The patch titled include/asm-generic/vmlinux.lds.h: make readmostly section correctly align has been removed from the -mm tree. Its filename was include-asm-generic-vmlinuxldsh-make-readmostly-section-correctly-align.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: include/asm-generic/vmlinux.lds.h: make readmostly section correctly align From: Shaohua Li <shaohua.li@xxxxxxxxx> The readmostly section should end at a cacheline aligned address, otherwise the last several data might share cachline with other data and make the readmostly data still have cache bounce. For example, in ia64, secpath_cachep is the last readmostly data, and it shares cacheline with init_uts_ns. a000000100e80480 d secpath_cachep a000000100e80488 D init_uts_ns Signed-off-by: Shaohua Li <shaohua.li@xxxxxxxxx> Cc: "H.
