Select this option, if you want to share the text segment of the
Linux kernel between different VM guests. This reduces memory
usage with lots of guests but greatly increases kernel size.
+ Also if a kernel was IPL'ed from a shared segment the kexec system

You should only select this option if you know what you are
doing and want to exploit this feature.

- help
- The initial RAM filesystem is a ramfs which is loaded by the
- boot loader (loadlin or lilo) and that is mounted as root
- before the normal boot procedure. It is typically used to
- load modules needed to mount the "real" root file system,
- etc. See <file:Documentation/initrd.txt> for details.
-
- If RAM disk support (BLK_DEV_RAM) is also included, this

+------------
+Fix mtime bouncing around from local idea of last write times to remote time.
+Fix hang (in i_size_read) when simultaneous size update of same remote file
+on smp system corrupts sequence number. Do not reread unnecessarily partial page
+(which we are about to overwrite anyway) when writing out file opened rw.

Version 1.47

Fix oops in list_del during mount caused by unaligned string.

- Enable the possibility of suspending the machine.
- It doesn't need ACPI or APM.
- You may suspend your machine by 'swsusp' or 'shutdown -z <time>'
- (patch for sysvinit needed).
+ Enable the suspend to disk (STD) functionality.
- It creates an image which is saved in your active swap. Upon next
+ You can suspend your machine with 'echo disk > /sys/power/state'.
+ Alternatively, you can use the additional userland tools available
+ from <http://suspend.sf.net>.
+
+ In principle it does not require ACPI or APM, although for example
+ ACPI will be used if available.
+
+ It creates an image which is saved in your active swap. Upon the next
boot, pass the 'resume=/dev/swappartition' argument to the kernel to
have it detect the saved image, restore memory state from it, and
continue to run as before. If you do not want the previous state to
- be reloaded, then use the 'noresume' kernel argument. However, note
- that your partitions will be fsck'd and you must re-mkswap your swap
- partitions. It does not work with swap files.
+ be reloaded, then use the 'noresume' kernel command line argument.
+ Note, however, that fsck will be run on your filesystems and you will
+ need to run mkswap against the swap partition used for the suspend.
- Right now you may boot without resuming and then later resume but
- in meantime you cannot use those swap partitions/files which were
- involved in suspending. Also in this case there is a risk that buffers
- on disk won't match with saved ones.
+ It also works with swap files to a limited extent (for details see
+ <file:Documentation/power/swsusp-and-swap-files.txt>).
- For more information take a look at <file:Documentation/power/swsusp.txt>.
+ Right now you may boot without resuming and resume later but in the
+ meantime you cannot use the swap partition(s)/file(s) involved in
+ suspending. Also in this case you must not use the filesystems
+ that were mounted before the suspend. In particular, you MUST NOT
+ MOUNT any journaled filesystems mounted before the suspend or they
+ will get corrupted in a nasty way.
- (For now, swsusp is incompatible with PAE aka HIGHMEM_64G on i386.
- we need identity mapping for resume to work, and that is trivial
- to get with 4MB pages, but less than trivial on PAE).
+ For more information take a look at <file:Documentation/power/swsusp.txt>.
