The msi-laptop driver uses input_*() and sparse_keymap_*() interfaces. It should depend on the INPUT subsystem being present and select INPUT_SPARSEKMAP so that those interfaces are present.

According to Thomas, the former is the correct direct conversion, but it does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c seems to initialize both to the same thing), and the chip data in some ways is the more logical. Somebody should really decide on one of the other. This merge picks irq_desc_get_handler_data() as the straightforward pure conversion to new names, as per Thomas.

It initializes mapping->a_ops with a NULL pointer for some pages in nilfs (e.g. btree node pages), but mm code doesn't NULL pointer checks against mapping->a_ops. (the check is done for each callback function) This corrects the aops initialization and fixes the oops. Signed-off-by:

From the result of a function test of mmap, mmap write to shared pages turned out to be broken for hole blocks. It doesn't write out filled blocks and the data will be lost after umount. This is due to a bug that the target file is not queued for log writer when filling hole blocks. Also, nilfs_page_mkwrite function exits normal code path even after successfully filled hole blocks due to a change of block_page_mkwrite function; just after nilfs was merged into the mainline, block_page_mkwrite() started to return VM_FAULT_LOCKED instead of zero by the patch "mm: close page_mkwrite races" (commit: b827e496 ). The current nilfs_page_mkwrite() is not handling this value properly. This corrects nilfs_page_mkwrite() and will resolve the data loss problem in mmap write. [This should be applied to every kernel since 2.6.30 but a fix is needed for 2.6.37 and prior kernels] Signed-off-by:

commit cf9efce0 (powerpc: Account time using timebase rather than PURR) used in_irq() to detect if the time was spent in interrupt processing. This only catches hardirq context so if we are in softirq context and in the idle loop we end up accounting it as idle time. If we instead use in_interrupt() we catch both softirq and hardirq time. The issue was found when running a network intensive workload. top showed the following: 0.0%us, 1.1%sy, 0.0%ni, 85.7%id, 0.0%wa, 9.9%hi, 3.3%si, 0.0%st 85.7% idle. But this was wildly different to the perf events data. To confirm the suspicion I ran something to keep the core busy: # yes > /dev/null & 8.2%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 10.3%hi, 81.4%si, 0.0%st We only got 8.2% of the CPU for the userspace task and softirq has shot up to 81.4%. With the patch below top shows the correct stats: 0.0%us, 0.0%sy, 0.0%ni, 5.3%id, 0.0%wa, 13.3%hi, 81.3%si, 0.0%st Signed-off-by:

Milton Miller authored
commit 79f26c26 (powerpc: platforms/pseries irq_data conversion) pushed irq_desc down into many functions, dererencing the descriptor irq field as late as possible. But it incorrectly passed a linix virtural irq number to RTAS, resulting in the interrupt not being disabled and possibly other bad things, such as another interrupt being disabled and/or a checkstop. In addition this missed the point of xics_mask_unknown_vec and the seperation of xics_mask_real_irq from xics_mask_irq. When xics_mask_unknown_vec is called it's because the hardware delivered an irq source for which we have no linux irq allocated, and thefore we can not have an irq_desc allocated. Revert xics_mask_real_irq to its prior version, naming the argument hwirq to highlight the difference. Signed-off-by:

Uwe Kleine-König reported: while working on an defconfig (arm/mx27) I noticed that just updating it[1] results in removing CONFIG_EEPROM_AT24=y. The reason is that since commit v2.6.36-5965-g5f2365d8 (misc devices: do not enable by default) MISC_DEVICES isn't enabled anymore by default. So all defconfigs that have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same problem. This restores those misc devices to the powerpc defconfigs. Signed-off-by:
