Bank0/Bank1 are not in ECC mode, so no need to check.
Each bank contains 8 words, so we check (phy_index > 15).Signed-off-by: Peng Fan

Add ULP1 OTP support.
No timing required for ULP1 OTP.
The CTRL_ADDR is 8 bits width.
When finished access to OTP, gate the power to OTP memory to save power.Fix store, when invalid args, not return 0, but return the error values.
To ULP, fuse only support being programmed once, so add a check before
program.Test log:

Support i.MX6SLL OTP.
There are 4 works in bank7/bank8.
When read, use address offset.
When prog, use bank/index, note that bank7/bank8 we treat
them a single bank when prog.Tested GP41 and GP31 read/write on eng sample chip.

ENGR00292341 imx6sl hwrng
Add hwrng support for i.MX6SL.
1. Add RNG driver. This driver originated as fsl-rngc.c. It
has been modified to support device tree. The name has been
changed since it supports both b and c variants of RNG.
2. Added clock and compatible info to the device tree data.
3. Added the entry in the options in the Kconfig for hwrng.(cherry picked from commit 1f3f2c0647b7319c4e23293a61512e4191593513)

This is porting of fsl_otp driver from imx_3.14.y to imx_4.1.y.
This patch mainly from the following:
commit:292eff6d2c9064ecf15ed457140c1d743c2ead67
"ENGR00269945: char: add fsl_otp deivce driver"
This is a porting of fsl_otp driver from 3.0.35 kernel to 3.10. It
cleans up the driver a little bit and adds device tree probe support.shawn.guo: cherry-pick commit 850237dccde7 from imx_3.10.y.

"MLK-10979-4 imx: ocotp add i.MX7D support and fix hole"
1. Add i.MX7D support
2. Fix hole addressing.
There is a hole in shadow registers address map of size 0x100
between bank 5 and bank 6 on iMX6QP, iMX6DQ, iMX6SDL, iMX6SX and
iMX6UL. Bank 5 ends at 0x6F0 and Bank 6 starts at 0x800. When reading
the fuses, should account for this hole in address space.Similar hole exists between bank 14 and bank 15 of size 0x80 on
iMX6QP, iMX6DQ, iMX6SDL and iMX6SX.
Note: iMX6SL has only 0-7 banks and there is no hole.
Note: iMX6UL doesn't have this one.When reading, the hole need to be considered to calculated the physical
address offset.
When writing, since only word index for i.MX6 and bank
index for i.MX7, there is no need to take the hole into consideration,
still use the bank/word index from fuse map.
3. Add i.MX6SL i.MX6UL fuse map table.
4. Tested read/write on mx6ul-14x14-ddr3-arm2 and mx7d-12x12-lpddr3-arm2 board.
Tested read on mx6sxsabresd board.Signed-off-by: Shawn Guo

commit 488debb9971bc7d0edd6d8080ba78ca02a04f6c4 upstream.
When borrowing the pfn_valid() check from mmap_kmem(), somebody managed
to get physical and virtual addresses spectacularly muddled up, such
that we've ended up with checks for one being the other. Whilst this
does indeed prevent out-of-bounds accesses crashing, on most systems
it also prevents the more desirable use-case of working at all ever.Check the *virtual* offset correctly for what it is. Furthermore, do
so in the right place - a read or write may span multiple pages, so a
single up-front check is insufficient. High memory accesses already
have a similar validity check just before the copy_to_user() call, so
just make the low memory path fully consistent with that.Reported-by: Jason A. Donenfeld

commit 26a137e31ffe6fbfdb008554a8d9b3d55bd5c86e upstream.
If the TPM we're connecting to uses a static burst count, it will report
a burst count of zero throughout the response read. However, get_burstcount
assumes that a response of zero indicates that the TPM is not ready to
receive more data. In this case, it returns a negative error code, which
is passed on to tpm_tis_{write,read}_bytes as a u16, causing
them to read/write far too many bytes.This patch checks for negative return codes and bails out from recv_data
and tpm_tis_send_data.Fixes: 1107d065fdf1 (tpm_tis: Introduce intermediate layer for TPM access)

The Aspeed SoCs have two BT interfaces : one is IPMI compliant and the
other is H8S/2168 compliant.The current ipmi/bt-bmc driver implements the IPMI version and we
should reflect its nature in the compatible node name using
'aspeed,ast2400-ibt-bmc' instead of 'aspeed,ast2400-bt-bmc'. The
latter should be used for a H8S interface driver if it is implemented
one day.Signed-off-by: Cédric Le Goater

Commit c6017e793b93 ("virtio: console: add locks around buffer removal
in port unplug path") added locking around the freeing of buffers in the
vq. However, when free_buf() is called with can_sleep = true and rproc
is enabled, it calls dma_free_coherent() directly, requiring interrupts
to be enabled. Currently a WARNING is triggered due to the spin locking
around free_buf, with a call stack like this:WARNING: CPU: 3 PID: 121 at ./include/linux/dma-mapping.h:433

The __latent_entropy gcc attribute can be used only on functions and

gathering control-flow entropy. If the attribute is on a variable then
the plugin will initialize it with random contents. The variable must
be an integer, an integer array type or a structure with integer fields.These specific functions have been selected because they are init
functions (to help gather boot-time entropy), are called at unpredictable
times, or they have variable loops, each of which provide some level of
latent entropy.Signed-off-by: Emese Revfy

Pull VFS splice updates from Al Viro:
"There's a bunch of branches this cycle, both mine and from other folks
and I'd rather send pull requests separately.This one is the conversion of ->splice_read() to ITER_PIPE iov_iter
(and introduction of such). Gets rid of a lot of code in fs/splice.c
and elsewhere; there will be followups, but these are for the next
cycle... Some pipe/splice-related cleanups from Miklos in the same
branch as well"* 'work.splice_read' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
pipe: fix comment in pipe_buf_operations
pipe: add pipe_buf_steal() helper
pipe: add pipe_buf_confirm() helper
pipe: add pipe_buf_release() helper
pipe: add pipe_buf_get() helper
relay: simplify relay_file_read()
switch default_file_splice_read() to use of pipe-backed iov_iter
switch generic_file_splice_read() to use of ->read_iter()
new iov_iter flavour: pipe-backed
fuse_dev_splice_read(): switch to add_to_pipe()
skb_splice_bits(): get rid of callback
new helper: add_to_pipe()
splice: lift pipe_lock out of splice_to_pipe()
splice: switch get_iovec_page_array() to iov_iter
splice_to_pipe(): don't open-code wakeup_pipe_readers()
