as other busses with modalias
    support, to unify driver loading

 b) to foget about EISA finally - with this patch, kernel
    (who still supports EISA) will be the only one who knows
    how to choose the necessary drivers for this bus ;)

[PATCH] x86 microcode: don't check the size

IA32 manual says if micorcode update's size is 0, then the size is
default size (2048 bytes). But this doesn't suggest all microcode
update's size should be above 2048 bytes to me. We actually had a
microcode update whose size is 1024 bytes. The patch just removed the
check.

[PATCH] x86 microcode: add sysfs and hotplug support

Add sysfs support.  Currently each CPU has three microcode related
attributes.  One is 'version' which shows current ucode version of CPU.
Tools can use the attribute do validation or show CPU ucode status.  one is
'reload' which allows manually reloading ucode.  Another is
'processor_flags', which exports processor flags, so we can write tools to
check if CPU has latest ucode.  Also add suspend/resume and CPU hotplug
support.

18 years ago[PATCH] x86 microcode: using request_firmware to pull microcode
Shaohua Li [Wed, 27 Sep 2006 08:50:52 +0000 (01:50 -0700)] 
[PATCH] x86 microcode: using request_firmware to pull microcode

Using request_firmware to pull ucode from userspace, so we don't need the
application 'microcode_ctl' to assist.  We name each ucode file according
to CPU's info as intel-ucode/family-model-stepping.  In this way we could
split ucode file as small one.  This has a lot of advantages such as
selectively update and validate microcode for specific models, better
manage microcode file, easily write tools for administerators and so on.
with the changes, we should put all intel-ucode/xx-xx-xx microcode files
into the firmware dir (I had a tool to split previous big data file into
small one and later we will release new style data file).  The init script
should be changed to just loading the driver without unloading
