All modules that need CONFIG_CRC_CCITT already select it, so there is no
need to bother users about the option.

<title>arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FS</title>

<content type='text'>
Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.

Get rid of it mechanically:

   git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
       xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'

Also just remove the AUTOFS4_FS config option stub.  Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.

<title>powerpc/64s: Default to 64K pages for 64 bit book3s</title>

For 64-bit book3s the default should be 64K as that's what modern CPUs
are designed for.

The following defconfigs already set CONFIG_PPC_64K_PAGES:

 cell_defconfig
 pasemi_defconfig
 powernv_defconfig
 ppc64_defconfig
 pseries_defconfig
 skiroot_defconfig

The have the option removed from the defconfig, as it is now the
default.

The defconfigs that now need to set CONFIG_PPC_4K_PAGES to maintain
their existing behaviour are:

 g5_defconfig
 maple_defconfig
 microwatt_defconfig
 ps3_defconfig

<title>arch: powerpc: Stop building and using oprofile</title>

The "oprofile" user-space tools don't use the kernel OPROFILE support
any more, and haven't in a long time. User-space has been converted to
the perf interfaces.

This commits stops building oprofile for powerpc and removes any
reference to it from directories in arch/powerpc/ apart from
arch/powerpc/oprofile, which will be removed in the next commit (this is
broken into two commits as the size of the commit became very big, ~5k
lines).

Note that the member "oprofile_cpu_type" in "struct cpu_spec" isn't
removed as it was also used by other parts of the code.

<title>vgacon: remove software scrollback support</title>

<id>urn:sha1:973c096f6a85e5b5f2a295126ba6928d9a6afd45</id>
<content type='text'>
Yunhai Zhang recently fixed a VGA software scrollback bug in commit
ebfdfeeae8c0 ("vgacon: Fix for missing check in scrollback handling"),
but that then made people look more closely at some of this code, and
there were more problems on the vgacon side, but also the fbcon software
scrollback.

We don't really have anybody who maintains this code - probably because
nobody actually _uses_ it any more.  Sure, people still use both VGA and
the framebuffer consoles, but they are no longer the main user
interfaces to the kernel, and haven't been for decades, so these kinds
of extra features end up bitrotting and not really being used.

So rather than try to maintain a likely unused set of code, I'll just
aggressively remove it, and see if anybody even notices.  Maybe there
are people who haven't jumped on the whole GUI badnwagon yet, and think
it's just a fad.  And maybe those people use the scrollback code.

If that turns out to be the case, we can resurrect this again, once
we've found the sucker^Wmaintainer for it who actually uses it.

<content type='text'>
This kernel configuration is basically enabling/disabling sr driver quirks
detection. While these quirks are for fairly rare devices (very old CD
burners, and a glucometer), the additional detection of these models is a
very minimal amount of code.

The logic behind the quirks is always built into the sr driver.

This also removes the config from all the defconfig files that are enabling
this already.

Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable
   CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
   made default to 'n',
2. It is not recommended (help message: "This should not be used today
   [...] creates a high system load") and was kept only for ancient
   userland,
3. Certain userland specifically requests it to be disabled (systemd
   README: "Legacy hotplug slows down the system and confuses udev").

MTD_NAND is large and encloses much more than what the symbol is

MTD_RAW_NAND instead.
