If grub2 loads efifb/vesafb, then when systemd starts it can set the console
font on that framebuffer device, however when we then load the native KMS
driver, the first thing it does is tear down the generic framebuffer driver.
The thing is the generic code is doing the right thing, it frees the font
because otherwise it would leak memory. However we can assume that if you
are removing the generic firmware driver (vesa/efi/offb), that a new driver
*should* be loading soon after, so we effectively leak the font.
However the old code left a dangling pointer in vc->vc_font.data and we
can now reuse that dangling pointer to load the font into the new
driver, now that we aren't freeing it.

When we switch from 256->512 byte font rendering mode, it means the
current contents of the screen is being reinterpreted. The bit that holds
the high bit of the 9-bit font, may have been previously set, and thus
the new font misrenders.
The problem case we see is grub2 writes spaces with the bit set, so it
ends up with data like 0x820, which gets reinterpreted into 0x120 char
which the font translates into G with a circumflex. This flashes up on
screen at boot and is quite ugly.
A current side effect of this patch though is that any rendering on the
screen changes color to a slightly darker color, but at least the screen
no longer corrupts.
v2: as suggested by hpa, always clear the attribute space, whether we
are are going to or from 512 chars.

The seccomp filters are currently built for the build host, not for the
machine that they are going to run on, but they are also built for with
the -m32 flag if the kernel is built for a 32 bit machine, both of which
seems rather odd.
It broke allyesconfig on my machine, which is x86-64, but building for
32 bit ARM, with this error message:
In file included from /usr/include/stdio.h:28:0,
from samples/seccomp/bpf-fancy.c:15:
/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directory
because there are no 32 bit libc headers installed on this machine. We
should really be building all the samples for the target machine rather
than the build host, but since the infrastructure for that appears to be
missing right now, let's be a little bit smarter and not pass the '-m32'
flag to the HOSTCC when cross- compiling.

The macro for_each_memcg_cache_index contains a silly yet potentially
deadly mistake. Although the macro parameter is _idx, the loop tests
are done over i, not _idx.
This hasn't generated any problems so far, because all users use i as a
loop index. However, while playing with an extension of the code I
ended using another loop index and the compiler was quick to complain.
Unfortunately, this is not the kind of thing that testing reveals =(

There exists a situation when GC can work in background alone without
any other filesystem activity during significant time.
The nilfs_clean_segments() method calls nilfs_segctor_construct() that
updates superblocks in the case of NILFS_SC_SUPER_ROOT and
THE_NILFS_DISCONTINUED flags are set. But when GC is working alone the
nilfs_clean_segments() is called with unset THE_NILFS_DISCONTINUED flag.
As a result, the update of superblocks doesn't occurred all this time
and in the case of SPOR superblocks keep very old values of last super
root placement.
SYMPTOMS:
Trying to mount a NILFS2 volume after SPOR in such environment ends with
very long mounting time (it can achieve about several hours in some
cases).
REPRODUCING PATH:
1. It needs to use external USB HDD, disable automount and doesn't
make any additional filesystem activity on the NILFS2 volume.
2. Generate temporary file with size about 100 - 500 GB (for example,
dd if=/dev/zero of=<file_name> bs=1073741824 count=200). The size of
file defines duration of GC working.
3. Then it needs to delete file.
4. Start GC manually by means of command "nilfs-clean -p 0". When you
start GC by means of such way then, at the end, superblocks is updated
by once. So, for simulation of SPOR, it needs to wait sometime (15 -
40 minutes) and simply switch off USB HDD manually.
5. Switch on USB HDD again and try to mount NILFS2 volume. As a
result, NILFS2 volume will mount during very long time.
REPRODUCIBILITY: 100%
FIX:
This patch adds checking that superblocks need to update and set
THE_NILFS_DISCONTINUED flag before nilfs_clean_segments() call.

When we have group with mixed events (hw/sw) we want to end up
with group leader being in hw context. So if group leader is
initialy sw event, we move all the events under hw context.
The move is done for each event by removing it from its context
and adding it back into proper one. As a part of the removal the
event is automatically disabled, which is not what we want at
this stage of creating groups.
The fix is to initialize event state after removal from sw
context.
This fix resulted from the following discussion:

"A few more radeon fixes for 3.8. Mostly small stuff. The big
change is disabling the use of the DMA ring for VM PT updates. This
reverts back to the 3.7 behavior. Problem is we can get huge PT
updates in certain cases that are too big for the DMA ring. I've
got patches to use an IB for this so I can re-enable the use of the
DMA ring for VM PT updates in 3.9. This request also includes the
patches from the last pull request I sent on Monday in case you haven't
pulled them yet."

This patch fixes a possible divide by zero bug when the fabric_max_sectors
device attribute is written and backend se_device failed to be successfully
configured -> enabled.
Go ahead and use block_size=512 within se_dev_set_fabric_max_sectors()
in the event of a target_configure_device() failure case, as no valid
dev->dev_attrib.block_size value will have been setup yet.

This patch fixes a v3.8-rc1 regression bug where an unconfigured se_device
was incorrectly allowed to perform a fabric port-link. This bug was
introduced in commit:
commit 0fd97ccf45
Author: Christoph Hellwig <hch@infradead.org>
Date: Mon Oct 8 00:03:19 2012 -0400
target: kill struct se_subsystem_dev
which ended up dropping the original se_subsystem_dev->se_dev_ptr check
preventing this from happening with pre commit 0fd97ccf code.

For large VM page table updates, we can sometimes generate
more packets than there is space on the ring. This happens
more readily with the DMA ring since it is 64K (vs 1M for the
CP). For now, switch back to the CP. For the next kernel,
I have a patch to utilize IBs for VM PT updates which
alleviates this problem.

If the requested number of DWs on the ring is larger than
the size of the ring itself, return an error.
In testing with large VM updates, we've seen crashes when we
try and allocate more space on the ring than the total size
of the ring without checking.
This prevents the crash but for large VM updates or bo moves
of very large buffers, we will need to break the transaction
down into multiple batches. I have patches to use IBs for
the next kernel.
