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:

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.

This patch only deals with the serial port definitions as there is no support for any other xilinx IP cores in the kernel tree at the moment. Board specific configuration moved out of virtex.[ch] and into the xparameters.h wrapper. This also prepares for the transition to the flattened device tree model. When the bootloader provides a device tree generated from an xparameters.h files, the kernel will no longer need xparameters/*. The platform bus will get populated with data from the device tree, and the device drivers will be automatically connected to the devices. Only the bootloader (or ppcboot) will need xparameters directly. Signed-off-by:

The PPC405 hard core is used in both the Virtex-II Pro and Virtex 4 FX FPGAs. This patch cleans up the Virtex naming convention to reflect more than just the Virtex-II Pro. Rename files virtex-ii_pro.[ch] to virtex.[ch] Rename config value VIRTEX_II_PRO to XILINX_VIRTEX Signed-off-by:

xparameters should not be needed by anything but virtex platform code. Move it from include/asm-ppc/ to platforms/4xx/xparameters/ This is preparing for work to remove xparameters from the dependancy tree for most c files. xparam changes should not cause a recompile of the world. Instead, drivers should get device info from the platform bus (populated by the boot code) Signed-off-by:

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.

This addresses two items, which are unlikely to be hit if we trust drivers. The first is moving a memory barrier below where the vmerged SG count is passed back, but before the list is set to end. If those instructions were reordered, there could be an issue in iommu_unmap_sg(). The second is making sure we terminate the list on the failure case of iommu_map_sg(). If a driver does not look at the failure return code, it could pass a ill-formed SG list to iommu_unmap_sg(). Signed-off-by:

You can't boot a kdump kernel via OF, not reliably anyway, the kernel being at 32 MB conflicts with the zImage wrapper etc. and it blows up. It's trivial to check in prom_init though, and this is early enough that we can actually drop back to OF where a reset-all will get you going again, which is kinda nice. I think this should go in for 2.6.16. Signed-off-by:

To prevent problems later in boot, make sure we don't create zero-size lmb regions. I've checked all the callers, and at the moment no one should ever hit this. All callers use a constant size, or they check the computed size before they call us. Signed-off-by:

In prom.c we run finish_node() on allnodes twice. The first time we just calculate how much memory we'll need, the second time we do the actual work. If the calculation stage determines that we need 0 bytes, then we should skip the lmb allocation. Although an alloc of zero will work, it has been seen to lead to a BUG_ON() in reserve_bootmem() on at least one machine. Signed-off-by:
