kernel/init, branch linux-2.6.16.y

gcc-4.1.0 is bust

2007-05-22T21:50:21Z

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.

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

2007-04-20T22:10:28Z

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.

[PATCH] kexec: fix in free initrd when overlapped with crashkernel region

2006-02-10T16:13:12Z

It is possible that the reserved crashkernel region can be overlapped with initrd since the bootloader sets the initrd location. When the initrd region is freed, the second kernel memory will not be contiguous. The Kexec_load can cause an oops since there is no contiguous memory to write the second kernel or this memory could be used in the first kernel itself and may not be part of the dump. For example, on powerpc, the initrd is located at 36MB and the crashkernel starts at 32MB. The kexec_load caused panic since writing into non-allocated memory (after 36MB). We could see the similar issue even on other archs. One possibility is to move the initrd outside of crashkernel region. But, the initrd region will be freed anyway before the system is up. This patch fixes this issue and frees only regions that are not part of crashkernel memory in case overlaps. Signed-off-by: Haren Myneni Acked-by: "Eric W.

[PATCH] selinux: require AUDIT

2006-02-08T00:12:33Z

Make SELinux depend on AUDIT as it requires the basic audit support to log permission denials at all. Note that AUDITSYSCALL remains optional for SELinux, although it can be useful in providing further information upon denials.

[PATCH] don't allow users to set CONFIG_BROKEN=y

2006-02-03T16:32:03Z

Do not allow people to create configurations with CONFIG_BROKEN=y. The sole reason for CONFIG_BROKEN=y would be if you are working on fixing a broken driver, but in this case editing the Kconfig file is trivial. Never ever should a user enable CONFIG_BROKEN.
