      USB: convert drivers/usb/* to use module_usb_driver() · 65db4305
      Greg Kroah-Hartman authored
      This converts the drivers in drivers/usb/* to use the
      module_usb_driver() macro which makes the code smaller and a bit
      simpler.
      
      Added bonus is that it removes some unneeded kernel log messages about
      drivers loading and/or unloading.

      USB: use usb_endpoint_maxp() instead of le16_to_cpu() · 29cc8897
      Kuninori Morimoto authored
      Now ${LINUX}/drivers/usb/* can use usb_endpoint_maxp(desc) to get maximum packet size
      instead of le16_to_cpu(desc->wMaxPacketSize).

      USB: prevent char device open/deregister race · d4ead16f
      Alan Stern authored
      This patch (as908) adds central protection in usbcore for the
      prototypical race between opening and unregistering a char device.
      The spinlock used to protect the minor-numbers array is replaced with
      an rwsem, which can remain locked across a call to a driver's open()
      method.  This guarantees that open() and deregister() will be mutually
      exclusive.
      
      The private locks currently used in several individual drivers for
      this purpose are no longer necessary, and the patch removes them.  The
      following USB drivers are affected: usblcd, idmouse, auerswald,
      legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and
      usb-skeleton.
      
      As a side effect of this change, usb_deregister_dev() must not be
      called while holding a lock that is acquired by open().  Unfortunately
      a number of drivers do this, but luckily the solution is simple: call
      usb_deregister_dev() before acquiring the lock.
      
      In addition to these changes (and their consequent code
      simplifications), the patch fixes a use-after-free bug in adutux and a
      race between open() and release() in iowarrior.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells authored
      Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
      of passing regs around manually through all ~1800 interrupt handlers in the
      Linux kernel.
      
      The regs pointer is used in few places, but it potentially costs both stack
      space and code to pass it around.  On the FRV arch, removing the regs parameter
      from all the genirq function results in a 20% speed up of the IRQ exit path
      (ie: from leaving timer_interrupt() to leaving do_IRQ()).
      
      Where appropriate, an arch may override the generic storage facility and do
      something different with the variable.  On FRV, for instance, the address is
      maintained in GR28 at all times inside the kernel as part of general exception
      handling.
      
      Having looked over the code, it appears that the parameter may be handed down
      through up to twenty or so layers of functions.  Consider a USB character
      device attached to a USB hub, attached to a USB controller that posts its
      interrupts through a cascaded auxiliary interrupt controller.  A character
      device driver may want to pass regs to the sysrq handler through the input
      layer which adds another few layers of parameter passing.
      
      I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
      main part of the code on FRV and i386, though I can't test most of the drivers.
      I've also done partial conversion for powerpc and MIPS - these at least compile
      with minimal configurations.
      
      This will affect all archs.  Mostly the changes should be relatively easy.
      Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
      
      	struct pt_regs *old_regs = set_irq_regs(regs);
      
      And put the old one back at the end:
      
      	set_irq_regs(old_regs);
      
      Don't pass regs through to generic_handle_irq() or __do_IRQ().
      
      In timer_interrupt(), this sort of change will be necessary:
      
      	-	update_process_times(user_mode(regs));
      	-	profile_tick(CPU_PROFILING, regs);
      	+	update_process_times(user_mode(get_irq_regs()));
      	+	profile_tick(CPU_PROFILING);
      
      I'd like to move update_process_times()'s use of get_irq_regs() into itself,
      except that i386, alone of the archs, uses something other than user_mode().
      
      Some notes on the interrupt handling in the drivers:
      
       (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
           the input_dev struct.
      
       (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
           something different depending on whether it's been supplied with a regs
           pointer or not.
      
       (*) Various IRQ handler function pointers have been moved to type
           irq_handler_t.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
