Hp is providing a Hardware WatchDog Timer driver that will only work with the specific HW Timer located in the HP ProLiant iLO 2 ASIC. The iLO 2 HW Timer will generate a Non-maskable Interrupt (NMI) 9 seconds before physically resetting the server, by removing power, so that the event can be logged to the HP Integrated Management Log (IML), a Non-Volatile Random Access Memory (NVRAM). The logging of the event is performed using the HP ProLiant ROM via an Industry Standard access known as a BIOS Servic...

First, rename ac/av to argc/argv; those are pretty conventional names. Second, switch from doing our own parsing of command line arguments to using getopt(3) to do it. Aside from simplifying things, this allows us to specify multiple arguments; the old code could only accept two arguments (input_mode and kconfig name). Note some subtle changes: - The argument '-?' is no longer supported. - '-h' is not treated as an error, so output goes to stdout, and we exit with '0'. - There is no comp...

Hum... did you test your patch with many routes declared ? (more than 32 on i386/x86_64) 127 is not a random value, but chosen as a power of two minus 1. PAGE_SIZE is garanted to be a multiple of 128 (127 chars + line_feed) on all arches. So each read() on /proc/net/route delivers PAGE_SIZE/128 lines. With your patch, some lines might be truncated (one every 32 on i386) -

Fix mprotect bug in recent commit 3ed75eb8f1cd89565966599c4f77d2edb086d5b0 (setup vma->vm_page_prot by vm_get_page_prot()): the vma_wants_writenotify case was setting the same prot as when not. Nothing wrong with the use of protection_map[] in mmap_region(), but use vm_get_page_prot() there too in the same ~VM_SHARED way.

Change the page member of the scatterlist structure to be an unsigned long, and encode more stuff in the lower bits: - Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located at sg + 1. - Bit 0 set: this is a chain entry, the next real entry is at ->page_link with the two low bits masked off. - Bit 1 set: this is the final entry in the sg entry. sg_next() will return NULL when passed such an entry. It's thus important that sg table users use the proper accessors to get a...

Better make sure that such alignment never happens... But no, I don't think it will, since these things would generally always have to be allocated with an allocator, and the *allocator* won't return 2-byte aligned data structures. Linus -

Well, quite frankly, equally easy is to just add a __attribute__((aligned(4))) or whatever the gcc syntax for that is today.. That guarantees that gcc lays things out properly. Linus -

You still do need one bit for the discontiguous case, so it's not like you can avoid the hacks anyway (unless you just blow up the structure entirely) and make it a separate member). So once you have that bit+pointer, using a separate NULL entry isn't exactly prettier. Especially as we actally want to see the difference between "end-of-allocation" and "not yet filled in", so you shouldn't use NULL anyway, you should probably use something like "all-ones". Linus -

It'll mean m-1 scatterlists fit on a slab. -- Mathematics is the supreme nostalgia of our time. -

Yes. Especially if m is 2 or 1. A scatterlist on 64-bit x86 looks like it takes 32 bytes, which means 128 elements fit on a page. One more spills - ouch! But maybe chaining means this doesn't matter any more. Maybe we can even pick a nice moderate sg size and reduce the number of mempools we need for these things. -- Mathematics is the supreme nostalgia of our time. -

Also, the current version of SLOB will return objects aligned at 2 bytes if the I'm guessing the extra entry makes slab-like allocators unhappy. -- Mathematics is the supreme nostalgia of our time. -

One of the systems tested in autoboot crashes at boot with with -git22. This is a AMD 2 socket Opteron NUMA system.

Sorry was a mistake (cue: there is no 2.6.23-git22 yet). It turned out to be an old broken kernel. Current -git seems to boot. Sorry for the noise. -Andi -

Right. As was pointed in previous email the bug was introduced in post 2.6.23 updates (I was running git but Makefile version was still 2.6.23). Looks like we have a fix that'll go to Linus shortly. I'll go back to released Same model I have, BTW. Thanks Parag -
