The docs still have entries for stdcall, but all recent snapshots choke on __switch_to()...
egcs-2.93.21 -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 -fno-omit-frame-pointer -g1 -pg -pipe -DCPU=586 -mcpu=pentium -march=pentium -c -o process.o process.c process.c:718: conflicting types for `__switch_to' /usr/src/linux/include/asm/system.h:15: previous declaration of `__switch_to' make[1]: *** [process.o] Error 1
from 2.2.8-pre4+ikd/include/asm/system.h... #ifndef CONFIG_KERNEL_DEBUGGING /* Fix the FASTCALL thing -arca */ extern void FASTCALL(__switch_to(struct task_struct *prev, struct task_struct *next)); #else extern void __switch_to(struct task_struct *prev, struct task_struct *next) __attribute__((stdcall)); #endif
and from 2.2.8-pre4+ikd/include/linux/kernel.h #if defined(__i386__) && !defined(CONFIG_KERNEL_DEBUGGING) #define FASTCALL(x) x __attribute__((regparm(3))) #else #define FASTCALL(x) x #endif
egcs-1.1.2, older snapshots and various other gcc versions are ok with the prototype.

[ ] Attribute usage changed? [ ] It has a bug? [ ] It hates me? [*] Nope, no ideas that don't generate instant reboot. :)
