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. Signed-off-by:

This fixes 2 memory leaks in swsusp: during relocating pagedir, eaten pages were not properly freed in error path and even regular freeing path was freeing one page too little. Signed-off-by:

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 way it works for queued block sg requests as well. Signed-Off-By:

Mt rainier probe must be deferred to media load time, since it requires a valid media (the drive may present a different capability based on what media is loaded). This fixes that for ide-cd and sr. Signed-Off-By:

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.

Avoid taking down_write(mmap_sem) unless we really need it. Seems that the only reason we're taking it for writing is to protect vma->vm_flags. Signed-off-by:

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. Original patch by: Arnd Bergmann <arnd@arndb.de> Signed-off-by:

- "\<" 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, ...

This file provides ability for caller of register_cpu() to either create a control file, or not. This can be handy if a particular platform decides that certain CPU's are not removable. Hence would like to not create a control file. Signed-off-by:

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. Signed-off-by:

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(). Signed-off-by:

William Lee Irwin III authored
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:

William Lee Irwin III authored
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. Signed-off-by:
