header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of  where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

Remove the apparently useless config option GENERIC_BUST_SPINLOCK,
since nothing in the source tree refers to it.

[PATCH] x86: deflate stack usage in lib/inflate.c

2007-05-02T17:27:15+00:00

inflate_fixed and huft_build together use around 2.7k of stack.  When
using 4k stacks, I saw stack overflows from interrupts arriving while
unpacking the root initrd:

do_IRQ: stack overflow: 384
 [] show_trace_log_lvl+0x1a/0x30
 [] show_trace+0x12/0x14
 [] dump_stack+0x16/0x18
 [] do_IRQ+0x6d/0xd9
 [] xen_evtchn_do_upcall+0x6e/0xa2
 [] xen_hypervisor_callback+0x25/0x2c
 [] xen_restore_fl+0x27/0x29
 [] _spin_unlock_irqrestore+0x4a/0x50
 [] change_page_attr+0x577/0x584
 [] kernel_map_pages+0x8d/0xb4
 [] cache_alloc_refill+0x53f/0x632
 [] __kmalloc+0xc1/0x10d
 [] malloc+0x10/0x12
 [] huft_build+0x2a7/0x5fa
 [] inflate_fixed+0x91/0x136
 [] unpack_to_rootfs+0x5f2/0x8c1
 [] populate_rootfs+0x1e/0xe4

(This was under Xen, but there's no reason it couldn't happen on bare
  hardware.)

This patch mallocs the local variables, thereby reducing the stack
usage to sane levels.

Also, up the heap size for the kernel decompressor to deal with the
extra allocation.

[PATCH] disable init/initramfs.c: architectures

2007-02-11T18:51:25+00:00

Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs
when CONFIG_BLK_DEV_INITRAMFS is not selected.  This saves another 4 kbytes
on most platfoms (some reserve PAGE_SIZE for initramfs).
