Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

glibc expects to count lines beginning with "processor" to determine the number of processors, not lines beginning with "Processor". So, give glibc the format it expects. Signed-off-by:

We don't want to call dump_cpu_info() from cpu_init() after boot since it produces a lot of unnecessary noise - since cpu_init() gets called on resume and hotplug cpu insertion events. Signed-off-by:

Patch from Richard Purdie Update the PXA pm.c file to allow machines (such as the Sharp Zaurus) to override the standard pm functions but reuse/wrap them where needed. The init call is made slightly earlier to give machine code an init level to override them in removing any race. Signed-off-by: Richard Purdie Signed-off-by:

Patch from Nicolas Pitre Since we know the value of cpsr on entry, we can replace the bic+orr with a single eor. Also remove a possible result delay (at least on XScale). Signed-off-by:

Patch from Alessandro Zummo This patch fixes AHB/PCI endianness problems when the processor is in little-endian mode. The patch configures the CSR register closely following the directives in [1], paragraph 4.1, page 19. According to the considerations in [1], page 11, while the AHB bus supports both endian modes, on the IXP4XX it always uses big-endian. The PCI bus is connected to the South AHB. A wrong setting in the CSR register will thus cause a malfunctional PCI bus. A schematic diagram of the bus interconnections on the IXP4XX can be found in [1], page 18. The patch has been verified to work on the NSLU2 in both LE and BE modes. The author is Peter Korsgaard. [1] Intel

Include autoconf.h into every kernel compilation via the gcc command line using -imacros. This ensures that we have the kernel configuration included from the start, rather than relying on each file having #include <linux/config.h> as appropriate. History has shown that this is something which is difficult to get right. Since we now include the kernel configuration automatically, make configcheck becomes meaningless, so remove it.

my patch "x86: initialise tss->io_bitmap_owner to something" (commit ID d5cd4aad) introduced a problem with a program (DOSEMU) that called ioperm after already doing some port i/o. The problem is that a process switch return causes tss->io_bitmap_base to be set to IO_BITMAP_OFFSET so that the fault (that *really* sets the io bitmap) never triggers. This fixes that regression.

Some visually impaired people use hardware devices which directly read the vga screen. When newt for instance asks to hide the cursor for better visual aspect, the kernel puts the vga cursor out of the screen, so that the cursor position can't be read by the hardware device. This is a great loss for such people. Here is a patch which uses the same technique as CUR_NONE for hiding the cursor while still moving it. Mario, you should apply it to the speakup kernel for access floppies asap. I'll submit a 2.4 patch too. Signed-off-by: samuel.thibault@ens-lyon.org Signed-off-by:

Statically allocated devices in module data is a potential cause of oopsen. The device may be in use by a userspace process, which will keep a reference to the device. If the module is unloaded, the module data will be freed. Subsequent use of the platform device will cause a kernel oops. Use generic platform device allocation/release code in modules.

Re-jig the simple platform device support to allow private data to be attached to a platform device, as well as allowing the parent device to be set. Example usage: pdev = platform_device_alloc("mydev", id); if (pdev) { err = platform_device_add_resources(pdev, &resources, ARRAY_SIZE(resources)); if (err == 0) err = platform_device_add_data(pdev, &platform_data, sizeof(platform_data)); if (err == 0) err = platform_device_add(pdev); } else { err = -ENOMEM; } if (err) platform_device_put(pdev); Signed-off-by:

Adds a phy_mask field to struct mii_bus and uses it. This field indicates each phy address to be ignored when probing the mdio bus. This support is needed for the fs_enet and ibm_emac drivers to be converted to the generic phy layer among other drivers. Many systems lock up on probing certain phy addresses or probing doesn't return 0xffff when nothing is found at the address. A new driver I'm working on also makes use of this mask. Signed-off-by:

Some boards using the 79c976 pcnet32 chip will hang the system if the ethtool --register-dump is performed with the device operational. The request to read bcr30 is retried by the PCI device infinitely without returning data, hanging the system. Tested ia32 and ppc64. Signed-off-by:

This patch is a better fix for Allied Telesyn 2700/2701 FX boards than the change made in early January this year. It allows the user to select the speed/duplex via module_param, but if no selection is made, forces the speed to 100 FD. It fixes both Bugzilla bugs 2669 and 4551. Tested ia32 and ppc64 by myself, and by the originator of bug 2669. Signed-off-by:

Display the name eth%d or pci_name() of device which fails to allocate memory. When changing ring size via ethtool, it also releases the lock before returning on error. Added comment that the caller of pcnet32_alloc_ring must call pcnet32_free_ring on error, to avoid leak. Tested ia32 by forcing allocation errors. Signed-off-by:

Hi, This patch provides dynamic two buffer-mode and 3 buffer-mode options. Previously 2 buffer-mode was compilation option. Now with this patch applied one can load driver in 2 buffer-mode with module-load parameter ie. #insmod s2io.ko rx_ring_mode=2 This patch also provides 3 buffer-mode which provides header separation functionality. In 3 buffer-mode skb->data will have L2/L3/L4 headers and "skb_shinfo(skb)->frag_list->data" will have have L4 payload. one can load driver in 3 buffer-mode with same above module-load parameter ie. #insmod s2io.ko rx_ring_mode=3 Please review the patch.

fid is declared as a u32 (unsigned int), and then a few lines later, it is checked for a value < 0, which is clearly useless. In the two locations this function is used, in one it is *explicitly* given a negative number, which would be ignored with the current definition. Thanks to LinuxICC (http://linuxicc.sf.net).
