* [TTY]: Fix network driver interactions with TCGET/SET calls.Alan Cox2007-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Dave Miller noted various cases where line disciplines for things like ppp go poking around in termios themselves in ways that broke with the new termios code. Rather than have them all learning about termios internals provide proper methods for this - tty_mode_ioctl() This handles all the terminal mode handling for speed/carrier etc and none of the methods are ldisc dependant so they can be called by any user - tty_perform_flush() This extracts the flush functionality and enables pppd the ppp layer to share it cleanly. The existing n_tty_ioctl code is refactored in this patch to provide the new functions and to call them itself appropriately. This patch has no (intended) behaviour changes and simply prepares for the other fixes. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV4]: Compact some ifdefs in the fib code.Pavel Emelyanov2007-11-07

* [NET]: Define infrastructure to keep 'inuse' changes in an efficent SMP/NUMA ↵Eric Dumazet2007-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | way. "struct proto" currently uses an array stats[NR_CPUS] to track change on 'inuse' sockets per protocol. If NR_CPUS is big, this means we use a big memory area for this. Moreover, all this memory area is located on a single node on NUMA machines, increasing memory pressure on the boot node. In this patch, I tried to : - Keep a fast !CONFIG_SMP implementation - Keep a fast CONFIG_SMP implementation for often used protocols (tcp,udp,raw,...) - Introduce a NUMA efficient implementation Some helper macros are defined in include/net/sock.h These macros take into account CONFIG_SMP If a "struct proto" is declared without using DEFINE_PROTO_INUSE / REF_PROTO_INUSE macros, it will automatically use a default implementation, using a dynamically allocated percpu zone. This default implementation will be NUMA efficient, but might use 32/64 bytes per possible cpu because of current alloc_percpu() implementation. However it still should be better than previous implementation based on stats[NR_CPUS] field. When a "struct proto" is changed to use the new macros, we use a single static "int" percpu variable, lowering the memory and cpu costs, still preserving NUMA efficiency.

* [IPV4]: Clean the ip_sockglue.c from some ugly ifdefsPavel Emelyanov2007-11-07
| | | | | | | | | | | The #idfed CONFIG_IP_MROUTE is sometimes places inside the if-s, which looks completely bad. Similar ifdefs inside the functions looks a bit better, but they are also not recommended to be used. Provide an ifdef-ed ip_mroute_opt() helper to cleanup the code.

| * libata and bogus LBA48 drivesGeert Uytterhoeven2007-11-04
| | | | | | | | | | | | | | | | | | | | | | | | A colleague noticed recent versions of Ubuntu no longer detect his 80 GB ST380020ACE drive. This drive is special in that it advertises LBA48 support, but has the lba_capacity_2 field set to zero (cfr. http://lkml.org/lkml/2004/3/30/163). Upon closer look, libata indeed doesn't seem to handle this case yet. Below is an (untested) fix. Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A reasonably common problem with some devices is that they will disable MSI generation when the INTX_DISABLE bit is set in the PCI_COMMAND register. Quirk this explicitly, guarding the pci_intx() calls in msi.c with this quirk indication. The first entries for this quirk are for 5714 and 5780 Tigon3 chips, and thus we can remove the workaround code from the tg3.c driver. Signed-off-by: David S.

An earlier commit to fix the problem: e3008dedff4bdc96a5f67224cd3d8d12237082a0: "PCI: disable MSI by default on systems with Serverworks HT1000 chips" was not entirely correct, and has been reverted. MSI does not work on the PCIX bus because the BIOS did not set the HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the bridge. We use the existing quirk_msi_ht_cap() to detect the problem and disable MSI in all buses behind it.

I dug into the git repository and I believe this bug was added with this commit (104b8deaa5c0144cccfc7d914413ff80c7176af1); 2006-03-27 KAMEZAWA Hiroyuki [PATCH] unify pfn_to_page: sh pfn_to_page -#define phys_to_page(phys) (mem_map + (((phys)-__MEMORY_START) >> PAGE_SHIFT)) -#define page_to_phys(page) (((page - mem_map) << PAGE_SHIFT) + __MEMORY_START) +#define phys_to_page(phys) (pfn_to_page(phys >> PAGE_SHIFT)) +#define page_to_phys(page) (page_to_pfn(page) << PAGE_SHIFT) Reported-by: David ADDISON <david.addison@st.com> Reported-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | | | libata: increase 128 KB / cmd limit for ATAPI tape drivesTony Battersby2007-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are limited in the amount of data that they can transfer by the max_sectors value. The max_sectors value is currently calculated according to the command set for disk drives, which doesn't apply to tape drives. The default max_sectors value of 256 limits ATAPI tape drive commands to 128 KB. This patch against 2.6.24-rc1 increases the max_sectors value for tape drives to 65535, which permits tape drive commands to transfer just under 32 MB. Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V SATA tape drive. Note that some of the chipset drivers also set their own max_sectors value, which may override the value set in libata-core. I don't have any of these chipsets to test, so I didn't go messing with them. Also, ATAPI devices other than tape drives may benefit from similar changes, but I have only tape drives and disk drives to test.

* | | | Use i8253.c lock for PC speaker on MIPS, too.Ralf Baechle2007-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Jazz machines have to use the PIT timer for dyntick and highresolution kernels. This may break because currently just like i386 used to do MIPS uses two separate spinlocks in the actual PIT code and the PC speaker code. So switch to do it the same that x86 currently does PIT locking. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

A MIPS system may not have a PIT by the symbol is used all over the kernel including some APIs. So keeping it defined to the number for the PIT is the only sane thing for now.
