* bzip2/lzma: make config machinery an arch configurableH. Peter Anvin2009-01-051-0/+3
| | | | | | | | | | Impact: Bug fix (we should not show this menu on irrelevant architectures) Make the config machinery to drive the gzip/bzip2/lzma selection dependent on the architecture advertising HAVE_KERNEL_* so that we don't display this for architectures where it doesn't matter. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* bzip2/lzma: x86 kernel compression supportAlain Knaff2009-01-053-107/+44
| | | | | | | | | | | | | | | | | | | | | | | | | Impact: Replaces x86 kernel decompressor with new code This is the third part of the bzip2/lzma patch The bzip patch is based on an idea by Christian Ludwig, includes support for compressing the kernel with bzip2 or lzma rather than gzip. Both compressors give smaller sizes than gzip. Lzma's decompresses faster than bzip2. It also supports ramdisks and initramfs' compressed using these two compressors. The functionality has been successfully used for a couple of years by the udpcast project This version applies to "tip" kernel 2.6.28 This part contains: - support for new bzip2 and lzma kernel compression for x86 Signed-off-by: Alain Knaff <alain@knaff.lu> Signed-off-by: H.

| | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup __alloc_bootmem and __alloc_bootmem_node do panic for us in case of fail so no need for additional checks here.

| | | | | | | | | | | | | | | | | | | | | | Impact: Reduce inter-node memory traffic.

| * cpumask: convert shared_cpu_map in acpi_processor* structs to cpumask_var_tRusty Russell2009-01-033-12/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: Reduce memory usage, use new API. This is part of an effort to reduce structure sizes for machines configured with large NR_CPUS. cpumask_t gets replaced by cpumask_var_t, which is either struct cpumask[1] (small NR_CPUS) or struct cpumask * (large NR_CPUS).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: Reduce future system panics due to cpumask operations using NR_CPUS Insure that code does not look at bits >= nr_cpu_ids as when cpumasks are allocated based on nr_cpu_ids, these extra bits will not be defined. Also some other minor updates: * change in to use cpu accessor function set_cpu_present() instead of directly accessing cpu_present_map w/cpu_clear() [arch/x86/kernel/reboot.c] * use cpumask_of() instead of &cpumask_of_cpu() [arch/x86/kernel/reboot.c] * optimize some cpu_mask_to_apicid_and functions.
