2008-08-29pcmcia: cleanup device driver header fileDominik Brodowski3-164/+202
The header file primarily used for (in-kernel) PCMCIA device drivers also deserved a major cleanup. This header file also serves as the dumping ground for all typedefs and definitions only used by the deprecated PCMCIA ioctl and the deprecated PCMCIA userspace tools using this ioctl. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-26pcmcia: cleanup socket services header fileDominik Brodowski2-107/+118
The header file for use by (in-kernel) PCMCIA sockets deserved a major cleanup. Some stuff only used by the pcmcia core modules was moved to cs_internal.h Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-25pcmcia: merge ds_internal.h into cs_internal.hDominik Brodowski5-32/+40
Merge ds_internal.c into cs_internal.h. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-25pcmcia: cleanup cs_internal.hDominik Brodowski1-64/+90
Small cleanup to cs_internal.h. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-25pcmcia: cs_internal.h is internalDominik Brodowski5-5/+0
cs_internal.h is meant for definitions internal to the PCMCIA core modules. It must not be included by PCMCIA socket drivers or by PCMCIA device drivers. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: use dev_printk for cs_error()Dominik Brodowski2-33/+30
Use dev_printk() in cs_error()-based error reporting. While this function-turned-macro will hopefully go away soon, using dev_printk simplifies the code much. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: remove CS_ error codes alltogetherDominik Brodowski2-33/+3
Remoe the CS_ error codes. Drivers are expected to use default error definitions (errno.h etc.). Only one CS_ error code -- CS_IN_USE -- is used internally by the (deprecated) pcmcia-cs userspace package. Therefore, keep this one around so that it still compiles. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_BAD_TUPLEDominik Brodowski5-56/+99
CS_BAD_TUPLE was used to denote a bad tuple being passed to the parse function. Therefore, replace it with -EINVAL and a verbose message. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_BAD_ARGSDominik Brodowski4-11/+12
CS_BAD_ARGS mean a badly written driver or invalid userspace ioctl access, so translate that to -EINVAL. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_BAD_BASE, CS_BAD_IRQ, CS_BAD_OFFSET and CS_BAD_SIZEDominik Brodowski4-19/+22
These four error values mostly mean a badly written driver, so ds_dbg() output and -EINVAL seems to be enough. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_BAD_ATTRIBUTE, CS_BAD_TYPE and CS_BAD_PAGEDominik Brodowski5-30/+37
CS_BAD_TYPE was only used in cs.c and already properly annotated by error messages. CS_BAD_ATTRIBUTE and CS_BAD_PAGE mean a badly written driver, so ds_dbg() output and -EINVAL seems to be enough. (includes bugfix from and Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> ) Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_NO_MORE_ITEMSDominik Brodowski7-11/+11
CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if the end of a tuple chain is reached. As at least one PCMCIA driver relies on matching this return value, replace it with -ENOSPC which is now uniquely used for this purpose within the in-kernel pcmcia subsystem.

2008-08-23pcmcia: deprecate CS_IN_USEDominik Brodowski3-18/+33
If a resource is already in use, mark it with -EBUSY. Same for cards already asleep. (includes a fix for a bug found by Larry Finger -- thanks!) Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_CONFIGURATION_LOCKEDDominik Brodowski3-8/+8
This error code meant that trying to change the configuration after the initialization phase is forbidden. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_BAD_HANDLEDominik Brodowski4-12/+11
CS_BAD_HANDLE means that something went badly wrong: no parameter was passed, or the paramater passed wasn't the correct one. Therefore, replace it with -EINVAL. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_GENERAL_FAILUREDominik Brodowski3-4/+3
It's only used by pcmcia_core when socket-related queries time out. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_NO_CARDDominik Brodowski6-21/+21
It means that no card can be detected in the socket, so return -ENODEV Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_BAD_VCC and CS_BAD_VPPDominik Brodowski3-13/+23
They were either used to report that changing voltage is not allowed, or that changing voltage failed. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_UNSUPPORTED_*Dominik Brodowski6-13/+14
CS_UNSUPPORTED_MODE and CS_UNSUPPORTED_FUNCTION were mostly used to denote trying to use PCMCIA functions on CardBus cards. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_OUT_OF_RESOURCEDominik Brodowski5-33/+50
CS_OUT_OF_RESOURCE was almost only used to note -ENOMEM situations. Therefore, use -ENOMEM explicitely, and also print out warnings. CC: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate unused CS_ error codesDominik Brodowski2-20/+10
Deprecate unused CS_ error codes by replacing their definitions with generic error messages, and removing them from the error_t lookup table. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: deprecate CS_SUCCESSDominik Brodowski35-212/+233
Instead of using own error or success codes, the PCMCIA code should rely on the generic return values. Therefore, replace all occurrences of CS_SUCCESS with 0. CC: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: move config_info_t definition to ioctl-related parts in header filesDominik Brodowski2-21/+21

2008-08-23pcmcia: move pccard_get_configuration_info to ioctlDominik Brodowski4-81/+72
With the PCMCIA ioctl being the only remaining user of _get_configuration_info, move the function to pcmcia_ioctl.c Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: remove remaining in-kernel pcmcia_get_configuration_info() usersDominik Brodowski3-30/+10
Remove the three remaining pcmcia_get_configuration_info() users: - pcmciamtd is marked broken anyway. - serial_cs.c can access the relevant structs directly - ipwireless didn't use the output CC: linux-serial@vger.kernel.org CC: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: David Sterba <dsterba@suse.cz> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: don't add extra DEBUG cflagDominik Brodowski13-19/+15
Use CONFIG_PCMCIA_DEBUG instead of DEBUG so that dev_dbg() and other tricks work properly. (includes bugfixes from and Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> ) Signed-off-by: Dominik Broodwski <linux@dominikbrodowski.net>

2008-08-23pcmcia: pcmcia_config_loop() improvement by passing vccDominik Brodowski32-142/+93
By passing the current Vcc setting to the pcmcia_config_loop callback function, we can remove pcmcia_get_configuration_info() calls from many drivers. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: pcmcia_config_loop() default CIS entry handlingDominik Brodowski32-165/+158
Many drivers use the default CIS entry within their pcmcia_config_loop() callback function. Therefore, factor the default CIS entry handling out. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: pcmcia_config_loop() ConfigIndex unificationDominik Brodowski29-46/+6
Almost all drivers set p_dev->conf.ConfigIndex to cfg->index in the pcmcia_config_loop() callback function. Therefore, factor it out. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2008-08-23pcmcia: add pcmcia_loop_config() helperDominik Brodowski3-0/+74
By calling pcmcia_loop_config(), a pcmcia driver can iterate over all available configuration options. During a driver's probe() phase, one doesn't need to use pcmcia_get_{first,next}_tuple, pcmcia_get_tuple_data and pcmcia_parse_tuple directly in most if not all cases.

2008-07-28Fix 'get_user_pages_fast()' with non-page-aligned start addressLinus Torvalds1-3/+6
Alexey Dobriyan reported trouble with LTP with the new fast-gup code, and Johannes Weiner debugged it to non-page-aligned addresses, where the new get_user_pages_fast() code would do all the wrong things, including just traversing past the end of the requested area due to 'addr' never matching 'end' exactly. This is not a pretty fix, and we may actually want to move the alignment into generic code, leaving just the core code per-arch, but Alexey verified that the vmsplice01 LTP test doesn't crash with this.

2008-07-29lguest: turn Waker into a thread, not a processRusty Russell1-63/+57
lguest uses a Waker process to break it out of the kernel (ie. actually running the guest) when file descriptor needs attention. Changing this from a process to a thread somewhat simplifies things: it can directly access the fd_set of things to watch. More importantly, it means that the Waker can see Guest memory correctly, so /dev/vring file descriptors will work as anticipated (the alternative is to actually mmap MAP_SHARED, but you can't do that with /dev/zero).

2008-07-29lguest: Adaptive timeoutRusty Russell1-1/+11
Since the correct timeout value varies, use a heuristic which adjusts the timeout depending on how many packets we've seen.
