This patch adds efficeon as a cpu option, and makes a small update to the transmeta cpuid code. (i wasn't sure if the various doc files are UTF-8... if they are, then the e should be a U-275 ;) The compile options may not be ideal, but they're probably close. i used -march=pentium3, but -march=pentium4 would have been good enough too. The cpuid update teaches transmeta.c about the extended processor revision present in cpuid level 0x80860002... the external documentation does not indicate how to break apart this field, and instructs only that the 32-bit value should be printed in hex (alas).

I've noticed that under specific circumstances the "console=" kernel parameter is ignored. This happens when EARLY_PRINTK is enabled and the serial console is the only available. In this case unregister_console() when called for the early console sets preferred_console back to -1 replacing the value that was recorded by console_setup() -- the order of calls is as follows: 1. register_console() -- for the early console, 2. console_setup() -- recording the console index for the real console, 3. unregister_console() -- for the early console, erasing the console index recorded above, 4. register_console() -- for the real console, picking up the first device available, instead of the selected one. I've observed this problem with a DECstation system using ttyS3 -- its default console device from the firmware's point of view. The solution is to restore the setting of "console=" upon unregister_console(). This made a snapshot of 2.4.26 work for me. I wasn't able to test the changes with 2.6 because DECstation drivers don't support it yet, but the code responsible for console selection appears functionally the same. So I've concluded it needs the same change. Here's a patch. Signed-off-by:

At the moment, the NLM cookie length is fixed to 8 bytes, while 1024 is the theoretical maximum. FreeBSD uses 16 bytes, Mac OS X uses 20 bytes. Therefore we need to make the length dynamic (which I set to 32 bytes). This patch is based on an old patch for Linux 2.4.23-pre9, which I changed to patch properly (also added some stylish NIPQUAD fixes). From: Neil Brown <neilb@cse.unsw.edu.au> Further lockd tidyups. - NIPQUAD everywhere that is appropriate - use XDR_QUADLEN in more places as appropriate - discard QUADLEN which is a lockd-specific version of XDR_QUADLEN Signed-off-by:

Attached is a patch that fixes the fragmentation that Badri noticed with kmem_cache_alloc_node. kmem_cache_alloc_node tries to allocate memory from a given node. The current implementation contains two bugs: - the node aware code was used even for !CONFIG_NUMA systems. Fix: inline function that redefines kmem_cache_alloc_node as kmem_cache_alloc for !CONFIG_NUMA. - the code always allocated a new slab for each new allocation. This caused severe fragmentation. Fix: walk the slabp lists and search for a matching page instead of allocating a new page. - the patch also adds a new statistics field for node-local allocs. They should be rare - the codepath is quite slow, especially compared to the normal kmem_cache_alloc. Signed-Off-By:

There is a useless AND in swp_type() function. We just shifted right SWP_TYPE_SHIFT() bits the value from the swp_entry_t, and then we AND it with "(1 << 5) - 1" (which is a mask corresponding to the number of bits used by "type"). Signed-off-by:

/proc shows the wrong PID as parent in the following case Process A creates Threads 1 & 2 (using pthread_create) Thread 2 then forks and execs process B getppid() for Process B shows Process A (rightly) as parent, however /proc/B/status shows Thread 3 as PPid (incorrect). Signed-off-by:

I don't know what this is trying to do. It might be some kind of artifact from when get_pgd_slow() was removed. The expanded expression with __pa() ends up looking something like this: (unsigned long)(u64)(u32)pmd-PAGE_OFFSET and that is just nutty because pmd is a pointer now, anyway. Attached patch removes the casts. Signed-off-by:

Below is a patch to suppress printing uninformative errors from ide-floppy.c in response to commands to floppy drives in which no media is present. Without this patch, commands sent to ide-floppy devices without media inserted cause error messages on the console (KERN_ERR level) such as: ide-floppy: ide: I/O error, pc = 0 key = 2, asc = 3a asq = 0 ide-floppy: ide: I/O error, pc = 1b key = 2, asc = 3a asq = 0 ide-floppy: ide: I/O error, pc = 23 key = 2, asc = 3a asq = 0 ide-floppy: ide: I/O error, pc = 1e key = 2, asc = 3a asq = 0 ide-floppy: ide: I/O error, pc = 1e key = 2, asc = 3a asq = 0 Dell's Virtual Floppy (system management presents to the local system an IDE floppy device, which is actually a floppy device in a remote system connected over an IP link) exhibits this also, when connecting to a remote floppy drive with no media present.

Some controller BIOSes have problems with the legacy int13 fn02 READ SECTORS command. int13 fn42 EXTENDED READ is used in preference by most boot loaders today, so lets use that. If EXTENDED READ fails or isn't supported, fall back to READ SECTORS. This hopefully resolves the three reports of BIOSes which would either long-pause (30+ seconds) or hang completely on the legacy READ SECTORS command. This also adds CONFIG_EDD_SKIP_MBR to eliminate reading the MBR on each BIOS-presented disk, in case there are further problems in this area. Signed-off-by:

This patch prevents execution of hvc_write() and hvc_hangup() after the tty layer has executed a final hvc_close() against a device. This patch provides a better method than was previously used. tty->driver_data is no longer invalidated so we'll no longer get oopses when the tty layer allows late hangup() and write() operations. - Removed silly tty->driver_data = NULL; from hvc_close which prevents possible oops in hvc_write() and hvc_hangup() due to improperly acting ldisc close ordering. - Added hp->count <= 0 check to hvc_write() and hvc_hangup() to prevent execution of these function after hvc_close() has been invoked by the tty layer. Same tty ldisc issues as above are the reason. - Added some comments to clarify the situation. - Awaiting a forth coming patch from Alan Cox which should clean up the close ordering and prevent the late hangup and write ops from happening.

The error exit path in request_firmware frees the allocated struct firmware *firmware, which is good. What is not so good is that the value of firmware has already been copied out to the caller as *firmware_p. The risk is that the caller will pass this to release_firmware, a double free. This is exactly what will happen if the caller copied the example code if(request_firmware(&fw_entry, $FIRMWARE, device) == 0) copy_fw_to_device(fw_entry->data, fw_entry->size); release(fw_entry); from the firmware documentation.

Amiga frame buffer: We used to have a local hack in fbmem.c to always call the fbdev setup() routines, even when an fbdev was explicitly disabled on the kernel command line (video=xxx:off). This allowed amifb to suspend the monitor, but program the sync generator of the video controller in Denise/Lisa to a 31 kHz/70 Hz mode, increasing the maximum audio playback frequency. Thanks to the recently introduced fb_get_options() routine, we can kill the local hack and just use the return value of fb_get_options(). Signed-off-by:

Kirill's kernel/pid.c rework broke optimization logic in detach_pid(). Non zero return from __detach_pid() was used to indicate, that this pid can probably be freed. Current version always (modulo idle threads) return non zero value, thus resulting in unneccesary pid_hash scanning. Also, uninlining __detach_pid() reduces pid.o text size from 2492 to 1600 bytes.
