Drivers, drivers, drivers. IrDA and ISDN. PPC.
The most interesting part is probably the exclusive wait-queue patch. David Miller noticed that exclusivity doesn't nest correctly the way we used to do it: being on multiple wait-queues would potentially cause lost wake-up events if a non-exclusive waiter got mistaken for an exclusive one because the exclusive bit was a per-process thing.
Moving the exclusivity bit from the process into the wait-queue cleaned up the interfaces and also made it nest properly.
No known uses were actually buggy, but at least one case was apparently ok only by pure luck.

----- - pre3: - James Simmons: vgacon "printk()" deadlock with global irq lock. - don't poke blanked console on console output - Ching-Ling: get channels right on ALI audio driver - Dag Brattli and Jean Tourrilhes: big IrDA update - Paul Mackerras: PPC updates - Randy Dunlap: USB ID table support, LEDs with usbkbd, belkin serial converter. - Jeff Garzik: pcnet32 and lance net driver fix/cleanup - Mikael Pettersson: clean up x86 ELF_PLATFORM - Bartlomiej Zolnierkiewicz: sound and drm driver init fixes and cleanups - Al Viro: Jeff missed some kmap()'s. sysctl cleanup - Kai Germaschewski: ISDN updates - Alan Cox: SCSI driver NULL ptr checks - David Miller: networking updates, exclusive waitqueues nest properly, SMP i_shared_lock/page_table_lock lock order fix.
- pre2: - Stephen Rothwell: directory notify could return with the lock held - Richard Henderson: CLOCKS_PER_SEC on alpha. - Jeff Garzik: ramfs and highmem: kmap() the page to clear it - Asit Mallick: enable the APIC in the official order - Neil Brown: avoid rd deadlock on io_request_lock by using a private rd-request function. This also avoids unnecessary request merging at this level. - Ben LaHaise: vmalloc threadign and overflow fix - Randy Dunlap: USB updates (plusb driver). PCI cacheline size. - Neil Brown: fix a raid1 on top of lvm bug that crept in in pre1 - Alan Cox: various (Athlon mmx copy, NULL ptr checks for scsi_register etc). - Al Viro: fix /proc permission check security hole. - Can-Ru Yeou: SiS301 fbcon driver - Andrew Morton: NMI oopser and kernel page fault punch through both console_lock and timerlist_lock to make sure it prints out.. - Jeff Garzik: clean up "kmap()" return type (it returns a kernel virtual address, ie a "void *"). - Jeff Garzik: network driver docs, various one-liners. - David Miller: add generic "special" flag to page flags, to be used by architectures as they see fit. Like keeping track of cache coherency issues. - David Miller: sparc64 updates, make sparc32 boot again - Davdi Millner: spel "synchronous" correctly - David Miller: networking - fix some bridge issues, and correct IPv6 sysctl entries. - Dan Aloni: make fork.c use proper macro rather than doing get_exec_domain() by hand.
- pre1: - me: make PCMCIA work even in the absense of PCI irq's - me: add irq mapping capabilities for Cyrix southbridges - me: make IBMMCA compile right as a module - me: uhhuh. Major atomic-PTE SMP race boo-boo. Fixed. - Andrea Arkangeli: don't allow people to set security-conscious bits in mxcsr through ptrace SETFPXREGS. - Jürgen Fischer: aha152x update - Andrew Morton, Trond Myklebust: file locking fixes - me: TLB invalidate race with highmem - Paul Fulghum: synclink/n_hdlc driver updates - David Miller: export sysctl_jiffies, and have the proper no-sysctl version handy - Neil Brown: RAID driver deadlock and nsfd read access to execute-only files fix - Keith Owens: clean up module information passing, remove "get_module_symbol()". - Jeff Garzik: network (and other) driver fixes and cleanups - Andrea Arkangeli: scheduler cleanup. - Ching-Ling Li: fix ALi sound driver memory leak - Anton Altaparmakov: upcase fix for NTFS - Thomas Woller: CS4281 audio update
