* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Having manually bisected kernel versions, I've narrowed it down to some change between 2.6.30 and 2.6.31. There's not much which has changed between the two kernels, but one change stands out like a sore thumb: +static int pdc202xx_test_irq(ide_hwif_t *hwif) +{ + struct pci_dev *dev = to_pci_dev(hwif->dev); + unsigned long high_16 = pci_resource_start(dev, 4); + u8 sc1d = inb(high_16 + 0x1d); + + if (hwif->channel) { + /* + * bit 7: error, bit 6: interrupting, + * bit 5: FIFO full, bit 4: FIFO empty + */ + return ((sc1d & 0x50) == 0x40) ? 1 : 0; + } else { + /* + * bit 3: error, bit 2: interrupting, + * bit 1: FIFO full, bit 0: FIFO empty + */ + return ((sc1d & 0x05) == 0x04) ? 1 : 0; + } +} Reading the (documented as a 32-bit) system control register when the interface is idle gives: 0x01da110c So, the byte at 0x1d is 0x11, which is documented as meaning that the primary and secondary FIFOs are empty. The code above, which is trying to see whether an IRQ is pending, checks for the IRQ bit to be one, and the FIFO bit to be zero - or in English, to be non-empty. Since during a BM-DMA read, the FIFOs will naturally be drained to the PCI bus, the chance of us getting to the interface before this happens are extremely small - and if we don't, it means we decide not to service the interrupt. Hence, the screaming interrupt problem with drivers/ide. Fix this by only indicating an interrupt is ready if both the interrupt and FIFO empty bits are at '1'. This bug only affects PDC20246/PDC20247 (Promise Ultra33) based cards, and has been tested on 2.6.31 and 2.6.33-rc2.

| * | cy82c693: fix PIO timings calculationsBartlomiej Zolnierkiewicz2010-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just use the standard ide_timing_compute() helper to calculate PIO timings. This fixes many issues with the open-coded version like using 16-bit timings when 8-bit ones should be used or not accounting for the enhanced cycle time specified by the device. Based on libata pata_cypress host driver. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
