      [IrDA]: KingSun/DonShine USB IrDA dongle support. · a2af421f
      Alex Villac�s Lasso 提交于
      This dongle does not follow the usb-irda specification, so it needs its
      own special driver. In addition, it uses interrupt endpoints instead of
      bulk ones as the rest of USB IrDA dongles supported by Linux (just to be
      different?) and data reads need to be parsed to extract the valid bytes
      before being unwrapped (details in the comment at the start of the
      source). No speed commands have been discovered for this dongle, and I
      suspect it does not have any at all.
      
      On plugin, this dongle reports vendor and device IDs: 0x07c0:0x4200 .
      
      The Windows driver that is used normally to control this dongle has a
      filename of DSIR620.SYS .

      [ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXX · 7053acbd
      Eric Miao 提交于
      This patch removes the unnecessary bit number from CKENnn_XXXX
      definitions for PXA, so that
      
      	CKEN0_PWM0 --> CKEN_PWM0
      	CKEN1_PWM1 --> CKEN_PWM1
      	...
      	CKEN24_CAMERA --> CKEN_CAMERA
      
      The reasons for the change of these defitions are:
      
      1. they do not scale - they are currently valid for pxa2xx, but
      definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera
      instead of bit 24
      
      2. they are unnecessary - the peripheral name within the definition
      has already announced its usage, we don't need those bit numbers
      to know which peripheral we are going to enable/disable clock for
      
      3. they are inconvenient - think about this: a driver programmer
      for pxa has to remember which bit in the CKEN register to turn
      on/off
      
      Another change in the patch is to make the definitions equal to its
      clock bit index, so that
      
         #define CKEN_CAMERA  (24)
      
      instead of
      
         #define CKEN_CAMERA  (1 << 24)
      
      this change, however, will add a run-time bit shift operation in
      pxa_set_cken(), but the benefit of this change is that it scales
      when bit index exceeds 32, e.g., pxa3xx has two registers CKENA
      and CKENB, totally 64 bit for this, suppose CAMERA clock enabling
      bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10)
      and so that pxa_set_cken() need minimum change to adapt to that.

      [ARM] 4295/2: Fix error-handling in pxaficp_ir.c (version 2) · 9a4d93d4
      Guennadi Liakhovetski 提交于
      This patch addresses the following issues with the pxa2xx FIr driver:
      
      1. increment overrun error counter and not frame error counter on ICSR1_ROR bit set in ICSR1.
      2. drop frames reported with the frame error from the IC.
      3. when resetting the receiver and preparing it for the next DMA in pxa_irda_fir_irq() actually clear the Rx FIFO. See description in Table 11-2 in PXA270 Developer's Manual of the RXE bit.
      
      Correction added in version 2: clearing the IC Rx FIFO also has to be done in pxa_irda_fir_dma_tx_irq()

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau 提交于
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
      recently, it makes sense again to remove other superfluous sched.h includes.
      There are quite a lot of files which include it but don't actually need
      anything defined in there.  Presumably these includes were once needed for
      macros that used to live in sched.h, but moved to other header files in the
      course of cleaning it up.
      
      To ease the pain, this time I did not fiddle with any header files and only
      removed #includes from .c-files, which tend to cause less trouble.
      
      Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
      arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
      allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
      configs in arch/arm/configs on arm.  I also checked that no new warnings were
      introduced by the patch (actually, some warnings are removed that were emitted
      by unnecessarily included header files).

      [PATCH] tty: switch to ktermios · 606d099c
      Alan Cox 提交于
      This is the grungy swap all the occurrences in the right places patch that
      goes with the updates.  At this point we have the same functionality as
      before (except that sgttyb() returns speeds not zero) and are ready to
      begin turning new stuff on providing nobody reports lots of bugs
      
      If you are a tty driver author converting an out of tree driver the only
      impact should be termios->ktermios name changes for the speed/property
      setting functions from your upper layers.
      
      If you are implementing your own TCGETS function before then your driver
      was broken already and its about to get a whole lot more painful for you so
      please fix it 8)
      
      Also fill in c_ispeed/ospeed on init for most devices, although the current
      code will do this for you anyway but I'd like eventually to lose that extra
      paranoia

      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.

      USB: Dealias -110 code (more complete) · 38e2bfc9
      Pete Zaitcev 提交于
      The purpose of this patch is to split off the case when a device does
      not reply on the lower level (which is reported by HC hardware), and
      a case when the device accepted the request, but does not reply at
      upper level. This redefinition allows to diagnose issues easier,
      without asking the user if the -110 happened "immediately".
      
      The usbmon splits such cases already thanks to its timestamp, but
      it's not always available.
      
      I adjusted all drivers which I found affected (by searching for "urb").
      Out of tree drivers may suffer a little bit, but I do not expect much
      breakage. At worst they may print a few messages.

      [PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_private · 8e18e294
      Theodore Ts'o 提交于
      The following patches reduce the size of the VFS inode structure by 28 bytes
      on a UP x86.  (It would be more on an x86_64 system).  This is a 10% reduction
      in the inode size on a UP kernel that is configured in a production mode
      (i.e., with no spinlock or other debugging functions enabled; if you want to
      save memory taken up by in-core inodes, the first thing you should do is
      disable the debugging options; they are responsible for a huge amount of bloat
      in the VFS inode structure).
      
      This patch:
      
      The filesystem or device-specific pointer in the inode is inside a union,
      which is pretty pointless given that all 30+ users of this field have been
      using the void pointer.  Get rid of the union and rename it to i_private, with
      a comment to explain who is allowed to use the void pointer.  This is just a
      cleanup, but it allows us to reuse the union 'u' for something something where
      the union will actually be used.
