This patch adds some PCI Express register constants to <linux/pci.h> For my device, setting the Max_Read_Request_Size value in the PCI Express device control register makes a huge performance difference. I wanted my driver code that does this to be a little more self-documenting than: pci_read_config_word(mdev->pdev, cap + 8, &val); val = (val & ~(5 << 12)) | (5 << 12); I went a little overboard and added all the basic device register fields. If desired I could go even further overboard and add the link, slot and root registers as well. This patch is based on Matthew Wilcox's patch for pciutils, corrected for some PCI Express spec 1.0a changes.

On i386 it's in include/asm-i386/setup.h On x86_64 it belongs in include/asm-x86_64/bootsetup.h. Patch below defines EDD_MBR_SIG_NR and EDD_MBR_SIGNATURE on x86_64.

Current 2.6.7 tree acts as if it is alway under memory pressure because a recent change did a s/tcp_memory_pressure/tcp_prot.memory_pressure/. The problem is tcp_prot.memory_pressure is a pointer, so it is always non-zero! Rather than using *tcp_prot.memory_pressure, just go back to looking at tcp_memory_pressure.

'strace' shows a problem with a missing release_task for self-reaping clones that have been traced. We need to defer releasing them until the tracer is done with them, but if the tracer dies, we need to handle that case gracefully too. We do that by having 'forget_original_parent()' generate a list of tasks to release when this case happens. Patch based on discussions on linux-kernel, and suggestions from Roland McGrath <roland@redhat.com>.

This fixes a corner-case NX bug: the x86 SMP kernel doesnt boot on SMP Opterons if NX is enabled [and mem=nopentium is specified], due to kernel-space NX protection preventing the SMP trampoline from being executable. Since the SMP trampoline is a rare case of 'dynamic code' executed by the kernel (it has to be below 640K so it cannot be part of the kernel text itself), i've added the necessary infrastructure to enable/disable executability of specific kernel pages. We cannot simply disable NX via the MSR because we've got the NX bits in the kernel pagetables, which are set up before we do the SMP bootup. The NX bit in the pagetables is undefined if EFER.NXE is 0, so we cannot count on NX-capable CPUs not faulting when they encounter them. I've tested the x86 kernel on a non-NX SMP x86 box and on an NX UP box, on which i've also tested a simulated SMP trampoline, it all works fine. - add infrastructure to enable/disable executability of kernel pages - make the SMP trampoline page executable.

This is a rather old patch which re-orders the teardown of PCMCIA network devices. Current device drivers remove the IO mappings, interrupts, and free any PCMCIA windows before they unregister themselves from the network layer. This patch ensures that we first unregister from the network layer before performing any teardown of resources or windows. Note: the only card which has been tested in this patch is pcnet_cs.

Several network drivers have checks that they are only built with -O. This breaks checking with sparse and other tools, and seems like a holdover from when drivers were built out of tree and the kernel build system was less stable. This patch gets rid of these.

This started out from sparse warnings about calling with fddi_broadcast that is declared const. This fixes that and gets rid of some of the namespace pollution of this driver by moving the predicate function is_individual, is_broadcast, ... as inline's in the one file that uses them.

Change the pcnet32 driver to use module_param and module_param_array.

The pcnet32 driver was not correctly enabling MII autonegotiation after booting when ppc firmware forced the speed/duplex mode of the chip. After several conversations with AMD this patch corrects the problem. I have tested this on hardware I have available (ia32 and ppc64) but I would like wider audience testing of this patch.

A recent change I made broke pcnet32 in a way that allowed real hardware to work, but broke VMWare. This patch acknowledges all interrupts early in the pcnet32_interrupt while loop. Without this patch on real hardware the first transmit operation would clear the 'init' interrupt, but in VMWare it would rain interrupts. Keith Moore did more testing for me on VMWare and I did a better job testing on hardware. Petr Vandrovec correctly pointed out the source of the problem on lkml. This patch is not needed for 2.4.27-rc1 unless my patch labeled "pcnet32: recover after rx hang" is applied (which it has not). signed-off-by: Don Fry <brazilnut@us.ibm.com>
