      kbuild: add symbol prefix arg to kallsyms · 6895f97e
      由 James Hogan 提交于 
      Commit 1f2bfbd0 ("kbuild: link of
vmlinux moved to a script") introduced in v3.5-rc1 broke kallsyms on
architectures which have symbol prefixes.

The --symbol-prefix argument used to be added to the KALLSYMS command
line from the architecture Makefile, however this isn't picked up by the
new scripts/link-vmlinux.sh. This resulted in symbols like
kallsyms_addresses being added which weren't correctly overriding the
weak symbols such as _kallsyms_addresses. These could then trigger
BUG_ONs in kallsyms code.

This is fixed by removing the KALLSYMS addition from the architecture
Makefile, and using CONFIG_SYMBOL_PREFIX in the link-vmlinux.sh script
to determine whether to add the --symbol-prefix argument.

      firmware: fix directory creation rule matching with make 3.82 · 6c7080a6
      由 Mark Asselstine 提交于 
      Attempting to run 'firmware_install' with CONFIG_USB_SERIAL_TI=y when
using make 3.82 results in an error

make[2]: *** No rule to make target `/lib/firmware/./', needed by
`/lib/firmware/ti_3410.fw'.  Stop.

It turns out make 3.82 is picky when matching directory names with
trailing slashes as a result, where make 3.81 would handle this
correctly make 3.82 does not find the rule needed to create the
directory.

The './' seen in the error is added by $(dir) for firmware which
resides in the base firmware src directory, such as
ti_3410.fw.ihex. By performing $(dir) after we prepend the
$(INSTALL_FW_PATH) we can ensure we don't end up with a './' in the
middle of the path and the directory will be properly created.

This change works with make 3.81 and should work with previous
versions as well.

      scripts/decodecode: Fixup trapping instruction marker · 2a95e37c
      由 Borislav Petkov 提交于 
      When dumping "Code: " sections from an oops, the trapping instruction
%rip points to can be a string copy

  2b:*  f3 a5                   rep movsl %ds:(%rsi),%es:(%rdi)

and the line contain a bunch of ":".  Current "cut" selects only the and
the second field output looks funnily overlaid this:

  2b:*  f3 a5                   rep movsl %ds     <-- trapping instruction:(%rsi),%es:(%rdi

Fix this by selecting the remaining fields too.

      localmodconfig: Add debug environment variable LOCALMODCONFIG_DEBUG · 4503379c
      由 Steven Rostedt 提交于 
      If the environment variable LOCALMODCONFIG_DEBUG is set, then debug output
will appear in the make localmodconfig. This will simplify debugging what
people get with their output, as I can just tell people to do:

  LOCALMODCONFIG_DEBUG=1 make localmodconfig 2>out.txt

and have them send me the out.txt. I'll be able to see why things are not
working as they think it should be.

      localmodconfig: Check if configs are already set for selects · d4bb58b5
      由 Steven Rostedt 提交于 
      There are some cases that a required module does not have a prompt
and needs to have another module enabled that selects it to be set.
As localmodconfig is conservative and tries to make the minimum config
without breaking the user's kernel, or keeping the user from using
devices that were loaded when the lsmod was done, all modules that
select this module will also be enabled.

If you needed module A, but module A did not have a prompt but needed
module B to be selected, localmodconfig would make sure B was still
enabled. If not only B selected A, but C, D, E, F, and G also
selected A, then all of those would also be included, as well as the
modules they depend on. This ballooned the number of configs that
localmodconfig would keep.

The fix here is to process the depends first, and then record those
configs that did not have a prompt and needed to be selected.
After the depends are done, check what configs are needed to select
the configs in the list, and if a config that selects it is already
set, then we don't need to do anything else.

If no config that selects the config is set, then just pick one and
try again.

This change brought down the number of selected modules from 290
to 67! Both before and after were run against a config that had 3095
modules enabled.

      localmodconfig: Read in orig config file to avoid extra processing · 4f4c51c9
      由 Steven Rostedt 提交于 
      Read in the entire config file. If there's a config that we depend on
that happens to be in the core set (not a module) then we do not need
to process it as a module.

Currently, we follow the entire depend and selects even if they
are enabled as core and not modules. By checking to make sure that we
only look at modules we can drop the count a little.

From one of my tests, localmodconfig went from taking 3095 set modules
down to 356 before this patch, and down to 290 modules after the change.
