This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed. Signed-off-by:

LMB_ALLOC_ANYWHERE doesn't need to be part of the API, it's only used in lmb.c - so move it out of the header file. Signed-off-by:

Michael Ellerman authored
Currently most callers of lmb_alloc() don't check if it worked or not, if it ever does weird bad things will probably happen. The few callers who do check just panic or BUG_ON. So make lmb_alloc() panic internally, to catch bugs at the source. The few callers who did check the result no longer need to. The only caller that did anything interesting with the return result was careful_allocation(). For it we create __lmb_alloc_base() which _doesn't_ panic automatically, a little messy, but passable.

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. Signed-off-by:

Since 404849bb we've been using LOAD_REG_ADDRBASE, which uses the toc pointer, in decrementer_iSeries_masked. 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. Signed-off-by:

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:

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:

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.
