commit 088f294609d8f8816dc316681aef2eb61982e0da upstream.

If iov_iter_zero succeeds after failed copy_from_kernel_nofault,
we need to reset the ret value to zero otherwise it will be returned
as final return value of read_kcore_iter.

This fixes objdump -d dump over /proc/kcore for me.

fs/proc/kcore.c: fix coccinelle reported ERROR instances

[ Upstream commit 82e33f249f1126cf3c5f39a31b850d485ac33bc3 ]

Coccinelle complains about the nested reuse of the pointer `iter' with
different pointer type:

./fs/proc/kcore.c:515:26-30: ERROR: invalid reference to the index variable of the iterator on line 499
./fs/proc/kcore.c:534:23-27: ERROR: invalid reference to the index variable of the iterator on line 499

./fs/proc/kcore.c:614:26-30: ERROR: invalid reference to the index variable of the iterator on line 499

Replacing `struct kcore_list *iter' with `struct kcore_list *tmp' doesn't change the
scope and the functionality is the same and coccinelle seems happy.

NOTE: There was an issue with using `struct kcore_list *pos' as the nested iterator.
The build did not work!

fs/proc/kcore.c: allow translation of physical memory addresses

commit 3d5854d75e3187147613130561b58f0b06166172 upstream.

fs/proc/kcore.c: allow translation of physical memory addresses

commit 3d5854d75e3187147613130561b58f0b06166172 upstream.

When /proc/kcore is read an attempt to read the first two pages results in
HW-specific page swap on s390 and another (so called prefix) pages are
accessed instead. That leads to a wrong read.

Allow architecture-specific translation of memory addresses using
kc_xlate_dev_mem_ptr() and kc_unxlate_dev_mem_ptr() callbacks similarily
to /dev/mem xlate_dev_mem_ptr() and unxlate_dev_mem_ptr() callbacks. That
way an architecture can deal with specific physical memory ranges.

Re-use the existing /dev/mem callback implementation on s390, which
handles the described prefix pages swapping correctly.

For other architectures the default callback is basically NOP. It is
expected the condition (vaddr == __va(__pa(vaddr))) always holds true for
KCORE_RAM memory type.

fs/proc/kcore: reinstate bounce buffer for KCORE_TEXT regions

Some architectures do not populate the entire range categorised by
KCORE_TEXT, so we must ensure that the kernel address we read from is
valid.

Unfortunately there is no solution currently available to do so with a
purely iterator solution so reinstate the bounce buffer in this instance
so we can use copy_from_kernel_nofault() in order to avoid page faults
when regions are unmapped.

This change partly reverts commit 2e1c0170771e ("fs/proc/kcore: avoid
bounce buffer for ktext data"), reinstating the bounce buffer, but adapts
the code to continue to use an iterator.
