From: "Jon Thackray" <jgt@pobox.com> * Lowered priority of "too many keys" message in drivers/input/keyboard/atkbd.c This fixes Debian BTS #239036. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=239036 The keyboard under 2.6.4 seems to be behaving strangely, reporting unknown key codes and too many keys pressed, even when no keys have been pressed. The keyboard is connected via an 8 way KVM switch, but was working quite acceptably under 2.4.25 with no such messages. Trying 2.6.3 is not an option as it doesn't support the hardware properly, as previously reported. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Using the vga console driver, if the number of the lines scrolled out is less than four, then Shift+PageUp doesn't work. The bug is closely related to the 'margin' feature of scrolling, which means that if less than four lines should remain unvisible in the direction we are scrolling to, then we scroll a little bit more just to see those few lines. Kind of two small magnets at the borders of the buffer. This bug was also reported with maybe a less clear description by Stepan Koltsov (cc'ed just for fun) back in 2001 and he got no answer. I found it at http://seclists.org/lists/linux-kernel/2001/Nov/0080.html His patch simply disables margin support and hence everythings becomes okay, but you lose a nice feature. Here's a patch that retains margin support and fixes the bug. Works for me, tested for a week. No guarantee. As I don't fully understand the code (see also my previous mail) I'm not 100% sure that I'm doing the right thing, so I'd prefer if someone would take a closer look at it. At least 2.4 and 2.6 are affected, maybe older ones too. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

The epoll allocation for the fd lookup hash used to allocate up to 1MB (depending on the "hint" size passed to epoll_create()) with __get_free_pages(0), and this might lead to a "malicious" user to do something like: for (i = 0; i < 1024; i++) epoll_create(BIG-NUM); You can replace "malicious user" with IBM-ltp test suite, and the meaning does not change. The above code might exhaust memory badly, even before the file creation limit is topped. Also, the allocation was independent from the number of fds pushed into the epoll fd hash. Using an rb-tree ther will be not pre-allocation of the hash, and the size of the memory used will be proportional to the number of fds pushed into the epoll fd. The patch also removes 100 lines of code, that is never a bad thing ;) Signed-off-by: Davide Libenzi <davidel@xmailserver.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Judging from context, I think there's a misplaced "&" in this code that can cause stack overflows and other nasty problems. Perhaps it's left over from when msgdata was an array instead of a pointer? Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

It decreases stack consumption in one of ncpfs's paths from 3000 to 2200 bytes (and stack portion in ncpfs ioctl code from 1336 to 452 bytes). - some code used large structure (with embeded 256 bytes for filename) while it never passed filename around. Use something smaller in ncp_conn_logged_in. Decrease 616 => 300. - gcc-3.3 is very bad when it comes to parallel blocks in ioctl. Split some branches from large switch to separate functions. ncp_ioctl now uses 152 bytes of stack (instead of 720) and biggest child 64.

The 'unplug on queued exceeding unplug threshold' logic only works for file system requests currently, since it's in __make_request(). Move it where it belongs, in elv_add_request().

This patch provides a conversion routine for 32-bit user space apps that call into a 64-bit kernel on x86_64 architectures. This is required for the HP Array Configuration utility and the HP management agents. Without this patch the apps will not function. The 2 ioctls affected are the cciss pass thru ioctls. Caveat: it spits out 2 warnings during compilation. I've tried everything I can think of to clean them up, but... If anyone has any helpful suggestions I'm all ears.

Due to different structure alignment rules in the ABI between ia32 and ia64, certain members of the dirent structure are not guaranteed to be 8 byte aligned on ia64. This requires a compat wrapper around these 32 bit system calls. Other architectures may or may not have the problem, depending on the alignment rules. This was observed by running /emul/ia32-linux/bin/ls on 2.6.6 which produces kernel mode unaligned faults.

- "\<" and "\>" can be safely replaced with "<" and ">" - "$var =~ /^string$/" is better written "$var eq 'string'" - $i is better written without the double quotes - it's not safe to use for without "my"ing the iteration variable - "print foreach @array" is better written "print @array" - declare variables - ".*" is useless at the end of a regexp - "$a[@A] = $foo" is a rather obfuscated syntax for "push @A, $foo"... let's not opencoding language basic operators... - ignoring return value from a regexp is very bad: this can results in working on previous value of $1, $2, ...

Suggested by Manfred Spraul. __get_free_pages had a hack to do node interleaving allocation at boot time. This patch sets an interleave process policy using the NUMA API for init and the idle threads instead. Before entering the user space init the policy is reset to default again. Result is the same. Advantage is less code and removing of a check from a fast path. Removes more code than it adds. I verified that the memory distribution after boot is roughly the same.

While sweeping the APIC code two points were missed. The first is getting the definition of BAD_APICID available to include/asm-i386/mach-default/mach_apic.h by #including the right header, and the second is UP local APIC without UP IO-APIC linking in get_broadcast_physid().

Marking invalid APIC ID's in phys_cpu_present_map was intended to generate "collisions" between APIC ID's in order to assist the ordinary bounds checking against the broadcast physical APIC ID. However, this is bounds checked everywhere it's necessary, and it's also not even possible to properly bounds-check everywhere. So this patch removes that marking of non-present physical APIC ID's.

The following patch repairs kicking of non-present cpus by making cpu_present_to_apicid() bounds-check its argument. It also corrects the same issue on NUMA-Q by correctly passing the generated artificial APIC ID instead of the raw value discovered in the MP table. A miscellaneous compilefix for CONFIG_ACPI_BOOT is also included for completeness. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

The following patch appears sound according to an audit to ensure that all of the codepaths where it was introduced were called after the APIC fixmappings were set up. This patch introduces get_physical_broadcast(), which checks the version ID of the local APIC to determine whether it's a serial APIC or xAPIC, and returns the correct physical broadcast ID. It replaces all uses of APIC_BROADCAST_ID and IO_APIC_MAX_ID with this in order to ensure. It also changes the checks during MP table parsing so the APIC ID is checked in tandem with the version number. I'm holding out for some kind of testing to get an idea of whether this covers the cases or introduces regressions, or whatever.
