There is the code in the read_symbol function in 'scripts/kallsyms.c':

	if (is_ignored_symbol(name, type))
		return NULL;

	/* Ignore most absolute/undefined (?) symbols. */
	if (strcmp(name, "_text") == 0)
		_text = addr;

But the is_ignored_symbol function returns true for name="_text" and
type='A'. So the next condition is not executed and the _text variable
is always zero.

It makes the wrong kallsyms_relative_base symbol as a result of the code
(CONFIG_KALLSYMS_BASE_RELATIVE is defined):

	if (base_relative) {
		output_label("kallsyms_relative_base");
		output_address(relative_base);
		printf("\n");
	}

Because the output_address function uses the _text variable.

So the kallsyms_lookup function and all related functions in the kernel
do not work properly. For example, the stack trace in oops:

This is just a cleanup addition to Jann's fix to properly update the
transaction ID for the slub slowpath in commit fd4d9c7d ("mm: slub:
add missing TID bump..").

The transaction ID is what protects us against any concurrent accesses,
but we should really also make sure to make the 'freelist' comparison
itself always use the same freelist value that we then used as the new
next free pointer.

Jann points out that if we do all of this carefully, we could skip the
transaction ID update for all the paths that only remove entries from
the lists, and only update the TID when adding entries (to avoid the ABA
issue with cmpxchg and list handling re-adding a previously seen value).

But this patch just does the "make sure to cmpxchg the same value we
used" rather than then try to be clever.

When kmem_cache_alloc_bulk() attempts to allocate N objects from a percpu

from the percpu freelist, then call ___slab_alloc() to allocate the next
element and repopulate the percpu freelist. ___slab_alloc() can re-enable
IRQs via allocate_slab(), so the TID must be bumped before ___slab_alloc()
to properly commit the freelist head change.

Fix it by unconditionally bumping c->tid when entering the slowpath.

The num_remote_opens counter keeps track of the number of open files which must be
maintained by the server at any point. This is a per-tree-connect counter, and the value
of this counter gets displayed in the /proc/fs/cifs/Stats output as a following...

Open files: 0 total (local), 1 open on server
                             ^^^^^^^^^^^^^^^^
As a thumb-rule, we want to increment this counter for each open/create that we
successfully execute on the server. Similarly, we should decrement the counter when
we successfully execute a close.

In this case, an increment was being missed in case of smb2_query_dir_first,
in case of successful open. As a result, we would underflow the counter and we
could even see the counter go to negative after sufficient smb2_query_dir_first calls.

I tested the stats counter for a bunch of filesystem operations with the fix.
And it looks like the counter looks correct to me.

I also check if we missed the increments and decrements elsewhere. It does not
seem so. Few other cases where an open is done and we don't increment the counter are
the compound calls where the corresponding close is also sent in the request.

mmc: sdhci-acpi: Switch signal voltage back to 3.3V on suspend on external microSD on Lenovo Miix 320

Based on a sample of 7 DSDTs from Cherry Trail devices using an AXP288
PMIC depending on the design one of 2 possible LDOs on the PMIC is used
for the MMC signalling voltage, either DLDO3 or GPIO1LDO (GPIO1 pin in
low noise LDO mode).

The Lenovo Miix 320-10ICR uses GPIO1LDO in the SHC1 ACPI device's DSM
methods to set 3.3 or 1.8 signalling voltage and this appears to work
as advertised, so presumably the device is actually using GPIO1LDO for
the external microSD signalling voltage.

But this device has a bug in the _PS0 method of the SHC1 ACPI device,
the DSM remembers the last set signalling voltage and the _PS0 restores
this after a (runtime) suspend-resume cycle, but it "restores" the voltage
on DLDO3 instead of setting it on GPIO1LDO as the DSM method does. DLDO3
is used for the LCD and setting it to 1.8V causes the LCD to go black.

This commit works around this issue by calling the Intel DSM to reset the
signal voltage to 3.3V after the host has been runtime suspended.
This will make the _PS0 method reprogram the DLDO3 voltage to 3.3V, which
leaves it at its original setting fixing the LCD going black.

This commit adds and uses a DMI quirk mechanism to only trigger this
workaround on the Lenovo Miix 320 while leaving the behavior of the
driver unchanged on other devices.

Even though INITRAMFS_SOURCE kconfig option isn't set in most of
defconfigs it is used (set) extensively by various build systems.
Commit f26661e1 ("initramfs: make initramfs compression choice
non-optional") has changed default compression mode. Previously we
compress initramfs using available compression algorithm. Now
we don't use any compression at all by default.
It significantly increases the image size in case of build system
chooses embedded initramfs. Initially I faced with this issue while
using buildroot.

As of today it's not possible to set preferred compression mode
in target defconfig as this option depends on INITRAMFS_SOURCE
being set. Modification of all build systems either doesn't look
like good option.

Let's instead rewrite initramfs compression mode choices list
the way that "INITRAMFS_COMPRESSION_NONE" will be the last option
in the list. In that case it will be chosen only if all other
options (which implements any compression) are not available.

In order to preserve backwards compatability with kmod tools, we have to
move the namespace field in Module.symvers last, as the depmod -e -E
option looks at the first three fields in Module.symvers to check symbol
versions (and it's expected they stay in the original order of crc,
symbol, module).

In addition, update an ancient comment above read_dump() in modpost that
suggested that the export type field in Module.symvers was optional. I
suspect that there were historical reasons behind that comment that are
no longer accurate. We have been unconditionally printing the export
type since 2.6.18 (commit bd5cbced), which is over a decade ago now.

Fix up read_dump() to treat each field as non-optional. I suspect the
original read_dump() code treated the export field as optional in order
to support pre <= 2.6.18 Module.symvers (which did not have the export
type field). Note that although symbol namespaces are optional, the
field will not be omitted from Module.symvers if a symbol does not have
a namespace. In this case, the field will simply be empty and the next
delimiter or end of line will follow.
