* [TG3]: Speed up SRAM access (2nd version)Michael Chan2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | | Speed up SRAM read and write functions if possible by using MMIO instead of config. cycles. With this change, the post reset signature done at the end of D3 power change must now be moved before the D3 power change. IBM reported a problem on powerpc blades during ethtool self test that was caused by the memory test taking excessively long. Config. cycles are very slow on powerpc and the memory test can take more than 10 seconds to complete using config. cycles. David Miller informed me that an earlier version of the patch caused problems on sparc64 systems with built-in tg3 chips. This version fixes the problem by excluding all SUN built-in tg3 chips from doing MMIO SRAM access. TG3_FLAG_EEPROM_WRITE_PROT is also set unconditionally when TG3_FLG2_SUN_570X is set. This should be sane as all SUN chips are built-in and do not require Vaux switching. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* [IRDA]: smcinit merged into smsc-ircc driverLinus Walleij2006-04-10
| | | | | | | | | | | | | | This patch integrates the smcinit code into the smsc-ircc driver. Some laptops have their smsc-ircc chip not properly configured by the BIOS and needs some preconfiguration. Currently, this can be done from userspace with smcinit, a utility that comes with the irda-utils package. It messes with ioports and PCI settings, from userspace. Now with this patch, if we happen to be on one of the known to be faulty laptops, we preconfigure the chip from the driver.

* [INET]: Move no-tunnel ICMP error to tunnel4/tunnel6Herbert Xu2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the sending of ICMP messages when there are no IPv4/IPv6 tunnels present to tunnel4/tunnel6 respectively. Please note that for now if xfrm4_tunnel/xfrm6_tunnel is loaded then no ICMP messages will ever be sent. This is similar to how we handle AH/ESP/IPCOMP. This move fixes the bug where we always send an ICMP message when there is no ip6_tunnel device present for a given packet even if it is later handled by IPsec. It also causes ICMP messages to be sent when no IPIP tunnel is present. I've decided to use the "port unreachable" ICMP message over the current value of "address unreachable" (and "protocol unreachable" by GRE) because it is not ambiguous unlike the other ones which can be triggered by other conditions. There seems to be no standard specifying what value must be used so this change should be OK. In fact we should change GRE to use this value as well. Incidentally, this patch also fixes a fairly serious bug in xfrm6_tunnel where we don't check whether the embedded IPv6 header is present before dereferencing it for the inside source address.

* [NETFILTER]: Fix fragmentation issues with bridge netfilterPatrick McHardy2006-04-10
| | | | | | | | | | The conntrack code doesn't do re-fragmentation of defragmented packets anymore but relies on fragmentation in the IP layer.

* Move request_standard_resources() back to before PCI probingLinus Torvalds2006-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This effectively undoes the PCI resource allocation changes done in commit b408cbc704352eccee301e1103b23203ba1c3a0e, but leaves the cleanups of that commit in place. We're going back to marking the resources reported by e820 busy _before_ doing PCI probing, so that any PCI resource that clashes with the BIOS- reported memory map will be reloacted to a non-clashing area. The reason? Larry Finger reports that his laptop has the cardbus controller set up by the BIOS so that it conflicts with the e820 memory map, and needs to be relocated. See http://bugzilla.kernel.org/show_bug.cgi?id=6337 for more details. We'll have to work out how to handle the fbcon problem that caused that commit in the first place in some other way.

* [PATCH] x86_64: Plug GS leak in arch_prctl()John Blackwood2006-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In linux-2.6.16, we have noticed a problem where the gs base value returned from an arch_prtcl(ARCH_GET_GS, ...) call will be incorrect if: - the current/calling task has NOT set its own gs base yet to a non-zero value, - some other task that ran on the same processor previously set their own gs base to a non-zero value. In this situation, the ARCH_GET_GS code will read and return the MSR_KERNEL_GS_BASE msr register. However, since the __switch_to() code does NOT load/zero the MSR_KERNEL_GS_BASE register when the task that is switched IN has a zero next->gs value, the caller of arch_prctl(ARCH_GET_GS, ...) will get back the value of some previous tasks's gs base value instead of 0. Change the arch_prctl() ARCH_GET_GS code to only read and return the MSR_KERNEL_GS_BASE msr register if the 'gs' register of the calling task is non-zero. Side note: Since in addition to using arch_prctl(ARCH_SET_GS, ...), a task can also setup a gs base value by using modify_ldt() and write an index value into 'gs' from user space, the patch below reads 'gs' instead of using thread.gs, since in the modify_ldt() case, the thread.gs value will be 0, and incorrect value would be returned (the task->thread.gs value). When the user has not set its own gs base value and the 'gs' register is zero, then the MSR_KERNEL_GS_BASE register will not be read and a value of zero will be returned by reading and returning 'task->thread.gs'. The first patch shown below is an attempt at implementing this approach. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | If the HPET timer is enabled, the clock can drift by ~3 seconds a day.

* [PATCH] i386: Consolidate modern APIC handlingAndi Kleen2006-04-09
| | | | | | | | | | | | | | | | | | | | | | | AMD systems have a modern APIC that supports 8 bit IDs, but don't have a XAPIC version number. Add a new "modern_apic" subfunction that handles this correctly and use it (nearly) everywhere where XAPIC is tested for. I removed one wart: the code specified that external APICs would use an 8bit APIC ID. But I checked a real 82093 data sheet and it says clearly that they only use 4bit. So I removed this special case since it would a bit awkward to implement now. I removed the valid APIC tests in mptable parsing completely. On any modern system they only check against the full field width (8bit) anyways and are no-ops. This also fixes them doing the wrong thing on >8 core Opterons. This makes i386 boot again on 16 core Opterons. Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
