2009-03-11x86: remove zImage supportH. Peter Anvin
Impact: obsolete feature removal The zImage kernel format has been functionally unused for a very long time. It is just barely possible to build a modern kernel that still fits within the zImage size limit, but it is highly unlikely that anyone ever uses it. Furthermore, although it is still supported by most bootloaders, it has been at best poorly tested (or not tested at all); some bootloaders are even known to not support zImage at all and not having even noticed. Also remove some really obsolete constants that no longer have any meaning. LKML-Reference: <49B703D4.1000008@zytor.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2009-01-14x86: headers cleanup - boot.hCyrill Gorcunov
Impact: cleanup 'make headers_check' warn us about leaking of kernel private (mostly compile time vars) data to userspace in headers. Fix it. Neither BOOT_HEAP_SIZE, BOOT_STACK_SIZE refs was found by searching thru net (ie in user-space area) so fence this all by __KERNEL__ guard.

2009-01-04bzip2/lzma: x86 kernel compression supportAlain Knaff
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.

2008-10-22x86: Fix ASM_X86__ header guardsH. Peter Anvin
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
