2006-02-07[IA64] Fix wrong use of memparse in efi.cZou Nan hai
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>

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...

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).

2006-02-07[PATCH] powerpc: avoid timer interrupt replay effect when onlining cpuNathan Lynch
When a cpu is hotplug-onlined, if we don't set per_cpu(last_jiffy) to something sane, timer_interrupt will execute its while loop for every tick missed since the cpu was last online (or since the system was booted, if we're adding a new cpu). This can cause weird hangs, ssh sessions dropping, and we can even go xmon if we take a global IPI at the wrong time.

This can explode if we take the decrementer interrupt while we're in a module, because the toc pointer in r2 will be the module's toc pointer.

2006-02-07[PATCH] powerpc: Cleanup, consolidating icache dirtying logicDavid Gibson
The code to mark a page as icache dirty (so that it will later be icache-dcache flushed when we try to execute from it) is duplicated in three places: flush_dcache_page() does this marking and nothing else, but clear_user_page() and copy_user_page() duplicate it, since those functions make the page icache dirty themselves. This patch makes those other functions call flush_dcache_page() instead, so the logic's all in one place. This will make life less confusing if we ever need to tweak the details of the the lazy icache flush mechanism. arch/powerpc/mm/mem.c | 14 ++------------ 1 file changed, 2 insertions(+), 12 deletions(-) Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-02-07[PATCH] powerpc: Don't overwrite flat device tree with kdump kernelMichael Ellerman
It's possible for prom_init to allocate the flat device tree inside the kdump crash kernel region. If this happens, when we load the kdump kernel we overwrite the flattened device tree, which is bad. We could make prom_init try and avoid allocating inside the crash kernel region, but then we run into issues if the crash kernel region uses all the space inside the RMO. The easiest solution is to move the flat device tree once we're running in the kernel. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-02-07[PATCH] powerpc: remove useless call to touch_softlockup_watchdogDave C Boutcher
It turns out that we can't stop the watchdog from triggering here. If we touch the timer (which just uses the current jiffie value) before we enable interrupts, it does nothing because jiffies are not mass-updated until after we enable interrupts. If we touch the timer after we enable interrupts, its too late because the softlockup watchdog will already have triggered. The touch_softlockup_watchdog call removed below does nothing.
