functionality, building upon the new layout introduced in mod xfs-linux:xfs-kern:207390a. The new multi-level extent allocations are only required for heavily fragmented files, so the old-style linear extent list is used on files until the extents reach a pre-determined size of 4k. 4k buffers are used because this is the system page size on Linux i386 and systems with larger page sizes don't seem to gain much, if anything, by using their native page size as the extent buffer size. Also, using 4k extent buffers everywhere provides a consistent interface for CXFS across different platforms. The 4k extent buffers are managed by an indirection array (xfs_ext_irec_t) which is basically just a pointer array with a bit of extra information to keep track of the number of extents in each buffer as well as the extent offset of each buffer. Major changes include: - Add multi-level in-core file extent functionality to the xfs_iext_ subroutines introduced in mod: xfs-linux:xfs-kern:207390a - Introduce 13 new subroutines which add functionality for multi-level in-core file extents: xfs_iext_add_indirect_multi() xfs_iext_remove_indirect() xfs_iext_realloc_indirect() xfs_iext_indirect_to_direct() xfs_iext_bno_to_irec() xfs_iext_idx_to_irec() xfs_iext_irec_init() xfs_iext_irec_new() xfs_iext_irec_remove() xfs_iext_irec_compact() xfs_iext_irec_compact_pages() xfs_iext_irec_compact_full() xfs_iext_irec_update_extoffs() SGI-PV: 928864 SGI-Modid: xfs-linux-melb:xfs-kern:207393a Signed-off-by: NMandy Kirkconnell <alkirkco@sgi.com> Signed-off-by: NNathan Scott <nathans@sgi.com>

code to prepare for an upcoming mod which will introduce multi-level in-core extent allocations. Although the in-core extent management is using a new code path in this mod, the functionality remains the same. Major changes include: - Introduce 10 new subroutines which re-orgainze the existing code but do NOT change functionality: xfs_iext_get_ext() xfs_iext_insert() xfs_iext_add() xfs_iext_remove() xfs_iext_remove_inline() xfs_iext_remove_direct() xfs_iext_realloc_direct() xfs_iext_direct_to_inline() xfs_iext_inline_to_direct() xfs_iext_destroy() - Remove 2 subroutines (functionality moved to new subroutines above): xfs_iext_realloc() -replaced by xfs_iext_add() and xfs_iext_remove() xfs_bmap_insert_exlist() - replaced by xfs_iext_insert() xfs_bmap_delete_exlist() - replaced by xfs_iext_remove() - Replace all hard-coded (indexed) extent assignments with a call to xfs_iext_get_ext() - Replace all extent record pointer arithmetic (ep++, ep--, base + lastx,..) with calls to xfs_iext_get_ext() - Update comments to remove the idea of a single "extent list" and introduce "extent record" terminology instead SGI-PV: 928864 SGI-Modid: xfs-linux-melb:xfs-kern:207390a Signed-off-by: NMandy Kirkconnell <alkirkco@sgi.com> Signed-off-by: NNathan Scott <nathans@sgi.com>

EM64T CPUs have somewhat weird error reporting for non canonical RIPs in SYSRET. We can't handle any exceptions there because the exception handler would end up running on the user stack which is unsafe. To avoid problems any code that might end up with a user touched pt_regs should return using int_ret_from_syscall. int_ret_from_syscall ends up using IRET, which allows safe exceptions.

This patch removes the reliance of iwmmxt on hand coded alignments. Since thread_info is always 8K aligned, specifying that fpstate is 8-byte aligned achieves the same effect without needing to resort to hand coded alignments. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
