pcmcia: remove obsolete host controller drivers

2026-03-30T05:28:13+00:00

PCMCIA is almost completely obsolete (the last computers supporting it natively were from ~2009), and the general consensus [1] seems to be that support for it should be gradually removed from the kernel. In 2023, an initial step of removing all the PCMCIA char drivers was taken in commit 9b12f050c76f ("char: pcmcia: remove all the drivers"), and that has not been reverted, so it seems logical to continue this process by removing more low-hanging fruit. These host controller drivers have had no meaningful changes since their status was discussed in 2022 [2], and are unlikely to have any remaining users. Remove them and a couple references to them in comments. The i82365 and tcic drivers are for ISA-attached host controllers, which are even less likely to be used nowadays than ones on other buses. The i82092 driver has almost certainly not been used in over 20 years. It was broken by a null pointer dereference since the dawn of Git history (2.6.12-rc2 in 2005) until someone fixed it in 2021 in commit e39cdacf2f66 ("pcmcia: i82092: fix a null pointer dereference bug"). From their dmesg log [3], it is clear they were testing in an emulated environment and not on real hardware. i82365.h is used by drivers other than i82365 and is therefore retained.

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

pcmcia: tcic: remove unneeded "&" in call to setup_timer()

The second parameter is the entry address of the function, and therefore does not require an "&". Signed-off-by: lizhe [linux@dominikbrodowski.net: update commit message] Signed-off-by: Dominik Brodowski

drivers/pcmcia: Convert timers to use timer_setup()

2017-11-02T22:50:50+00:00

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

Annotate hardware config module parameters in drivers/pcmcia/

2017-04-20T11:02:32+00:00

When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in drivers/pcmcia/. Suggested-by: Alan Cox Signed-off-by: David Howells cc: linux-pcmcia@lists.infradead.org

pcmcia: drop owner assignment from platform_drivers

pcmcia: convert pcmcia_request_configuration to pcmcia_enable_device

2010-09-29T15:20:23+00:00

pcmcia_enable_device() now replaces pcmcia_request_configuration(). Instead of config_req_t, all necessary flags are either passed as a parameter to pcmcia_enable_device(), or (in rare circumstances) set in struct pcmcia_device -> flags. With the last remaining user of include/pcmcia/cs.h gone, remove all references.

pcmcia: remove cs_types.h

2010-07-30T19:07:39+00:00

Remove cs_types.h which is no longer needed: Most definitions aren't used at all, a few can be made away with, and two remaining definitions (typedefs, unfortunatley) may be moved to more specific places.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32+00:00

percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
