 +What: __do_IRQ all in one fits nothing interrupt handler
 +When: 2.6.32
 +Why:  __do_IRQ was kept for easy migration to the type flow handlers.
 +      More than two years of migration time is enough.

 +
 +-----------------------------
 +
 +What: obsolete generic irq defines and typedefs
 +When: 2.6.30
 +Why:  The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t)
 +      have been kept around for migration reasons. After more than two years
 +      it's time to remove them finally

++
+ ---------------------------
+ 
+ What: fakephp and associated sysfs files in /sys/bus/pci/slots/
+ When: 2011
+ Why:  In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to
+       represent a machine's physical PCI slots. The change in semantics
+       had userspace implications, as the hotplug core no longer allowed
+       drivers to create multiple sysfs files per physical slot (required
+       for multi-function devices, e.g.). fakephp was seen as a developer's
+       tool only, and its interface changed. Too late, we learned that
+       there were some users of the fakephp interface.
+ 
+       In 2.6.30, the original fakephp interface was restored. At the same
+       time, the PCI core gained the ability that fakephp provided, namely
+       function-level hot-remove and hot-add.
+ 
+       Since the PCI core now provides the same functionality, exposed in:
+ 
+               /sys/bus/pci/rescan
+               /sys/bus/pci/devices/.../remove
+               /sys/bus/pci/devices/.../rescan
+ 
+       there is no functional reason to maintain fakephp as well.
+ 
+       We will keep the existing module so that 'modprobe fakephp' will
+       present the old /sys/bus/pci/slots/... interface for compatibility,
+       but users are urged to migrate their applications to the API above.
+ 
+       After a reasonable transition period, we will remove the legacy
+       fakephp interface.
+ Who:  Alex Chiang <achiang@hp.com>
