2006-01-06[PATCH] x86: Fixed pnp bios limitsZachary Amsden
PnP BIOS data, code, and 32-bit entry segments all have fixed limits as well; set them in the GDT rather than adding more code. It would be nice to add these fixups to the boot GDT rather than setting the GDT for each CPU; perhaps I can wiggle this in later, but getting it in before the subsys init looks tricky. Also, make some progress on deprecating the ugly Q_SET_SEL macros.

2006-01-06[PATCH] x86: Pnp byte granularityZachary Amsden
The one remaining caller of set_limit, the PnP BIOS code, calls into the PnP BIOS, passing kernel parameters in and out. These parameteres may be passed from arbitrary kernel virtual memory, so they deserve strict protection to stop a bad BIOS from smashing beyond the object size. Unfortunately, the use of set_limit was badly botching this by setting the limit in terms of pages, when it really should have byte granularity. When doing this, I discovered my BIOS had the buggy code during the "get system device node" call: mov ax, es:[bx] Which is harmless, but has a trivial workaround.

2006-01-06[PATCH] x86: Pnp segments in segment hZachary Amsden
Move PnP BIOS segment definitions into segment.h; the segments are reserved here, so they might as well be defined here as well. Note I didn't do this for APM BIOS, as Macintosh and other systems use those values to emulate APM in some scary way I don't want to understand.

2006-01-06[PATCH] x86: GDT alignment fixZachary Amsden
Make GDT page aligned and page padded to support running inside of a hypervisor. This prevents false sharing of the GDT page with other hot data, which is not allowed in Xen, and causes performance problems in VMware. Rather than go back to the old method of statically allocating the GDT (which wastes unneded space for non-present CPUs), the GDT for APs is allocated dynamically.

However when another on the system is loaded that uses those (like drivers for serial PCMCIA), that creates a conflict for the minors.

2006-01-06[PATCH] nbd: fix TX/RX race conditionHerbert Xu
Janos Haar of First NetCenter Bt. reported numerous crashes involving the NBD driver. With his help, this was tracked down to bogus bio vectors which in turn was the result of a race condition between the receive/transmit routines in the NBD driver. The bug manifests itself like this: CPU0 CPU1 do_nbd_request add req to queuelist nbd_send_request send req head for each bio kmap send nbd_read_stat nbd_find_request nbd_end_request kunmap When CPU1 finishes nbd_end_request, the request and all its associated bio's are freed. So when CPU0 calls kunmap whose argument is derived from the last bio, it may crash. Under normal circumstances, the race occurs only on the last bio. However, if an error is encountered on the remote NBD server (such as an incorrect magic number in the request), or if there were a bug in the server, it is possible for the nbd_end_request to occur any time after the request's addition to the queuelist. The following patch fixes this problem by making sure that requests are not added to the queuelist until after they have been completed transmission. In order for the receiving side to be ready for responses involving requests still being transmitted, the patch introduces the concept of the active request. When a response matches the current active request, its processing is delayed until after the tranmission has come to a stop. This has been tested by Janos and it has been successful in curing this race condition. From: Herbert Xu <herbert@gondor.apana.org.au> Here is an updated patch which removes the active_req wait in nbd_clear_queue and the associated memory barrier. I've also clarified this in the comment.

2006-01-06[PATCH] pcmcia: properly handle static mem, but dynamic io socketsDominik Brodowski
Some PCMCIA sockets have statically mapped memory windows, but dynamically mapped IO windows. Using the "nonstatic" socket library is inpractical for them, as they do neither need a resource database (as we can trust the kernel resource database on m68k and ppc) nor lots of other features of that library. Let them get a small "iodyn" socket library (105 lines of code) instead. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2006-01-06[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ↵Dominik Brodowski
callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2006-01-05[ATYFB]: Fix onboard video on SPARC Blade 100 for 2.6.{13,14,15}Luis F. Ortiz
I have recently been switching from using 2.4.32 on my trusty old Sparc Blade 100 to using 2.6.15 . Some of the problems I ran into were distorted video when the console was active (missing first character, skipped dots) and when running X windows (colored snow, stripes, missing pixels). A quick examination of the 2.6 versus 2.4 source for the ATY driver revealed alot of changes. A closer look at the code/data for the 64GR/XL chip revealed two minor "typos" that the rewriter(s) of the code made. The first is a incorrect clock value (230 .vs. 235) and the second is a missing flag (M64F_SDRAM_MAGIC_PLL). Making both these changes seems to have fixed my problem. I tend to think the 235 value is the correct one, as there is a 29.4 Mhz clock crystal close to the video chip and 235.2 (29.4*8) is too close to 235 to make it a coincidence. The flag for M64F_SDRAM_MAGIC_PLL was dropped during the changes made by adaplas in file revision 1.72 on the old bitkeeper repository. The change relating to the clock rate has been there forever, at least in the 2.6 tree. I'm not sure where to look for the old 2.5 tree or if anyone cares when it happened. On SPARC Blades 100's, which use the ATY MACH64GR video chipset, the clock crystal frequency is 235.2 Mhz, not 230 Mhz. The chipset also requires the use of M64F_SDRAM_MAGIC_PLL in order to setup the PLL properly for the DRAM. Signed-off-by: Luis F. Ortiz <lfo@Polyad.Org> Signed-off-by: David S.
