mem= command line option was being ignored in arch/powerpc if we were not a CONFIG_MULTIPLATFORM (which is handled via prom_init stub). The initial command line extraction and parsing needed to be moved earlier in the boot process and have code to actual parse mem= and do something about it. Also, fixed a compile warning in the file.

When compiling a non-default subarch, topology.c is missing from the kernel build. This causes builds with CONFIG_HOTPLUG_CPU to fail. In addition, on Intel processors with cpuid level > 4, it causes intel_cacheinfo.c to reference uninitialized data that should have been set up by the initcall in topology.c which calls register_cpu. This causes a kernel panic on boot on newer Intel processors. Moving topology.c to arch/i386/kernel fixes both of these problems. Thanks to Dan Hecht for finding and fixing this problem.

- PF_SWAPWRITE needs to be set for RECLAIM_SWAP to be able to write out pages to swap. Currently RECLAIM_SWAP may not do that. - remove setting nr_reclaimed pages after slab reclaim since the slab shrinking code does not use that and the nr_reclaimed pages is just right for the intended follow up action.

I'm currently at the POSIX meeting and one thing covered was the incompatibility of Linux's link() with the POSIX definition. The name. Linux does not follow symlinks, POSIX requires it does. Even if somebody thinks this is a good default behavior we cannot change this because it would break the ABI. But the fact remains that some application might want this behavior. We have one chance to help implementing this without breaking the behavior. For this we could use the new linkat interface which would need a new flags parameter. If the new parameter is AT_SYMLINK_FOLLOW the new behavior could be invoked. I do not want to introduce such a patch now. But we could add the parameter now, just don't use it. The patch below would do this. Can we get this late patch applied before the release more or less fixes the syscall API? Signed-off-by:

Recent GDT changes broke the SMP boot sequence if the booting CPU is numbered anything other than zero. There's also a subtle source of error in that the boot time CPU now uses cpu_gdt_table (which is actually the GDT for booting CPUs in head.S). This patch fixes both problems by making GDT descriptors themselves allocated from a per_cpu area and switching to them in cpu_init(), which now means that cpu_gdt_table is exclusively used for booting CPUs again.

migrate_pages_to() allocates a list of new pages on the intended target node or with the intended policy and then uses the list of new pages as targets for the migration of a list of pages out of place. When the pages are allocated it is not clear which of the out of place pages will be moved to the new pages. So we cannot specify an address as needed by alloc_page_vma(). This causes problem for MPOL_INTERLEAVE which will currently allocate the pages on the first node of the set. If mbind is used with vma that has the policy of MPOL_INTERLEAVE then the interleaving of pages may be destroyed. This patch fixes that by generating a fake address for each alloc_page_vma which will result is a distribution of pages as prescribed by MPOL_INTERLEAVE. Lee also noted that the sequence of nodes for the new pages seems to be inverted. So we also invert the way the lists of pages for migration are build. Signed-off-by:

Right at the moment (thanks to a patch from Andrew), cpu_possible_map on voyager is CPU_MASK_NONE, which means the machine always thinks it has no CPUs. Fix that by doing an early initialisation of the cpu_possible_map from the cpu_phys_present_map. (akpm: we aim to please) Signed-off-by:

EGA boards suck: they mostly have write-only registers. This is particularly problematic for the overflow register: for being able to write to it, we would have to handle vertical sync & such too, which (I'd say) would potentially break a lot of configurations. Instead, just disabling vertical resize for EGA boards is just nice enough (horizontal resize still works). Fixes http://bugzilla.kernel.org/show_bug.cgi?id=6106Signed-off-by:

To avoid conflicts, in kernel files errno is expanded to kernel_errno, to distinguish it from glibc errno. In this case, the code wants to use the libc errno but the kernel one is used; in the other usage, we return errno in place of -errno in case of an error. Signed-off-by:

Fix and update for gcc-4.0. - arch/m32r/kernel/signal.c: Change type of the 8th parameter of sys_rt_sigsuspend() from 'struct pt_regs' to 'struct pt_regs *'. This functions make use of the 'regs' parameter to return status value, but gcc-4.0 optimizes and removes it as a dead code. Functions, sys_sigaltstack() and sys_rt_sigreturn(), have also modified. - arch/m32r/lib/usercopy.c, include/asm-m32r/uaccess.h: Add early-clobber constraints('&') to output values of asm statements; these constraints seems to be required for gcc-4.0 register assignment.

Add -O2 option to AFLAGS to enable asm code optimization for m32r. On m32r gas, "-m32r2 -O" option enables assembler's parallel code generation optimization for M32R2 ISA as a default. So, "-no-parallel" option is required explicitly for a cpu core with single instuction issuing, for example, VDEC2. Signed-off-by:
