(SAL_CALL_REENTRANT): Disable preemption around the SAL call to make sure we don't get rescheduled on a different CPU.

This forces the granule size to 16MB for HP zx1 and generic kernels. HP sx1000 machines require this.

(alloc_resources): Use insert_resource(), not request_resource(), to allocate PCI root bridge windows. This fixes the problem where root bridge window allocation fails because an early driver (like VGA) has already allocated things.

This small fix is needed for machines with more than 128 nodes.

The code in acpi_numa_memory_affinity_init that sorts the node_memblk can overrun the array & clobber the memory that follows the end of the array. The error will be seen only on systems that fill the node_memblk array and only if SAL doesnt sort the entries in the SRAT.

This fixes a bug in the qla1280 driver where it would leave a pointer to an on the stack completion event in a command structure if qla1280_mailbox_command fails. The result is that the interrupt handler later tries to complete() garbage on the stack. The mailbox command can fail if a device on the bus decides to lock up etc.

I just found Yet Another Bug in scsi_ioctl - CDROM_SEND_PACKET puts a kernel pointer in hdr->cmdp, where sg_io() expects to find user address. This worked up until recently because of the memcpy bug, but now it doesn't because we do the proper copy_from_user(). This fix undoes the user copy code from sg_io, and instead makes the SG_IO ioctl copy it locally. This makes SG_IO and CDROM_SEND_PACKET agree on the calling convention, and everybody is happy. I've tested that both cdrecord -dev=/dev/hdc -inq and cdrecord -dev=ATAPI:/dev/hdc -inq works now. The former will use SG_IO, the latter CDROM_SEND_PACKET (and incidentally would work in both 2.4 and 2.6, if it wasn't for CDROM_SEND_PACKET sucking badly in 2.4).

this change: Jim Wilson says that gcc v3.3 also supports marking ar.pfs as clobbered, so use ia64_spinlock_contention() for any GCC with v3.3 or newer.

From Jon Burgess: There is a problems with blank DVD media using the ide-cd driver. When we attempt to read the blank disk, the drive responds to the read request by returning a "blank media" error. The kernel doesn't have any special case handling for this sense value and retries the request a couple of times, then gives up and does a bus reset and disables DMA to the device. Which obviously doesn't help the situation. The sense key value of 8 isn't listed in ide-cd.h, but it is listed in scsi.h as a "BLANK_CHECK" error. This trivial patch treats this error condition as a reason to abort the request. This behaviour is the same as what we do with a blank CD-R. It looks like the same fix might be desired for 2.4 as well, although is perhaps not so important since scsi-ide is normally used instead.

1/ make sure raid5 doesn't try to handle multiple overlaping requests at the same time as this would confuse things badly. Currently it justs BUGs if this is attempted. 2/ Fix a possible data-loss-on-write problem. If two or more bio's that write to the same page are processed at the same time, only the first was actually commited to storage. 3/ Fix a use-after-free bug. raid5 keeps the bio's it is given in linked lists when more than one bio touch a single page. In some cases the tail of this list can be freed, and the current test for 'are we at the end' isn't reliable. This patch strengths the test to make it reliable.

Petr Vandrovec noticed a problem where the thread group leader would not be properly reaped if the parent of the thread group was ignoring SIGCHLD, and the thread group leader had exited before the last sub-thread. Fixed by Ingo Molnar.

This time we have a SMP memory ordering issue in prepare_to_wait(), where we really need to make sure that subsequent tests for the event we are waiting for can not migrate up to before the wait queue has been set up.

In 2.5.x, the BKL was pushed from vfs_readdir() into the filesystem specific functions. But only the unlock_kernel() made it into the HPFS code, lock_kernel() got lost on the way. This rendered the filesystem unusable. This adds the missing lock_kernel(). It's been tested by Timo Maier who also reported the problem earlier today.

The previous scsi_ioctl.c patch didn't cleanup the buffer/bio in the error case. Fix it by copying the command data earlier.

put_user() arguments with function-calls would cause the macro to return unexpected values. Fixed by avoiding macro argument evaluation while r8/r9 are in use for exception-handling purposes. Also, consolidated access-macros so that GCC and Intel compiler use 90% the same code.

corruption on SMP because of another CPU still accessing a waitqueue even after it was de-allocated. Use a careful version of the list emptiness check to make sure we don't de-allocate the stack frame before the waitqueue is all done.

visor.c defines one empty slot in USB ids table that can be filled in at runtime using module parameters. file2alias generates catch-all alias for it: alias usb:v*p*dl*dh*dc*dsc*dp*ic*isc*ip* visor patch adds the same sanity check as in depmod to scripts/file2alias.

This patch was integrated by you in 2.4 six months ago. Unfortunately it never got into 2.5. Without it you can end up with crashes such as http://bugs.debian.org/218670

apart from locking bugs, there are other races. This fixes one with signal delivery. The signal should be delivered _before_ the reciever is woken.

After a bit of mucking around (and possibly finding a bug with debian's libusb/xsane/hotplug interaction, nothing seems to run /etc/hotplug/usb/libusbscanner and thus only root can scan, anyone whose got this working please let me know), the problem does not exist if I only use libusb xsane. How about the following:

James reported a bug in scsi_ioctl.c where it mem copies a user pointer instead of using copy_from_user(). I inadvertently introduced this one when getting rid of CDROM_SEND_PACKET. Here's a trivial patch to fix it.
