15 years agox86: clean up the APIC_DEST_LOGICAL logic

x86: clean up the APIC_DEST_LOGICAL logic

Impact: cleanup

The bigsmp and es7000 subarchitectures un-defined APIC_DEST_LOGICAL in
a rather nasty way by re-defining it to zero. That is infinitely
fragile and makes it very hard to see what to code really does in
a given context. The very same constant has different meanings and
values - depending on which subarch is enabled.

Untangle this mess by never undefining the constant, but instead
propagating the right values into the genapic driver templates.

Most subarchitectures want to disable the APIC ESR (Error Status Register),
because they generally have hardware hacks that wrap standard CPUs into
a bigger system and hence the APIC bus is quite non-standard and weirdnesses

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_ISOC

This patch (as1198) fixes a conceptual bug: Somewhere along the line
we managed to confuse USB class devices with USB char devices.  As a
result, the code to send a disconnect signal to userspace would not be
built if both CONFIG_USB_DEVICE_CLASS and CONFIG_USB_DEVICEFS were
disabled.

The usb_fs_classdev_common_remove() routine has been renamed to
usbdev_remove() and it is now called whenever any USB device is
removed, not just when a class device is unregistered.  The notifier
registration and unregistration calls are no longer conditionally
compiled.  And since the common removal code will always be called as
part of the char device interface, there's no need to call it again as
part of the usbfs interface; thus the invocation of
usb_fs_classdev_common_remove() has been taken out of
usbfs_remove_device().

Commit a0d4922da2e4ccb0973095d8d29f36f6b1b5f703
(USB: fix up suspend and resume for PCI host controllers) attempted
to fix the suspend-resume of PCI USB controllers, but unfortunately
it did that incorrectly and interrupts are left enabled by the USB
controllers' ->suspend_late() callback as a result.  This leads to
serious problems during suspend which are very difficult to debug.

Fix the issue by removing the ->suspend_late() callback of PCI
USB controllers and moving the code from there to the ->suspend()
callback executed with interrupts enabled.  Additionally, make
the ->resume() callback of PCI USB controllers execute
pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the
full power state (PCI_D0).

system, but wakeup is not enabled by default.

It turns out that enabling wakeup for USB host controllers has a lot
of bad consequences.  As the simplest example, if a USB mouse or
keyboard is unplugged immediately after the computer is put to sleep,
the unplug will cause the system to wake back up again!  We are better

USB: fix toggle mismatch in disable_endpoint paths

This patch (as1200) finishes some fixes that were left incomplete by
an earlier patch.

Although nobody has addressed this issue in the past, it turns out
that we need to distinguish between two different modes of disabling
and enabling endpoints.  In one mode only the data structures in
usbcore are affected, and in the other mode the host controller and
device hardware states are affected as well.

The earlier patch added an extra argument to the routines in the
enable_endpoint pathways to reflect this difference.  This patch adds
corresponding arguments to the disable_endpoint pathways.  Without
this change, the endpoint toggle state can get out of sync between
the host and the device.  The exact mechanism depends on the details
of the host controller (whether or not it stores its own copy of the
toggle values).
