2008-04-26ide-disk: add proc_idedisk_read_smart() helperBartlomiej Zolnierkiewicz
* Factor out common code from proc_idedisk_read_smart_{thresholds,values}() to proc_idedisk_read_smart() helper. * Rename proc_idedisk_read_smart_thresholds() to proc_idedisk_read_st() and proc_idedisk_read_smart_values() to proc_idedisk_read_sv(). There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-26ide: use ide_find_port() in legacy VLB host drivers (take 2)Bartlomiej Zolnierkiewicz
* Add IDE_HFLAG_QD_2ND_PORT host flag to indicate the need of skipping first ide_hwifs[] slot for the second port of QD65xx controller. * Handle this new host flag in ide_find_port_slot(). * Convert legacy VLB host drivers to use ide_find_port(). While at it: * Fix couple of printk()-s in qd65xx host driver to not use hwif->name. v2: * Fix qd65xx. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: merge ide_match_hwif() and ide_find_port()Bartlomiej Zolnierkiewicz
* Change ide_match_hwif() argument from 'u8 bootable' to 'struct ide_port_info *d'. * Move ide_match_hwif() to ide-probe.c from setup-pci.c and rename it to ide_find_port_slot(). Update some comments while at it. * ide_find_port() can be now just a wrapper for ide_find_port_slot(). There should be no functional changes caused by this patch.

2008-04-26ide: use DIV_ROUND_UPJulia Lawall
The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable.

2008-04-26ide: IDE_HFLAG_BOOTABLE -> IDE_HFLAG_NON_BOOTABLEBartlomiej Zolnierkiewicz
"bootable" should be the default behavior so replace IDE_HFLAG_BOOTABLE host flag with IDE_HFLAG_NON_BOOTABLE. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-26ide: make ide_pci_check_iomem() actually workSergei Shtylyov
This function didn't actually check if a given BAR is in I/O space because of using the bogus PCI_BASE_ADDRESS_IO_MASK (which equals ~3) to test the resource flags instead of IORESOURCE_IO -- fix this, make ide_hwif_configure() check the results failing if necessary, and move the printk() call to the failure path.

This lifts the code diddling the TF and DF bits for signal handler setup out of the several places copying the same code into the one place that calls them all. There is no change in what it does. I also separated the recently-added DF bit clearing from the TF diddling. The compiler turns them back into one instruction anyway. The tossing in of DF to the same line of code with no new comments was a bit more arcane than seems wise. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86: remove NexGen supportDmitri Vorobiev
It is claimed that NexGen CPUs were never shipped: http://lkml.org/lkml/2008/4/20/179 Also, the kernel support for these chips has been broken for a long time, the code intended to support NexGen thereby being essentially dead. As an outcome of the discussion that can be found using the URL above, this patch removes the NexGen support altogether. The changes in this patch survived a defconfig build for i386, a couple of successful randconfig builds, as well as a runtime test, which consisted in booting a 32-bit x86 box up to the shell prompt.

2008-04-26x86-64: extend MCE CPU quirk handlingJan Beulich
At least on my Barcelona, I see MCE log entries after cold boot caused by BIOS not properly clearing the respective registers. Therefore, this patch extends the workaround to families 0x10 and 0x11 (the latter just for completeness, I have nothing to verify this against). At the same time, provide a way to make these entries visible via the 'mce=bootlog' command line option even on these machines.
