      [SCSI] qla4xxx: bug fixes · 477ffb9d
      David C Somayajulu authored
      The included patch fixes the following issues:
      
      1. qla3xxx/qla4xxx co-existence issue which can result in a lockup
      when qla3xxx driver is unloaded, or when ifdown; ifup is performed on
      one of the interfaces correponding to qla3xxx. This is because qla4xxx
      HBA supports one ethernet and iscsi interfaces per port. Both iscsi
      and ethernet interfaces share the same state machine. The problem has
      to do with synchronizing access to the state machine in the event of a
      reset
      
      2. mutex_lock() is sometimes not followed by mutex_unlock() prior to
      invoking a msleep() in qla4xxx_mailbox_command()

      [PATCH] fix qla{2,4} build error · d7a297ba
      Frederik Deweerdt authored
      commit 0181944f adds a
      'extended_error_logging' global variable to qla2xxx which is defined by
      qla4xxx too.
      
      Trying to build both drivers results in the following error:
      
        LD      drivers/scsi/built-in.o
        drivers/scsi/qla4xxx/built-in.o: In function `qla4xxx_slave_configure':
        drivers/scsi/qla4xxx/ql4_os.c:1433: multiple definition of `extended_error_logging'
        drivers/scsi/qla2xxx/built-in.o:drivers/scsi/qla2xxx/qla_os.c:2166:
        first defined here
        make[2]: *** [drivers/scsi/built-in.o] Error 1
        make[1]: *** [drivers/scsi] Error 2
        make: *** [drivers] Error 2
      
      The following patch simply adds a qla2_ (qla4_ respectively) prefix to
      the variable name.

      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.
