* new helper atapi_cdb_len() in linux/ata.h, use it after IDENTIFY PACKET DEVICE command completes * add new taskfile protocol ATA_PROT_ATAPI_NODATA * store scsi cdb in ata_queued_cmd. This removes another dependence on the scsi layer, and enables us to issue an internal REQUEST SENSE. * store cdb len in ata_port * new constant ATAPI_CDB_LEN for max cdb length * move ATA taskfile and SCSI cdb near the top of ata_queued_cmd, for better cacheline friendliness.

The hardware vendor, in their infinite wisdom, make the combined mode configuration register different between ICH5 and ICH6. Take this into account.

Move hand-coded ATA Data register I/O from ata_pio_sector() to its own function ata_data_xfer(), so that it may also be used to send the ATAPI packet to hardware. Use ata_data_xfer() in ATAPI packet send. Separate ATA and ATAPI completion functions.

rather than hand-rolling our own taskfile call (which won't work at all on newer SATA controllers). Individual changes: * use ata_qc_issue to issue identify-device command * implement MMIO path for PIO data xfer * implement PIO error handling path

In the transfer-mode cleanup recently, the code that set flag ATA_DFLAG_PIO disappeared. Resurrect it. Remove ATA_QCFLAG_DMA, it isn't needed. Always set polling in the ->qc_issue function, rather than force the user to do it when setting up an ata_queued_cmd. This gives maximum flexibility to the driver, letting the driver choose whether or not to poll.

As ->vm_private_data is used as a cursor for swapout of VM_NONLINEAR vmas, the check for NULL ->vm_private_data or VM_RESERVED is too strict, and should allow VM_NONLINEAR vmas with non-NULL ->vm_private_data. This fixes an issue on 2.6.7-mm5 where system calls to remap_file_pages() spuriously failed while under memory pressure. Signed-off-by:

For 32-bit, one quickly discovers that swapon() is not given an fd already opened with O_LARGEFILE to act upon and the forcing of O_LARGEFILE for 64-bit is irrelevant, as the system call's argument is a path. So this patch manually forces it for swapon() and swapoff(). Signed-off-by:

With the following changes, I was able to compile the "sparc" (32 bit) arch, using defconfig and crosstool. There were still plenty of warnings, but nothing else relating to bitops or cpumasks that I noticed. This is working with 2.6.7-mm5. I have no way to boot test this, but these changes seem obvious enough that I'd recommend including them. Signed-off-by:

It looks like someone removed UPF_RESOURCES in remove-upf_resources.patch in parallel with someone adding drivers/firmware/pcdp.c that references UPF_RESOURCES. In any event, trying to build a defconfig ia64 2.6.7-mm5 (which includes CONFIG_SERIAL_8250=y in the .config) fails with: drivers/firmware/pcdp.c: In function `setup_serial_console': drivers/firmware/pcdp.c:100: error: `UPF_RESOURCES' undeclared (first use in this function) Signed-off-by:

At the moment, we initialise physnode_map from the various BIOS tables, which can create problems, as holes inside an node return 1 for pfn_valid, and yet pfn_to_nid is not correct for them. I'd hacked around this in my tree by defaulting the mapping to 0, not -1, but that's not the correct fix ... this is. I consolidated all the code back into 1 place, and use node_start_pfn[] and node_end_pfn[] to walk over it instead - that means it matches up perfectly with lmem_map's as we're using the same data. It also cleans up a lot of the code. Tested on both NUMA-Q and x440 ... and it only affects i386 NUMA boxen. Signed-off-by:

From: Linas Vepstas <linas@austin.ibm.com> When an RTAS call returns the "hardware error" code, we need to do another RTAS call to find out what went wrong. Previously we weren't doing that inside the lock that serializes RTAS calls, and thus another cpu could get in and do another RTAS call in the meantime. This patch fixes it. This patch also includes some minor whitespace fixes. Signed-off-by:

From: Linas Vepstas <linas@austin.ibm.com> This patch fixes the usage of the slot-error-detail log buffer for the Power5 architecture. The size of the error buffer is variable, and the correct size to use should have been obtained from firmware. Failure to use the correct buffer sizes will result in hard-to-debug system lockups deep in firmware. This patch is based on an earlier patch from Ben Herrenschmidt, which essentially did the same thing. This patch also tweaks some of the subroutine documentation. Signed-off-by:

From: Linas Vepstas <linas@austin.ibm.com> This patch allows ppc64 to boot on Power5 machines. The new Power5 PCI bridge design requires EEH (enhanced PCI error handling) to be enabled for all PCI devices, not just some PCI devices. In addition, this patch moves the check for PCI to ISA bridges out of perf critical code, and into initialization code. This also avoids race conditions where the device type might not have been set. Also, some whitespace fixes, and some error-message-printing beautification. Signed-off-by:
