* [IA64] prevent sn2 specific code to be run in generic kernelsJes Sorensen2006-02-082-3/+7
| | | | | | | | Prevent SN2 specific code to be executed on non SN2 platforms when running a generic kernel. Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] Fix CONFIG_PRINTK_TIMETony Luck2006-02-074-13/+59
| | | | | | | | | | | | | | There were two problems with enabling the PRINTK_TIME config option: 1) The first calls to printk() occur before per-cpu data virtual address is pinned into the TLB, so sched_clock() can fault. 2) sched_clock() is based on ar.itc, which may not be synchronized across cpus. Ken Chen started this patch, Tony Luck tinkered with it, and Jes Sorensen perfected it. Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] Fix wrong use of memparse in efi.cZou Nan hai2006-02-071-11/+3
| | | | | | | | | | | The check of (end != cp) after memparse in efi.c looks wrong to me. The result is that we can't use mem= and max_addr= kernel parameter at the same time. The following patch removed the check just like other arches do. Signed-off-by: Zou Nan hai <nanhai.zou@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * [MIPS] Clear ST0_RE on bootup.Ralf Baechle2006-02-071-1/+1
| | | | | | | | | | | | | | The reset state is undefined and some firmware doesn't clear this bit possibly resulting in crashes on entry into userland. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
| * [MIPS] TX49x7: Fix reporting of the CPU name and PCI clockSergei Shtylylov2006-02-073-49/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | 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...

| * [MIPS] TX49 MFC0 bug workaroundAtsushi Nemoto2006-02-071-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If mfc0 $12 follows store and the mfc0 is last instruction of a page and fetching the next instruction causes TLB miss, the result of the mfc0 might wrongly contain EXL bit. ERT-TX49H2-027, ERT-TX49H3-012, ERT-TX49HL3-006, ERT-TX49H4-008 Workaround: mask EXL bit of the result or place a nop before mfc0. It doesn't harm to always clear those bits, so we change the code to do so. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
| * [MIPS] Fix linker script to work for non-4K page size.Ralf Baechle2006-02-071-5/+6
| | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | 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).
