parisc: Fix missing binfmt_elf32.o build error
The MIPS kernel memset / bzero implementation includes a small_memset
branch which is used when the region to be set is smaller than a long (4
bytes on 32bit, 8 bytes on 64bit). The current small_memset
implementation uses a simple store byte loop to write the destination.
There are 2 issues with this implementation:
1. When EVA mode is active, user and kernel address spaces may overlap.
Currently the use of the sb instruction means kernel mode addressing is
always used and an intended write to userspace may actually overwrite
some critical kernel data.
2. If the write triggers a page fault, for example by calling
__clear_user(NULL, 2), instead of gracefully handling the fault, an OOPS
is triggered.
Fix these issues by replacing the sb instruction with the EX() macro,
which will emit EVA compatible instuctions as required. Additionally
implement a fault fixup for small_memset which sets a2 to the number of
bytes that could not be cleared (as defined by __clear_user).

Both ecryptfs_filldir() and ecryptfs_readlink_lower() use
ecryptfs_decode_and_decrypt_filename() to translate lower filenames to
upper filenames. The function correctly passes up lower filenames,
unchanged, when filename encryption isn't in use. However, it was also
passing up lower filenames when the filename wasn't encrypted or
when decryption failed. Since 88ae4ab980, eCryptfs refuses to lookup
lower plaintext names when filename encryption is enabled so this
resulted in a situation where userspace would see lower plaintext
filenames in calls to getdents(2) but then not be able to lookup those
filenames.
An example of this can be seen when enabling filename encryption on an
eCryptfs mount at the root directory of an Ext4 filesystem:
$ ls -1i /lower
12 ECRYPTFS_FNEK_ENCRYPTED.FWYZD8TcW.5FV-TKTEYOHsheiHX9a-w.NURCCYIMjI8pn5BDB9-h3fXwrE--
11 lost+found
$ ls -1i /upper
ls: cannot access '/upper/lost+found': No such file or directory
? lost+found
12 test
With this change, the lower lost+found dentry is ignored:
$ ls -1i /lower
12 ECRYPTFS_FNEK_ENCRYPTED.FWYZD8TcW.5FV-TKTEYOHsheiHX9a-w.NURCCYIMjI8pn5BDB9-h3fXwrE--
11 lost+found
$ ls -1i /upper
12 test
Additionally, some potentially noisy error/info messages in the related
code paths are turned into debug messages so that the logs can't be
easily filled.

Normal removal patch does this, but nf_tables_newrule() doesn't obey
this rule during error handling.
It calls nft_trans_rule_add() *after* linking rule, and, if that
fails to allocate memory, it unlinks the rule and then kfree() it --
this is unsafe.
Switch order -- first add rule to transaction list, THEN link it
to public list.
Note: nft_trans_rule_add() uses GFP_KERNEL; it will not fail so this
is not a problem in practice (spotted only during code review).

The problem is that with NF_TABLES_INET set, we implicitly try to use
the ipv6 version as well for NFT_REJECT, but when CONFIG_IPV6 is set to
a loadable module, it's impossible to reach that.
The best workaround I found is to express the above as a Kconfig

Due to a firmware bug, the hypervisor can send an interrupt to a
transmit or receive queue just prior to a partition migration, not
allowing the device enough time to handle it and send an EOI. When
the partition migrates, the interrupt is lost but an "EOI-pending"
flag for the interrupt line is still set in firmware. No further
interrupts will be sent until that flag is cleared, effectively
freezing that queue. To workaround this, the driver will disable the
hardware interrupt and send an H_EOI signal prior to re-enabling it.
This will flush the pending EOI and allow the driver to continue
operation.

When we patch an alternate feature section, we have to adjust any
relative branches that branch out of the alternate section.
But currently we have a bug if we have a branch that points to past
the last instruction of the alternate section, eg:
FTR_SECTION_ELSE
1: b 2f
or 6,6,6
2:
ALT_FTR_SECTION_END(...)
nop
This will result in a relative branch at 1 with a target that equals
the end of the alternate section.
That branch does not need adjusting when it's moved to the non-else
location. Currently we do adjust it, resulting in a branch that goes
off into the link-time location of the else section, which is junk.
The fix is to not patch branches that have a target == end of the
alternate section.

Marvell's PPv2 controller has a Packet Header parser, which uses a
fixed-size TCAM array of filter entries.
The mvpp2 driver reserves some ranges among the 256 TCAM entries to
perform MAC and VID filtering. The rest of the TCAM ids are freely usable
for other features, such as IPv4 proto matching.
This commit fixes the MVPP2_PE_LAST_FREE_TID define that sets the end of
the "free range", which included the MAC range. This could therefore allow
some other features to use entries dedicated to MAC filtering,
lowering the number of unicast/multicast addresses that could be allowed
before switching to promiscuous mode.

As the rbd_assert() here shows has no extra information beyond the verbose
BUG(), we can simply use BUG() directly in its place. This is reliably
detected as not returning on any architecture, since it doesn't depend
on the unlikely() comparison that confused gcc.

currently, the rbd_wait_state_locked() will wait forever if we
can't get our state locked. Example:
rbd map --exclusive test1 --> /dev/rbd0
rbd map test1 --> /dev/rbd1
dd if=/dev/zero of=/dev/rbd1 bs=1M count=1 --> IO blocked
To avoid this problem, this patch introduce a timeout design
in rbd_wait_state_locked(). Then rbd_wait_state_locked() will
return error when we reach a timeout.
This patch allow user to set the lock_timeout in rbd mapping.

Removing couple of duplicate includes, found by "make includecheck".
That leaves 1 duplicate include in arch/s390/kernel/entry.S, which is
there for a reason (it includes generated asm/syscall_table.h twice).

ccflags-y has no effect (no code is built in that directory,
arch/s390/boot/compressed/Makefile defines its own KBUILD_CFLAGS).
Removing ccflags-y together with COMPILE_VERSION.

Commit 81796a3c6a ("s390/decompressor: trim uncompressed
image head during the build") introduced a new
file named vmlinux.bin.full in directory
arch/s390/boot/compressed.
Add this file to the list of ignored files so it does
not show up on git status.

The config options for kexec are currently not under any menu directory. Up
until now this was not a problem as standard kexec is always compiled in
and thus does not create a menu entry. This changed when kexec_file_load
was enabled. Its config option requires a menu entry which, when added
beneath standard kexec option, appears on the main directory above "General
Setup". Thus move the whole block further down such that the entry in now
in "Processor type and features".
While at it also update the help text for kexec file.

Add an ELF loader for kexec_file. The main task here is to do proper sanity
checks on the ELF file. Basically all other functionality was already
implemented for the image loader.
