* [ISDN] HiSax hfc_pci: minor cleanupsJeff Garzik2007-07-17
| | | | | | | | | | | * trim trailing whitespace * remove CONFIG_PCI ifdefs, this driver is always PCI (Kconfig enforced) * remove return statements at the tail of a function * remove indentation levels by returning an error code immediately. Makes the code much more readable, and easier to update to PCI hotplug API. Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [ISDN] HiSax bkm_a4t: split setup into two smaller functionsJeff Garzik2007-07-17

* [ISDN] HiSax netjet_s: code movement, prep for hotplugJeff Garzik2007-07-17
| | | | | | | | | | | | | 1) Remove CONFIG_PCI ifdefs. PCI is required in Kconfig. 2) Break up setup_netjet_s() into three separate internal functions. This helps facilitate upcoming use of PCI hotplug API, and in addition makes the code much easier to follow. No code is changed, just moved around. I even kept the out-of-favor "return(0)" style used in the current source code. Signed-off-by: Jeff Garzik <jeff@garzik.org>

* isdn/capi warning fixesAndrew Morton2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | drivers/isdn/capi/capi.c: In function 'handle_minor_send': drivers/isdn/capi/capi.c:552: warning: cast from pointer to integer of different size Of course, the code here might actually be buggy, in which case this patch should not be applied? Answer: No this field is ignored inside linux kernel.Yes this is ugly, but it's the CAPI spec for all OS. CAPI DATA_B3 Request/Indication CAPI Message has a mandatory field which represent the 32 bit buffer address of the payload data. In linux the payload data do not use a sperate buffer, data follows directely after the CAPI Message in the same skb and we use this assumption inside the drivers, so we can ignore this field. Inside the linux CAPI implemetation we never use this field, so it could also have no value, but since random data in a message is bad as well (e.g. displayed in CAPI traces) we set is to the most adequate value. Outside the kernel the capi20 library sets the correct addresses (there is an optional second field for 64 bit adresses for 64 bit systems, we do not use here).

* PCI: Change all drivers to use pci_device->revisionAuke Kok2007-07-11
| | | | | | | | | | | | | | | | | | | | Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

* Detach sched.h from mm.hAlexey Dobriyan2007-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.

Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually.

* [PATCH] Fix buffer overflow and races in capi debug functionsKarsten Keil2007-03-01
| | | | | | | | | | | | | The CAPI trace debug functions were using a fixed size buffer, which can be overflowed if wrong formatted CAPI messages were sent to the kernel capi layer. The code was also not protected against multiple callers. This fix bug 8028. Additionally the patch make the CAPI trace functions optional.
