linux-toradex.git/kernel/module/kallsyms.c, branch v5.19-rc1 Linux kernel for Apalis and Colibri modules module: Introduce data_layout 2022-04-05T15:43:05+00:00 Christophe Leroy christophe.leroy@csgroup.eu 2022-02-23T12:02:13+00:00 6ab9942c44b2d213a16b2620e4baf0223122222f In order to allow separation of data from text, add another layout, called data_layout. For architectures requesting separation of text and data, only text will go in core_layout and data will go in data_layout. For architectures which keep text and data together, make data_layout an alias of core_layout, that way data_layout can be used for all data manipulations, regardless of whether data is in core_layout or data_layout.

In order to allow separation of data from text, add another layout,
called data_layout. For architectures requesting separation of text
and data, only text will go in core_layout and data will go in
data_layout.

For architectures which keep text and data together, make data_layout
an alias of core_layout, that way data_layout can be used for all
data manipulations, regardless of whether data is in core_layout or
data_layout.

module: Rename debug_align() as strict_align() 2022-04-05T15:43:04+00:00 Christophe Leroy christophe.leroy@csgroup.eu 2022-02-23T09:01:01+00:00 7337f929d5672e37a80c8582d357f084320f475f debug_align() was added by commit 84e1c6bb38eb ("x86: Add RO/NX protection for loadable kernel modules") At that time the config item was CONFIG_DEBUG_SET_MODULE_RONX. But nowadays it has changed to CONFIG_STRICT_MODULE_RWX and debug_align() is confusing because it has nothing to do with DEBUG. Rename it strict_align() Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> 
debug_align() was added by commit 84e1c6bb38eb ("x86: Add RO/NX
protection for loadable kernel modules")

At that time the config item was CONFIG_DEBUG_SET_MODULE_RONX.

But nowadays it has changed to CONFIG_STRICT_MODULE_RWX and
debug_align() is confusing because it has nothing to do with
DEBUG.

Rename it strict_align()
