Tejun's recent eighty_ninty_three() fix has inspired me to do more thorough review of the cable detection code... * print user-friendly warning about limiting the maximum transfer speed to UDMA33 (and the reason behind it) when 80-wire cable is not detected, also while at it cleanup eighty_ninty_three() a bit * use eighty_ninty_three() in ide_ata66_check(), this actually fixes 3 bugs: - bit 14 (word 93 validity check) == 1 && bit 13 (80-wire cable test) == 1 were used as 80-wire cable present test for CONFIG_IDEDMA_IVB=n case (please see FIXME comment in eighty_ninty_three() for more details) - CONFIG_IDEDMA_IVB=y/n cases were interchanged - check for SATA devices was missing * remove private cable warnings from pdc_202xx{old,new} drivers now that core code provides this functionality (plus, in pdc202xx_new case the test could give false warnings for ATAPI devices because pdc202xx_new driver doesn't even support ATAPI DMA) Cc: Tejun Heo <htejun@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* do write permission and min/max checks in ide_procset_t functions * ide-disk.c: drive->id is always available so cleanup "multcount" setting accordingly * ide-disk.c: "address" setting was incorrectly defined as type TYPE_INTA, fix it by using type TYPE_BYTE and updating ide_drive_t->adressing field, the bug didn't trigger because this IDE setting uses custom ->set function * ide.c: add set_ksettings() for handling HDIO_SET_KEEPSETTINGS ioctl * ide.c: add set_unmaskirq() for handling HDIO_SET_UNMASKINTR ioctl * handle ioctls directly in generic_ide_ioclt() and idedisk_ioctl() instead of using IDE settings to deal with them * remove no longer needed ide_find_setting_by_ioctl() and {read,write}_ioctl fields from ide_settings_t, also remove now unused TYPE_INTA handling v2: * add missing EXPORT_SYMBOL_GPL(ide_setting_sem) needed now for ide-disk Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

All important information/features should be already available through sysfs and ioctl interfaces. Add CONFIG_IDE_PROC_FS (CONFIG_SCSI_PROC_FS rip-off) config option, disabling it makes IDE driver ~5 kB smaller (on x86-32). While at it add CONFIG_PROC_FS=n versions of proc_ide_{create,destroy}() and remove no longer needed #ifdefs. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Depends on the "ide: fix UDMA/MWDMA/SWDMA masks" patch. * add ide_hwif_t.udma_filter hook for filtering UDMA mask (use it in alim15x3, hpt366, siimage and serverworks drivers) * add ide_max_dma_mode() for finding best DMA mode for the device (loosely based on some older libata-core.c code) * convert ide_dma_speed() users to use ide_max_dma_mode() * make ide_rate_filter() take "ide_drive_t *drive" as an argument instead of "u8 mode" and teach it to how to use UDMA mask to do filtering * use ide_rate_filter() in hpt366 driver * remove no longer needed ide_dma_speed() and *_ratemask() * unexport eighty_ninty_three() v2: * rename ->filter_udma_mask to ->udma_filter [ Suggested by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ] v3: * updated for scc_pata driver (fixes XFER_UDMA_6 filtering for user-space originated transfer mode change requests when 100MHz clock is used) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

H. Peter Anvin authored
In the process of rewriting the x86 setup code, I found a number of inaccuracies and outdated recommendations in the boot protocol documentation. Revamp to make it more up to date. In particular, the common use of the heap actually requires (slightly) more than 4K of heap plus stack, which is the recommended amount in the document; currently the code compensates by being smaller than specified, but we can't assume that will be true forever. Thus, recommend that if we have a modern bzImage kernel, that the bootloader maximizes the available space. Signed-off-by: H.

Miscellaneous fixes to bring FRV up to date: (1) Copy the new syscall numbers from i386 to asm-frv/unistd.h and fill out the syscall table in entry.S too. (2) Mark __frv_uart0 and __frv_uart1 __pminitdata rather than __initdata so that determine_clocks() can access them when CONFIG_PM=y. (3) Make arch/frv/mm/elf-fdpic.c include asm/mman.h so that MAP_FIXED is available (fixes commit 2fd3beba).

This reverts commit 464bdd33. Peter Anvin correctly points out that VESA modes have nothing to do with frame buffers per se - they are often just regular extended text modes.

The idea is to move more and more things into the pbm, with the eventual goal of eliminating the pci_controller_info entirely as there really isn't any need for it. This stage of the transformations requires some reworking of the PCI error interrupt handling. It might be tricky to get rid of the pci_controller_info parenting for a few reasons: 1) When we get an uncorrectable or correctable error we want to interrogate the IOMMU and streaming cache of both PBMs for error status. These errors come from the UPA front-end which is shared between the two PBM PCI bus segments. Historically speaking this is why I choose the datastructure hierarchy of pci_controller_info-->pci_pbm_info 2) The probing does a portid/devhandle match to look for the 'other' pbm, but this is entirely an artifact and can be eliminated trivially. What we could do to solve #1 is to have a "buddy" pointer from one pbm to another. Signed-off-by: David S. Miller <davem@davemloft.net>
