XFS needs `laptop_mode'.

The old drivers/char sh-sci driver is no long used by anyone, both sh and

*** Warning: "memcmp" [drivers/atm/zatm.ko] undefined!

gcc 3.4 specific problem.  This patch should fix it.  Actually it would be
better to move all these EXPORT_SYMBOLs into lib/string.c, it is silly that
each arch has to duplicate all that.

From: Christoph Hellwig <hch@lst.de>

Someone blindly added sysfs support to the driver long time ago without
understanding the implications (and if they were understood the driver
would need half a rewrite for it).  Herber Xu recently noticed the problems
this causes on unload, so let's if 0 out all that code and get the driver
working again.

It's silly that writing to /proc/sysrq-trigger does nothing if you haven't
enabled /proc/sys/kernel/sysrq.  So provide a new __handle_sysrq() which
ignores the sysrq_enabled check.

The patch also withdraws __handle_sysrq_nolock() from the kernel API.  It had
no callers.

This patch makes the following code work again:

#ifdef STT_REGISTER
                if (info->hdr->e_machine == EM_SPARC ||
                    info->hdr->e_machine == EM_SPARCV9) {
                        /* Ignore register directives. */
                        if (ELF_ST_TYPE(sym->st_info) == STT_REGISTER)
                                break;
                }
#endif

This portion of code is sparc specific and nothing else in modpost.c uses
e_machine meaning cross-compiling for sparc on i386 (or any little endian
machine) is the only way to experience the bug.

Without it, e_machine has the wrong value and modpost then generates a lot
of "*** Warning: \"symbol\" [filename.ko] undefined" messages.

The patch below resolves the "Not Yet Implemented" print_modules() thing.
This is a really useful feature for distros; it allows us to do statistical
analysis on which modules are present how often in oopses compared to how
often they are used normally.  In addition it helps to spot candidates for
certain bugs without having to go back to the customer asking for this
information.

Thanks to Standford guys, a case where reiserfs can dereference NULL

The block layer checks for -EINVAL from block layer driver ioctls.  This is
wrong - ENOTTY is unknown and some drivers correctly use this.  I suspect
for an internal ioctl 2.7 should change to -ENOIOCTLCMD and bitch about old
style returns

This is conservative fix for the 2.6 case, it keeps the bogus -EINVAL to
avoid breaking stuff

From: Greg Edwards <edwardsg@sgi.com>

On ia64, EXEC_PAGESIZE (max page size) is 65536, but the default page size is
16k.  This results in NGROUPS_PER_BLOCK in include/linux/sched.h being
calculated incorrectly when the page size is anything other than 64k.  For
example, on a 16k page size kernel, a setgroups() call with a gidsetsize of
65536 will end up walking over memory since only 1/4 of the needed pages were
allocated for the blocks[] array in the group_info struct.

Patch below calculates NGROUPS_PER_BLOCK from PAGE_SIZE instead.

The laptop mode control script incorrectly guesses XFS_HZ=1000.  This is
incorrect, since the patches that made XFS use USER_HZ went into 2.6.6 as
well.  This changes XFS_HZ to 100 and removes the warning from the doc about
checking XFS_HZ.

Expose the blockdev's VM readahead in /sys/block/hda/queue/read_ahead_kbytes

This duplicates `blockdev --setra', but we're trying to get away from
ioctls.

It would be nice to have a readahead-setting mechanism which also allows,
say, NFS to be tuned.  But there is no common exposure point for
backing_dev_infos.  One option might be per-superblock:

	mount -o remount,read_ahead_kbytes=64

but the generic remount code also has no visibility of the backing_dev, so it
would need a new super_block operation.  One which doesn't accidentally modify
default_backing_dev_info.

EFI-enabled kernels crash on non-EFI machines.  efivars_init() and
efivars_exit() need to check efi_enabled instead of assuming that the
system is using EFI.

From: Arjan van de Ven <arjanv@redhat.com>

the patch below adds a "make buildcheck" target which checks for the "uses
exit in init" bug using Keith Owen's script.  In the future other similar
sanity checks can be added to this target, but even just this one has been
quite useful already.  I use it in the kernel rpm build process for
example, and I'm sure the OSDL build testers can/want to use it too.

Kallsyms discards symbols with the same address, but these are sometimes
useful.  Skip this minor optimization and make kallsyms_lookup deal with
aliases

From: Rusty Russell <rusty@rustcorp.com.au>

The current code doesn't show the last symbol (usually _einittext) in
/proc/kallsyms.  The reason for this is subtle: s_start() returns an empty
string for position 0 (ignored by s_show()), and s_next() returns the first
symbol for position 1.

What should happen is that update_iter() for position 0 should fill in the
first symbol.  Unfortunately, the get_ksymbol_core() fills in the symbol
information, *and* updates the iterator: we have to split these functions,
which we do by making it return the length of the name offset.

Then we can call get_ksymbol_core() without moving the iterator, meaning
that we can call it at position 0 (ie.  s_start()).

From: Jens Axboe <axboe@suse.de>

Move both request_queue and io_context allocation to a slab cache.

This is mainly a space-saving exercise.  Some setups have a lot of disks
