2007-07-06[MIPS] AP/SP: Avoid triggering the 34K E125 performance issueRalf Baechle1-4/+0
C0_status doesn't need to be initialized at this point anyway; the register will be initialized later. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-06-26[MIPS] EMMA2RH: Disable GEN_RTC, it can't possibly work.Ralf Baechle1-2/+1
Neither rtc_mips_get_time nor rtc_mips_set_time are being initialized by the EMMA2RH setup code, so genrtc at best was a RTC dummy avoiding a few error messages but not providing actual functionality. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-06-26[MIPS] 20K: Handle WAIT related bugs according to errata informationRalf Baechle1-1/+11
We used to avoid the WAIT entirely on the 20K but really only need to do this on early revs of the 20K. Without this a 20K was a bit of a power hog. Well, in the lower power power hog category ;-) Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-06-11[MIPS] SMTC: Don't set and restore irqregs ptr from self_ipi.Ralf Baechle1-3/+0
This did corrupt register s0 which the caller of self_ipi expects to be unchanged. This is a kernel bug which will only be triggered with the compilers which compile __smtc_ipi_replay to use s0 across the invocation of self_ipi. Gcc 4.1.2 does this, for example.

2007-05-24meth driver renovationRalf Baechle2-1/+21
The meth ethernet driver for the SGI IP32 aka O2 is so far still an old style driver which does not use the device driver model. This is now causing issues with some udev based gadgetry in debian-stable. Fixed by converting the meth driver to a platform device.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan2-2/+2
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%).
