making a powerpc target with PCI support, shows the following warning: MODPOST vmlinux.o WARNING: vmlinux.o(.text+0x10430): Section mismatch in reference from the function pcibios_allocate_bus_resources() to the function .init.text:reparent_resources() The function pcibios_allocate_bus_resources() references the function __init reparent_resources(). This is often because pcibios_allocate_bus_resources lacks a __init annotation or the annotation of reparent_resources is wrong. This patch fix this warning by removing the __init annotation before reparent_resources. Signed-off-by: NHeiko Schocher <hs@denx.de> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

We need to align before the output section. Having the align inside the output section causes the linker to put some filler in there, which makes it a non-empty section, but this section isn't assigned to a segment so you get a warning from the linker.

Profiling of a page fault scalability microbenchmark shows flush_hash_range is not calling the batch hpte invalidate hcall (H_BULK_REMOVE). It turns out we have a duplicate firmware feature for hcall-bulk and the current setup code stops after finding the first match. This meant we never batch and always do individual invalidates. The patch below removes the duplicate and shifts FW_FEATURE_CMO to close the gap. With the patch applied the single threaded page fault rate improves from 217169 to 238755 per second on a POWER5 test box, a 10% improvement.

On pSeries, we always force the IO space to be mapped using 4K pages even with a 64K base page size to cope with some limitations in the HV interface to some devices. However, the SLB miss handler code to discriminate between vmalloc and ioremap space uses a CPU feature section such that the code is nop'ed out when the processor support large pages non-cachable mappings. Thus, we end up always using the ioremap page size for vmalloc segments on such processors, causing a discrepency between the segment and the hash table, and thus a hang continously hashing the page. It works for the first segment of the vmalloc space since that segment is "bolted" in by C code correctly, and thankfully we almost never use the vmalloc space beyond the first segment, but the new percpu code made the bug happen. This fixes it by removing the feature section from the assembly, we now always do the comparison between vmalloc and ioremap.

Since the change of how interrupts are disabled during suspend, certain PowerBook models started exhibiting various issues during suspend or resume from sleep. I finally tracked it down to the code that runs various "platform" functions (kind of little scripts extracted from the device-tree), which uses our i2c and PMU drivers expecting interrutps to work, and at a time where with the new scheme, they have been disabled. This causes timeouts internally which for some reason results in the PMU being unable to see the trackpad, among other issues, really it depends on the machine. Most of the time, we fail to properly adjust some clocks for suspend/resume so the results are not always predictable. This patch fixes it by using IRQF_TIMER for both the PMU and the I2C interrupts. I prefer doing it this way than moving the call sites since I really want those platform functions to still be called after all drivers (and before sysdevs). We also do a slight cleanup to via-pmu.c driver to make sure the ADB autopoll mask is handled correctly when doing bus resets Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

The mod_return_to_handler needs to switch to the kernel TOC before jumping to a the kernel code. It currently does this by looking at the kernel function data and retrieves the TOC that way. Not only is this inefficient, it also breaks with a relocatable kernel. The PACA contains the kernel TOC and we can easily retrieve it that way.

When the function graph tracer is enabled, it replaces the return address with a hook back to the tracer. This makes back traces see the hook instead of the actual return address. The current code also shows the real address by checking if the return address jumps to the return_to_handler. If it is, is also prints out the saved real return address. On powerpc64, some modules may return to mod_return_to_handler, which is not checked. This patch will also show the real address if a return is to mod_return_to_handler as well.

After a reboot on an ARM1176 which amounts to a softreset, it has been noted that the ALSA driver does not get registered and the probe fails with the error "aaci-pl041 fpga:04: ac97 read back fail". In the process of reading from a register the SL1TxBusy bit is set indicating that the transceiver is busy and remains so until the default timeout occurs. Set the Power down register 0x26 to an arbitrary value as specified in the PL041 manual (page: 3-18) so that AACISL1TX/AACISL2TX registers take their default state.

On FSC laptops, the sound gets muted gradually when the volume is chnaged. This is due to the wrong volume-knob widget setup. The delta bit (bit 7) shouldn't be set for these devices.

On ARM, update_mmu_cache() does dcache flush for a page only if it has a kernel mapping (page_mapping(page) != NULL). The correct behavior would be to force the flush based on dcache_dirty bit only. One of the cases where present logic would be a problem is when a RAM based block device[1] is used as a swap disk. In this case, we would have in-memory data corruption as shown in steps below: do_swap_page() { - Allocate a new page (if not already in swap cache) - Issue read from swap disk - Block driver issues flush_dcache_page() - flush_dcache_page() simply sets PG_dcache_dirty bit and does not actually issue a flush since this page has no user space mapping yet. - Now, if swap disk is almost full, this newly read page is removed from swap cache and corrsponding swap slot is freed. - Map this page anonymously in user space. - update_mmu_cache() - Since this page does not have kernel mapping (its not in page/swap cache and is mapped anonymously), it does not issue dcache flush even if dcache_dirty bit is set by flush_dcache_page() above. <user now gets stale data since dcache was never flushed> } Same problem exists on mips too. [1] example: - brd (RAM based block device) - ramzswap (RAM based compressed swap device) Signed-off-by: NNitin Gupta <ngupta@vflare.org> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Having this as a device_initcall() means that some real device drivers can actually initialise _before_ the quirks are run, which is wrong. We want it to run _before_ device_initcall(), but _after_ fs_initcall(), since some arch-specific PCI initialisation like pcibios_assign_resources() is done at fs_initcall(). We could use rootfs_initcall() but I actually want to use that for the IOMMU initialisation, which has to come after the quirks, but still before the real devices. So use fs_initcall_sync() instead -- since this is entirely synchronous, it doesn't hurt that it'll escape the synchronisation. Signed-off-by: NDavid Woodhouse <David.Woodhouse@intel.com>
