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.

12 If you say Y here, your kernel will be able to manage low cost mass
13 storage units such as ATA/(E)IDE and ATAPI units. The most common
14 cases are IDE hard drives and ATAPI CD-ROM drives.
16 If your system is pure SCSI and doesn't use these interfaces, you
17 can say N here.
19 Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
20 for mass storage units such as hard disks. It was designed by
21 Western Digital and Compaq Computer in 1984. It was then named
22 ST506. Quite a number of disks use the IDE interface.
24 AT Attachment (ATA) is the superset of the IDE specifications.
25 ST506 was also called ATA-1.
27 Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
28 ATA-3. It provides support for larger disks (up to 8.4GB by means of
29 the LBA standard), more disks (4 instead of 2) and for other mass
30 storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
31 ATA-4 and provides faster (and more CPU friendly) transfer modes
32 than previous PIO (Programmed processor Input/Output) from previous
33 ATA/IDE standards by means of fast DMA controllers.
35 ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
36 CD-ROM drives, similar in many respects to the SCSI protocol.
38 SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
39 designed in order to prevent data corruption and disk crash by
40 detecting pre hardware failure conditions (heat, access time, and
41 the like...). Disks built since June 1995 may follow this standard.
42 The kernel itself doesn't manage this; however there are quite a
43 number of user programs such as smart that can query the status of
44 SMART parameters from disk drives.
46 To compile this driver as a module, choose M here: the
47 module will be called ide.
49 For further information, please read <file:Documentation/ide.txt>.

67 If you say Y here, you will use the full-featured IDE driver to
68 control up to ten ATA/IDE interfaces, each being able to serve a
69 "master" and a "slave" device, for a total of up to twenty ATA/IDE
70 disk/cdrom/tape/floppy drives.
72 Useful information about large (>540 MB) IDE disks, multiple
73 interfaces, what to do if ATA/IDE devices are not automatically
74 detected, sound card ATA/IDE ports, module support, and other
75 topics, is contained in <file:Documentation/ide.txt>. For detailed
76 information about hard drives, consult the Disk-HOWTO and the
77 Multi-Disk-HOWTO, available from
78 <http://www.tldp.org/docs.html#howto>.
80 To fine-tune ATA/IDE drive/interface parameters for improved
81 performance, look for the hdparm package at
82 <ftp://ibiblio.org/pub/Linux/system/hardware/>.
84 To compile this driver as a module, choose M here and read
85 <file:Documentation/ide.txt>. The module will be called ide-mod.
86 Do not compile this driver as a module if your root file system (the
87 one containing the directory /) is located on an IDE device.
89 If you have one or more IDE drives, say Y or M here. If your system
90 has no IDE drives, or if memory requirements are really tight, you
91 could say N here, and select the "Old hard disk driver" below
92 instead to save about 13 KB of memory in the kernel.

101 ---help---
102 There are two drivers for Serial ATA controllers.
104 The main driver, "libata", exists inside the SCSI subsystem
105 and supports most modern SATA controllers.
107 The IDE driver (which you are currently configuring) supports
108 a few first-generation SATA controllers.
110 In order to eliminate conflicts between the two subsystems,
111 this config option enables the IDE driver's SATA support.
112 Normally this is disabled, as it is preferred that libata
113 supports SATA controllers, and this (IDE) driver supports
114 PATA controllers.

122 There are two drivers for MFM/RLL/IDE disks. Most people use just
123 the new enhanced driver by itself. This option however installs the
124 old hard disk driver to control the primary IDE/disk interface in
125 the system, leaving the new enhanced IDE driver to take care of only
126 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from
127 having an IDE/ATAPI CD-ROM or tape drive connected to the primary
128 IDE interface. Choosing this option may be useful for older systems
129 which have MFM/RLL/ESDI controller+drives at the primary port
130 address (0x1f0), along with IDE drives at the secondary/3rd/4th port
131 addresses.
133 Normally, just say N here; you will then use the new driver for all
134 4 interfaces.

171 If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
172 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
173 SCSI protocol. Most new CD-ROM drives use ATAPI, including the
174 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
175 double(2X) or better speed drives.
177 If you say Y here, the CD-ROM drive will be identified at boot time
178 along with other IDE devices, as "hdb" or "hdc", or something
179 similar (check the boot messages with dmesg). If this is your only
180 CD-ROM drive, you can say N to all other CD-ROM options, but be sure
181 to say Y or M to "ISO 9660 CD-ROM file system support".
183 Note that older versions of LILO (LInux LOader) cannot properly deal
184 with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from

195 ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
196 similar to the SCSI protocol. If you have an SCSI tape drive
197 however, you can say N here.
199 You should also say Y if you have an OnStream DI-30 tape drive; this
200 will not work with the SCSI protocol, until there is support for the
201 SC-30 and SC-50 versions.
203 If you say Y here, the tape drive will be identified at boot time
204 along with other IDE devices, as "hdb" or "hdc", or something
205 similar, and will be mapped to a character device such as "ht0"
206 (check the boot messages with dmesg). Be sure to consult the
207 <file:drivers/ide/ide-tape.c> and <file:Documentation/ide.txt> files

218 drives, similar to the SCSI protocol.

221 this driver. For information about jumper settings and the question
222 of when a ZIP drive uses a partition table, see
223 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>.

239 WARNING: ide-scsi is no longer needed for cd writing applications!
240 The 2.6 kernel supports direct writing to ide-cd, which eliminates
241 the need for ide-scsi + the entire scsi stack just for writing a
242 cd. The new method is more efficient in every way.
244 This will provide SCSI host adapter emulation for IDE ATAPI devices,
245 and will allow you to use a SCSI device driver instead of a native
246 ATAPI driver.
248 This is useful if you have an ATAPI device for which no native
249 driver has been written (for example, an ATAPI PD-CD drive);
250 you can then use this emulation together with an appropriate SCSI
251 device driver. In order to do this, say Y here and to "SCSI support"
252 and "SCSI generic support", below. You must then provide the kernel
253 command line "hdx=ide-scsi" (try "man bootparam" or see the
254 documentation of your boot loader (lilo or loadlin) about how to
255 pass options to the kernel at boot time) for devices if you want the
256 native EIDE sub-drivers to skip over the native support, so that
257 this SCSI emulation can be used instead.
259 Note that this option does NOT allow you to attach SCSI devices to a
260 box that doesn't have a SCSI host adapter installed.
262 If both this SCSI emulation and native ATAPI support are compiled
263 into the kernel, the native support will be used.

289 "SiS" chipset. Unfortunately, it has a number of rather nasty
290 design flaws that can cause severe data corruption under many common

292 detect and correct the problems under Linux. This option also
293 enables access to the secondary IDE ports in some CMD640 based
294 systems.
296 This driver will work automatically in PCI based systems (most new
297 systems have PCI slots). But if your system uses VESA local bus
298 (VLB) instead of PCI, you must also supply a kernel boot parameter

1064 There are two drivers for MFM/RLL/IDE hard disks. Most people use

1066 reasons. Some older systems have strange timing problems and seem to
1067 work only with the old driver (which itself does not work with some
1068 newer systems). The other reason is that the old driver is smaller,
1069 since it lacks the enhanced functionality of the new one. This makes
1070 it a good choice for systems with very tight memory restrictions, or
1071 for systems with only older MFM/RLL/ESDI drives. Choosing the old
