linux/blktap2: reduce TLB flush scope

c/s 885 added very coarse TLB flushing. Since these flushes always
follow single page updates, single page flushes (when available) are
sufficient.

1 Module options
2 --------------
4 The mwave module takes the following options. Note that these options
5 are not saved by the BIOS and so do not persist after unload and reload.
7 mwave_debug=value, where value is bitwise OR of trace flags:
8 0x0001 mwavedd api tracing
9 0x0002 smapi api tracing
10 0x0004 3780i tracing
11 0x0008 tp3780i tracing
13 Tracing only occurs if the driver has been compiled with the
14 MW_TRACE macro #defined (i.e. let EXTRA_CFLAGS += -DMW_TRACE
15 in the Makefile).
17 mwave_3780i_irq=5/7/10/11/15
18 If the dsp irq has not been setup and stored in bios by the
19 thinkpad configuration utility then this parameter allows the
20 irq used by the dsp to be configured.
22 mwave_3780i_io=0x130/0x350/0x0070/0xDB0
23 If the dsp io range has not been setup and stored in bios by the
24 thinkpad configuration utility then this parameter allows the
25 io range used by the dsp to be configured.
27 mwave_uart_irq=3/4
28 If the mwave's uart irq has not been setup and stored in bios by the
29 thinkpad configuration utility then this parameter allows the
30 irq used by the mwave uart to be configured.
32 mwave_uart_io=0x3f8/0x2f8/0x3E8/0x2E8
33 If the uart io range has not been setup and stored in bios by the
34 thinkpad configuration utility then this parameter allows the
35 io range used by the mwave uart to be configured.
37 Example to enable the 3780i DSP using ttyS1 resources:
39 insmod mwave mwave_3780i_irq=10 mwave_3780i_io=0x0130 mwave_uart_irq=3 mwave_uart_io=0x2f8
41 Accessing the driver
42 --------------------
44 You must also create a node for the driver. Without devfs:
45 mkdir -p /dev/modems
46 mknod --mode=660 /dev/modems/mwave c 10 219
47 With devfs:
48 mkdir -p /dev/modems
49 ln -s ../misc/mwave /dev/modems/mwave
