      pcmcia: Fix up legacy driver IRQs · 47cbb110
      Alan Cox 提交于
      The PCMCIA layer obsoleted asking for per device private IRQS some years
      ago and all the drivers by inspection correctly use dev_id and handle
      shared interrupts [they get em anyway in most PCI bridged PCMCIA/Cardbus]
      so can be adjusted.
      
      This gets rid of the various bugs reported where there is spewage about
      conflicting irq types and sometimes the driver won't load.
      
      (Note I don't have all of these devices to test each one beyond by inspection)

      [netdrvr] Drivers should not set IFF_* flag themselves · c16d1185
      Wang Chen 提交于
      Some hardware set promisc when they are requested to set IFF_ALLMULTI flag.
      It's ok, but if drivers set IFF_PROMISC flag when they set promisc,
      it will broken upper layer handle for promisc and allmulti.
      In addition, drivers can use their own hardware programming to make it.
      So do not allow drivers to set IFF_* flags.
      
      This is a general driver fix, so I didn't split it to pieces and send
      to specific driver maintainers.

      wavelan_cs: stop inlining largish static functions · 2aee82de
      Denys Vlasenko 提交于
      Hi John,
      
      Can you please take a look at this patch?
      
      drivers/net/wireless/wavelan_cs.c has unusually large number
      of static inline functions - 27.
      
      I looked through them and 20 of them do not seem to warrant inlining.
      Some are really big; others call mdelay(1) or busy-wait for a bit
      to be set in a hardware register - it's pointless
      to optimize such functions for speed.
      
      This patch removes "inline" from these static function
      (regardless of number of callsites - gcc nowadays auto-inlines
      statics with one callsite).
      
      Size difference for 32bit x86:

      [PATCH] getting rid of all casts of k[cmz]alloc() calls · 5cbded58
      Robert P. J. Day 提交于
      Run this:
      
      	#!/bin/sh
      	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
      	  echo "De-casting $f..."
      	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
      	done
      
      And then go through and reinstate those cases where code is casting pointers
      to non-pointers.
      
      And then drop a few hunks which conflicted with outstanding work.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells 提交于
      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.

      [NET]: Avoid allocating skb in skb_pad · 5b057c6b
      Herbert Xu 提交于
      First of all it is unnecessary to allocate a new skb in skb_pad since
      the existing one is not shared.  More importantly, our hard_start_xmit
      interface does not allow a new skb to be allocated since that breaks
      requeueing.
      
      This patch uses pskb_expand_head to expand the existing skb and linearize
      it if needed.  Actually, someone should sift through every instance of
      skb_pad on a non-linear skb as they do not fit the reasons why this was
      originally created.
      
      Incidentally, this fixes a minor bug when the skb is cloned (tcpdump,
      TCP, etc.).  As it is skb_pad will simply write over a cloned skb.  Because
      of the position of the write it is unlikely to cause problems but still
      it's best if we don't do it.

      [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback · f8cfa618
      Dominik Brodowski 提交于
      Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
      probe() callback. As all in-kernel drivers are changed to this new
      callback, there will be no temporary backwards-compatibility. Inside a
      probe() function, each driver _must_ set struct pcmcia_device
      *p_dev->instance and instance->handle correctly.
      
      With these patches, the basic driver interface for 16-bit PCMCIA drivers
      now has the classic four callbacks known also from other buses:
      
              int (*probe)            (struct pcmcia_device *dev);
              void (*remove)          (struct pcmcia_device *dev);
      
              int (*suspend)          (struct pcmcia_device *dev);
              int (*resume)           (struct pcmcia_device *dev);
