| |/ | | | | | | | | | | | | | | | | MTD_XIP depends on having working asm/mtd-xip.h; it's not just per-architecture (arm-only, as current Kconfig would have it), but actually per-subarch as well. Introduced a new symbol (ARCH_MTD_XIP) set by arch Kconfig; MTD_XIP depends on it. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* / [PATCH] alpha: set cpu_possible_map much earlierIvan Kokshaysky2006-02-08
|/ | | | | | | | | | | | | All the percpu data structure walkers want cpu_possible_map to be initialized early, but alpha instead populated "hwrpb_cpu_present_mask" early in setup_smp(), and then initialized cpu_possible_map only much later. Thanks go to Heiko Carstens and Dipankar Sarma for noticing. This fixes it and we can get rid of hwrpb_cpu_present_mask entirely. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * | [PATCH] powerpc: avoid timer interrupt replay effect when onlining cpuNathan Lynch2006-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | [PATCH] powerpc: Cleanup, consolidating icache dirtying logicDavid Gibson2006-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | [PATCH] powerpc: Don't overwrite flat device tree with kdump kernelMichael Ellerman2006-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

| * | [PATCH] powerpc: Refuse to boot a kdump kernel via OFMichael Ellerman2006-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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