set_cp0_* and change_cp0_* which makes the kernel code somewhat more
readable. Going through the kernel code I notices some stupid abuse of
the old function like set_cp0_status(ST0_BEV, 1) - this clear ST0_BEV
but actually looks like attempting to set it and other abuses, so will
people please look over their code again.

of rejects to fixup while integrating Linus patches. I also found
that this kernel will only boot SMP on Origin; the UP kernel freeze
soon after bootup with SCSI timeout messages. I commit this anyway
since I found that the last CVS versions had the same problem.

o only code for the configured CPU is compiled
and linked (saves ~100k for R3000 kernels!)
o removed a lot of indirect function calls
o removed Ralf's "cowboy patch"
o added sanity check for DECstations (print warning
if the kernel is configured for the wrong CPU)

o New G364 console code.

user would expect it to work, like under IRIX with the exception
that the machine doesn't freeze solid as long as the button is
pressed.
o Realtime clock driver (CONFIG_SGI_DS1286) for the Indy. Includes
/proc/rtc interface which tells you everything about your RTC which
you never wanted to know. You have to configure this driver into
your kernel or you won't be able to set your RTC.
o Some cleanup of the RTC interfaces in Linux, RTC does no longer mean
PC-style RTC. The userland interface definitions are now in
<linux/rtc.h>. We still need some more cleanup until we can enable
several RTC drivers.
o Virtual aliasing fixes for ptrace(2).
o Add ptrace(2) interface definitions needed to build GDB to
<asm/ptrace.h>.
o Revert to some older routines, the newer optimized ones are buggy.
o On panic the Indy LED will be blinking fast crying to the admin
passing by [music from Rocky Horror show] ``fix me, fix me, fix
me''.
o On panic the power button will only reboot the machine, not power it
down. That's probably more what people want it to do.
o Remove some old files.
o Did I tell you that CVS is buggy?

o First round of bugfixes for the SC/MC CPUs.
o FPU context switch fixes.
o Lazy context switches.
o Faster syscalls.
o Removed dead code.
o Shitloads of other things I forgot ...

Pentium :-)
o Little bit smarter handling of unimplemented exceptions.
o Fix FPU context switches.
o Fix reboot / halt. Powerdown in software still doesn't work.
o Fix the fix for handling of return values of interrupted syscalls.
o Handling of the Indy second level cache now works as spec'ed. Purely
cosmentic, this was not causing any problems.

o Just count missed heartbeats on Indys but don't print a messages. This
was a bug by itself.
o Fix a crash in exit_mmap().
o Fix scanmem().
o Fix clear_active_bh(), a ~ was missing causing weak performance.
o Remove experimental cache instructions from stackframe.h. It wasn't
improving performance as I was hoping.
o Shrink the size of the exception handler routines in uaccess.h.
o Cleanup, remove dead code in various files.
|

o New faster syscalls for 2.1.x, too
o Upgrade to 2.1.89.
Don't try to run this. It's flaky as hell. But feel free to debug ...

On some MIPS boxes the firmware doesn't do that for us.
- We still had two unprotected loads in the sys_sigrestore(2). Use
__get_user().
- Handle QED-style L1 caches != 16kb per cache correctly.
- Protect the cacheflush instructions for the signal trampoline
just like the loads in __get_user(). Otherwise the following
code will result in a nice "Can not handle kernel paging request"
message:
#include <signal.h>
static void hurz(void)
{
}
main()
{
signal(SIGSEGV, hurz);
/* Chainsaw the stack pointer ... */
asm("move $29,%0" : :"r"(0x70000000));
*(int *) 8 = 0;
}
With the fix applied I still get the error message. The cause of
this problem is that gas produces an __ex_table section with wrong
contents. Oh well, how good that I have a nice working post 2.8.1
binutils version at home in good ol' Germany ...

IMPORTANT NOTE: I could not figure out what information is the
one that should be used for the following files (ie, those
that were in our tree, or those that came from Linus' patch),
please, check these:
include/asm-mips/jazz.h
include/asm-mips/jazzdma.h
include/asm-mips/ioctls.h

Add missing return that was causing all processes receiving a
signal to be terminated with a SIGSEGV.
