obviously FC Port Speeds in scsi_transport_fc.h are defined according to FC-HBA: #define FC_PORTSPEED_1GBIT 1 #define FC_PORTSPEED_2GBIT 2 #define FC_PORTSPEED_10GBIT 4 #define FC_PORTSPEED_4GBIT 8 Problem is, whoever invented FC-HBA did not care about FC-FS or FC-GS-x. Following FC-FS/FC-GS-x defintions of port speeds would look like: 1 GBit: 0x0001 2 GBit: 0x0002 4 GBit: 0x0004 10GBit: 0x0008 (and new in FC-LS: 8 Gbit: 0x0010 16GBit: 0x0020) I really appreciate if scsi_transport_fc.h would define port speeds according to FC-GS-x/FC-FS. Thus mapping of port speed capabilities to values defined in scsi_transport_fc.h can be avoided in the LLDD. Attached is a patch to change the definitions.

NET/ROM is lacking a connection reset like TCP's RST flag which at times may result in a connecting having to slowly timing out instead of just being reset. An earlier attempt to reset the connection by sending a NR_CONNACK | NR_CHOKE_FLAG transport was inacceptable as it did result in crashes of BPQ systems. An alternative approach of introducing a new transport type 7 (NR_RESET) has be implemented several years ago in Paula Jayne Dowie G8PZT's Xrouter. Implement NR_RESET for Linux's NET/ROM but like any messing with the state engine consider this experimental for now and thus control it by a sysctl (net.netrom.reset) which for the time being defaults to off.

As noted by matz@suse.de The problem is, that on i386 the syscallN macro is defined like so: long __res; \ __asm__ volatile ("int $0x80" \ : "=a" (__res) \ : "0" (__NR_##name),"b" ((long)(arg1)),"c" ((long)(arg2)), \ "d" ((long)(arg3)),"S" ((long)(arg4)),"D" ((long)(arg5))); \ If one of the arguments (in the _llseek syscall it's the arg4) is a pointer which the syscall is expected to write to (to the memory pointed to by this ptr), then this side-effect is not captured in the asm. If anyone uses this macro to define it's own version of the syscall (sometimes necessary when not using glibc) and it's inlined, then GCC doesn't know that this asm write to "*dest", when called like so for instance: out = 1; llseek (fd, bla, blubb, &out, trara) use (out); Here nobody tells GCC that "out" actually is written to (just a pointer to it is passed to the asm). Hence GCC might (and in the above bug did) copy-propagate "1" into the second use of "out". The easiest solution would be to add a "memory" clobber to the definition of this syscall macro. As this is a syscall, it shouldn't inhibit too many optimizations. Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

The generic TLB flush functions kept upto 506 pages per CPU to avoid too frequent IPIs. This value was done for the L1 cache of older x86 CPUs, but with modern CPUs it does not make much sense anymore. TLB flushing is slow enough that using the L2 cache is fine. This patch increases the flush array on x86-64 to cache 5350 pages. That is roughly 20MB with 4K pages. It speeds up large munmaps in multithreaded processes on SMP considerably. The cost is roughly 42k of memory per CPU, which is reasonable. I only increased it on x86-64 for now, but it would probably make sense to increase it everywhere. Embedded architectures with SMP may keep it smaller to save some memory per CPU. Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Instead of using a global spinlock to protect the state of the remote TLB flush use a lock and state for each sending CPU. To tell the receiver where to look for the state use 8 different call vectors. Each CPU uses a specific vector to trigger flushes on other CPUs. Depending on the received vector the target CPUs look into the right per cpu variable for the flush data. When the system has more than 8 CPUs they are hashed to the 8 available vectors. The limited global vector space forces us to this right now. In future when interrupts are split into per CPU domains this could be fixed, at the cost of needing more IPIs in flat mode. Also some minor cleanup in the smp flush code and remove some outdated debug code. Requires patch to move cpu_possible_map setup earlier.

In particular on systems where the local APIC space and node space is very different from the Linux CPU number space. Previously the older NUMA setup code directly parsing the K8 northbridge registers had some issues on 8 socket or dual core systems. This patch fixes them. This is mainly done by fixing some confusion between Linux CPU numbers and local APIC ids. We now pass the local APIC IDs to later code, which avoids mismatches. Also add some heuristics to detect cases where the Hypertransport nodeids and the local APIC IDs don't match, but are shifted by a constant offset. This is still all quite hackish, hopefully BIOS writers fill in correct SRATs instead. Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>
