clang build fails with
fs/udf/partition.c:86:28: error: variable 'loc' is uninitialized when used here [-Werror,-Wuninitialized]
sb, block, partition, loc, index);
^~~
loc is now only known when bh is valid. So remove reporting loc in debug
output.

Fix problems noted in compilion with -Wformat=2 -Wformat-signedness.
In particular, a mismatch between the signedness of a value and the
signedness of its format specifier can result in unsigned values being
printed as negative numbers, e.g.:
Partition (0 type 1511) starts at physical 460, block length -1779968542
...which occurs when mounting a large (> 1 TiB) UDF partition.
Changes since V1:
* Fixed additional issues noted in udf_bitmap_free_blocks(),
udf_get_fileident(), udf_show_options()

UDF/OSTA terminology is confusing. Partition Numbers (PNs) are arbitrary
16-bit values, one for each physical partition in the volume. Partition
Reference Numbers (PRNs) are indices into the the Partition Map Table
and do not necessarily equal the PN of the mapped partition.
The current metadata code mistakenly uses the PN instead of the PRN when
mapping metadata blocks to physical/sparable blocks. Windows-created
UDF 2.5 discs for some reason use large, arbitrary PNs, resulting in
mount failure and KASAN read warnings in udf_read_inode().
For example, a NetBSD UDF 2.5 partition might look like this:
PRN PN Type
--- -- ----
0 0 Sparable
1 0 Metadata
Since PRN == PN, we are fine.
But Windows could gives us:
PRN PN Type
--- ---- ----
0 8192 Sparable
1 8192 Metadata
So udf_read_inode() will start out by checking the partition length in
sbi->s_partmaps[8192], which is obviously out of bounds.
Fix this by creating a new field (s_phys_partition_ref) in struct
udf_meta_data, referencing whatever physical or sparable map has the
same partition number as the metadata partition.
[JK: Add comment about s_phys_partition_ref, change its name]

Currently when udf_get_pblock_meta25() fails to map a block using the
primary metadata file, it will attempt to load the mirror file entry by
calling udf_find_metadata_inode_efe(). That function will return a ERR_PTR
if it fails, but the return value is only checked against NULL. Test the
return value using IS_ERR() and change it to NULL if needed.

Currently, if a metadata partition map is missing its partition descriptor,
then udf_get_pblock_meta25() will BUG() out the first time it is called.
This is rather drastic for a corrupted filesystem, so just treat this case
as an invalid mapping instead.

uses of pr_warn.
Rename function udf_warning to _udf_warn.
Remove __func__ from uses and move __func__ to a new udf_warn

Add \n's to uses of udf_warn, remove \n from _udf_warn.

implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

There's really no reason to keep udf headers in include/linux as they're
not used by anything but fs/udf/.
This patch merges most of include/linux/udf_fs_i.h into fs/udf/udf_i.h,
include/linux/udf_fs_sb.h into fs/udf/udf_sb.h and
include/linux/udf_fs.h into fs/udf/udfdecl.h.
The only thing remaining in include/linux/ is a stub of udf_fs_i.h
defining the four user-visible udf ioctls. It's also moved from
unifdef-y to headers-y because it can be included unconditionally now.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
