2006-02-07[MIPS] TX49x7: Fix reporting of the CPU name and PCI clockSergei Shtylylov
I've noticed that PCI clock was incorrectly reported as 66 MHz while being mere 33 MHz on RBTX4937 board -- this was due to the different encoding of the PCI divisor field in CCFG register between TX4927 and TX4937 chips... Also, RBTX49x7 was printed out as a CPU name (e.g., "CPU is RBTX4937"); and some debug printk() were duplicating each other...

2006-02-07[MIPS] Fix linker script to work for non-4K page size.Ralf Baechle
Very much to my surprise Fuxin Zhang reports this is all it takes to get the kernel to work for page sizes larger than 4kB. This also paves the way for support for the R6000 and R8000 which don't support 4kB page size. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-02-07[MIPS] Support /proc/kcore for MIPSDaniel Jacobowitz
I'm pretty sure that the CKSEG0 bits are wrong, but I did need to cover that region - because the SB-1 kernel links at 0xffffffff80100000 or so, disassembly and printing static variables don't work unless the debugger can read that region.

2006-02-07[MIPS] IP22: Fix serial console detectionRalf Baechle
From: Kaj-Michael Lang <milang@tal.org> In ip22-setup.c the checks for serial/graphics console logic does not check if ARCS console=g but the machine is using serial console, as it does if no keyboard is attached. This patch adds a check if ConsoleOut is serial. There might also be support for other graphics than Newport soon... Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-02-07[MIPS] ieee754[sd]p_neg workaroundAtsushi Nemoto
It looks glibc's pow() assumes an unary '-' operation for any number (including NaNs) always inverts its sign bit (though IEEE754 does not specify the sign bit for NaNs).

2006-02-07[MIPS] Au1xx0: really set KSEG0 to uncached on rebootSergei Shtylylov
Fix a really old buglet in AMD Au1xx0 restart code: instead of modifying the whole CP0 Config.K0 field to 010b (meaning KSEG0 uncached) before flushing the caches and resetting a board, it only sets bit 1 of that reg. which is effectively a NOP since Config.K0 == 011b as the kernel sets it up (which is also its default value for Au1xx0).

2006-01-10[PATCH] sanitize building of fs/compat_ioctl.cChristoph Hellwig
Now that all these entries in the arch ioctl32.c files are gone [1], we can build fs/compat_ioctl.c as a normal object and kill tons of cruft. We need a special do_ioctl32_pointer handler for s390 so the compat_ptr call is done. This is not needed but harmless on all other architectures. Also remove some superflous includes in fs/compat_ioctl.c Tested on ppc64. [1] parisc still had it's PPP handler left, which is not fully correct for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd kick in for all netdevice users. We can introduce a proper handler in one of the next patch series by adding a compat_ioctl method to struct net_device but for now let's just kill it - parisc doesn't compile in mainline anyway and I don't want this to block this patchset.
