[PATCH] i386: Convert some functions to __init to avoid MODPOST warnings

2007-01-11T00:52:44+00:00

o Some functions which should have been in init sections as they are called
  only once. Put them in init sections. Otherwise MODPOST generates warning
  as these functions are placed in .text and they end up accessing something
  in init sections.

WARNING: vmlinux - Section mismatch: reference to .init.text:migration_init
from .text between 'do_pre_smp_initcalls' (at offset 0xc01000d1) and
'run_init_process'

Revert previous attempts at messing with the linux banner string and
simply use a separate format string for proc.

[PATCH] start_kernel: test if irq's got enabled early, barf, and disable them again

2007-01-06T07:55:21+00:00

The calls made by parse_parms to other initialization code might enable
interrupts again way too early.

Having interrupts on this early can make systems PANIC when they initialize
the IRQ controllers (which happens later in the code).  This patch detects
that irq's are enabled again, barfs about it and disables them again as a
safety net.

Driver core: proper prototype for drivers/base/init.c:driver_init()

2006-12-20T18:56:45+00:00

Add a prototype for driver_init() in include/linux/device.h.

Also remove a static function of the same name in drivers/acpi/ibm_acpi.c to
ibm_acpi_driver_init() to fix the namespace collision.

Make sure we populate the initroot filesystem late enough

2006-12-11T20:12:04+00:00

We should not initialize rootfs before all the core initializers have
run.  So do it as a separate stage just before starting the regular
driver initializers.

Make SLES9 "get_kernel_version" work on the kernel binary again

2006-12-11T19:34:11+00:00

As reported by Andy Whitcroft, at least the SLES9 initrd build process
depends on getting the kernel version from the kernel binary.  It does
that by simply trawling the binary and looking for the signature of the
"linux_banner" string (the string "Linux version " to be exact. Which
is really broken in itself, but whatever..)

That got broken when the string was changed to allow /proc/version to
change the UTS release information dynamically, and "get_kernel_version"
thus returned "%s" (see commit a2ee8649ba6d71416712e798276bf7c40b64e6e5:
"[PATCH] Fix linux banner utsname information").

This just restores "linux_banner" as a static string, which should fix
the version finding.  And /proc/version simply uses a different string.

To avoid wasting even that miniscule amount of memory, the early boot
string should really be marked __initdata, but that just causes the same
bug in SLES9 to re-appear, since it will then find other occurrences of
"Linux version " first.

[PATCH] add child reaper to pid_namespace

2006-12-08T16:28:52+00:00

Add a per pid_namespace child-reaper.  This is needed so processes are reaped
within the same pid space and do not spill over to the parent pid space.  Its
also needed so containers preserve existing semantic that pid == 1 would reap
orphaned children.

This is based on Eric Biederman's patch: http://lkml.org/lkml/2006/2/6/285

[PATCH] Fix linux banner utsname information

2006-12-08T16:28:37+00:00

utsname information is shown in the linux banner, which also is used for
/proc/version (which can have different utsname values inside a uts
namespaces).  this patch makes the varying data arguments and changes the
string to a format string, using those arguments.

[PATCH] gcc-4.1.0 is bust

2006-12-07T16:39:44+00:00

Keith says

Compiling 2.6.19-rc6 with gcc version 4.1.0 (SUSE Linux), wait_hpet_tick is
optimized away to a never ending loop and the kernel hangs on boot in timer
setup.

0000001a :
  1a:   55                      push   %ebp
  1b:   89 e5                   mov    %esp,%ebp
  1d:   eb fe                   jmp    1d 

This is not a problem with gcc 3.3.5.  Adding barrier() calls to
wait_hpet_tick does not help, making the variables volatile does.

And the consensus is that gcc-4.1.0 is busted.  Suse went and shipped
gcc-4.1.0 so we cannot ban it.  Add a warning.
