* add CONFIG_VT_UNICODEBill Nottingham2007-10-17
| | | | | | | | | | | | | | | | | | As of now, the kernel defaults to non-unicode and XLATE for the keyboard. We've been changing this in Fedora, but that requires patching the defaults in the kernel. The attached introduces CONFIG_VT_UNICODE, which sets the console in unicode mode by default on boot, including both the virtual terminal and the keyboard driver.

* unicode diacritics supportSamuel Thibault2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There have been issues with non-latin1 diacritics and unicode. http://bugzilla.kernel.org/show_bug.cgi?id=7746 Git 759448f459234bfcf34b82471f0dba77a9aca498 `Kernel utf-8 handling' partly resolved it by adding conversion between diacritics and unicode. The patch below goes further by just turning diacritics into unicode, hence providing better future support. The kbd support can be fetched from http://bugzilla.kernel.org/attachment.cgi?id=12313 This was tested in all of latin1, latin9, latin2 and unicode with french and czech dead keys. Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR. New function int conv_uni_to_8bit(u32 uni) for converting unicode into 8bit _input_. No, we don't want to store the translation, as it is potentially sparse and large.

| | | | | | | | | | | | | | | | Driver does proc_mkdir("ipmi", NULL); but remove_proc_entry(proc_ipmi_root->name, &proc_root); This is OK and working if only slightly inconsistent.

* vt/vgacon: Check if screen resize request comes from userspaceAntonino A. Daplas2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | Various console drivers are able to resize the screen via the con_resize() hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that con_resize() of the VGA console will always return success even if the resulting screen is not compatible with the hardware. However, this particular behavior of the VGA console, as reported in Kernel Bugzilla Bug 7513, can cause undefined behavior if the user starts with a console size larger than 80x25. To work around this problem, add an extra parameter to con_resize(). This parameter is ignored by drivers except for vgacon. If this parameter is non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl and vgacon will always return success. If this parameter is zero, vgacon will return -EINVAL if the requested size is not compatible with the hardware. The latter is the more correct behavior. With this change, SVGATextMode should still work correctly while in-kernel and stty resize calls can expect correct behavior from vgacon.

* remove ZERO_PAGENick Piggin2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit b5810039a54e5babf428e9a1e89fc1940fabff11 contains the note A last caveat: the ZERO_PAGE is now refcounted and managed with rmap (and thus mapcounted and count towards shared rss). These writes to the struct page could cause excessive cacheline bouncing on big systems. There are a number of ways this could be addressed if it is an issue. And indeed this cacheline bouncing has shown up on large SGI systems. There was a situation where an Altix system was essentially livelocked tearing down ZERO_PAGE pagetables when an HPC app aborted during startup. This situation can be avoided in userspace, but it does highlight the potential scalability problem with refcounting ZERO_PAGE, and corner cases where it can really hurt (we don't want the system to livelock!). There are several broad ways to fix this problem: 1. add back some special casing to avoid refcounting ZERO_PAGE 2. per-node or per-cpu ZERO_PAGES 3. remove the ZERO_PAGE completely I will argue for 3. The others should also fix the problem, but they result in more complex code than does 3, with little or no real benefit that I can see. Why? Inserting a ZERO_PAGE for anonymous read faults appears to be a false optimisation: if an application is performance critical, it would not be doing many read faults of new memory, or at least it could be expected to write to that memory soon afterwards. If cache or memory use is critical, it should not be working with a significant number of ZERO_PAGEs anyway (a more compact representation of zeroes should be used). As a sanity check -- mesuring on my desktop system, there are never many mappings to the ZERO_PAGE (eg. 2 or 3), thus memory usage here should not increase much without it. When running a make -j4 kernel compile on my dual core system, there are about 1,000 mappings to the ZERO_PAGE created per second, but about 1,000 ZERO_PAGE COW faults per second (less than 1 ZERO_PAGE mapping per second is torn down without being COWed). So removing ZERO_PAGE will save 1,000 page faults per second when running kbuild, while keeping it only saves less than 1 page clearing operation per second. 1 page clear is cheaper than a thousand faults, presumably, so there isn't an obvious loss. Neither the logical argument nor these basic tests give a guarantee of no regressions. However, this is a reasonable opportunity to try to remove the ZERO_PAGE from the pagefault path. If it is found to cause regressions, we can reintroduce it and just avoid refcounting it. The /dev/zero ZERO_PAGE usage and TLB tricks also get nuked. I don't see much use to them except on benchmarks. All other users of ZERO_PAGE are converted just to use ZERO_PAGE(0) for simplicity. We can look at replacing them all and maybe ripping out ZERO_PAGE completely when we are more satisfied with this solution.

The problem is this: If "entry = kzalloc(sizeof(struct amd_page_map), GFP_KERNEL);" fails, then there's a loop in the function to free all entries allocated so far and break out of the allocation loop. That in itself is pretty sane, but then the (now freed) 'tables' is assigned to amd_irongate_private.gatt_pages and 'retval' is set to -ENOMEM which causes amd_free_gatt_pages(); to be called at the end of the function. The problem with this is that amd_free_gatt_pages() will then loop 'amd_irongate_private.num_tables' times and try to free each entry in tables[] - this is bad since tables has already been freed and furthermore it will call kfree(tables) at the end - a double free. This patch removes the freeing loop in amd_create_gatt_pages() and instead relies entirely on the call to amd_free_gatt_pages() to free everything we allocated in case of an error. It also sets amd_irongate_private.num_tables to the actual number of entries allocated instead of just using the value passed in from the caller - this ensures that amd_free_gatt_pages() will only attempt to free stuff that was actually allocated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Now we will only have entries in the device tree for the actual existing devices (including their OS/400 properties). This way viotape.c gets all the information about the devices from the device tree. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was only being used to carry around dma_iommu_ops and vio_iommu_table which we can use directly instead. This also means that vio_bus_device doesn't need to refer to them either.

* | | | | | | drivers/firmware: const-ify DMI API and internalsJeff Garzik2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.

* | | | | | | Correct Makefile rule for generating custom keymapMaarten Bressers2007-10-08

Stop. make[1]: *** [drivers/char] Error 2 make: *** [drivers] Error 2 This was caused by commit af8b128719f5248e542036ea994610a29d0642a6, which deleted a necessary colon from the Makefile rule that generates the keymap, since that rule contains both a target and a target-pattern.

* | | | | | | VT_WAITACTIVE: Avoid returning EINTR when not necessaryLinus Torvalds2007-10-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should generally prefer to return ERESTARTNOHAND rather than EINTR, so that processes with unhandled signals that get ignored don't return EINTR. This can help with X startup issues: Fatal server error: xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call although the real fix is having the X server always retry EINTR regardless (since EINTR does happen for signals that have handlers installed). Keithp has a patch for that. Regardless, ERESTARTNOHAND is the correct thing to use. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
