On a CPU with aliases the IDE core needs to flush caches in the special IDE variants of insw, insl etc. If IDE support is built as a module this will only work if local_flush_data_cache_page happens is exported as a module.

2006-12-10[PATCH] fdtable: Make fdarray and fdsets equal in sizeVadim Lobanov
Currently, each fdtable supports three dynamically-sized arrays of data: the fdarray and two fdsets. The code allows the number of fds supported by the fdarray (fdtable->max_fds) to differ from the number of fds supported by each of the fdsets (fdtable->max_fdset). In practice, it is wasteful for these two sizes to differ: whenever we hit a limit on the smaller-capacity structure, we will reallocate the entire fdtable and all the dynamic arrays within it, so any delta in the memory used by the larger-capacity structure will never be touched at all. Rather than hogging this excess, we shouldn't even allocate it in the first place, and keep the capacities of the fdarray and the fdsets equal. This patch removes fdtable->max_fdset. As an added bonus, most of the supporting code becomes simpler.

2006-12-10[SPARC64]: Fix several kprobes bugs.David S. Miller
- relbranch_fixup(), for non-branches, would end up setting regs->tnpc incorrectly, in fact it would set it equal to regs->tpc which would cause that instruction to execute twice Also, if this is not a PC-relative branch, we should just leave regs->tnpc as-is. This covers cases like 'jmpl' which branch to absolute values. - To be absolutely %100 safe, we need to flush the instruction cache for all assignments to kprobe->ainsn.insn[], including cases like add_aggr_kprobe() - prev_kprobe's status field needs to be 'unsigned long' to match the type of the value it is saving - jprobes were totally broken: = jprobe_return() can run in the stack frame of the jprobe handler, or in an even deeper stack frame, thus we'll be in the wrong register window than the one from the original probe state. So unwind using 'restore' instructions, if necessary, right before we do the jprobe_return() breakpoint trap. = There is no reason to save/restore the register window saved at %sp at jprobe trigger time. Those registers cannot be modified by the jprobe handler. Also, this code was saving and restoring "sizeof (struct sparc_stackf)" bytes. Depending upon the caller, this could clobber unrelated stack frame pieces if there is only a basic 128-byte register window stored on the stack, without the argument save area. So just saving and restoring struct pt_regs is sufficient. = Kill the "jprobe_saved_esp", totally unused. Also, delete "jprobe_saved_regs_location", with the stack frame unwind now done explicitly by jprobe_return(), this check is superfluous. Signed-off-by: David S. Miller <davem@davemloft.net>

2006-12-09[PATCH] x86: Fix boot hang due to nmi watchdog init codeRavikiran G Thirumalai
2.6.19 stopped booting (or booted based on build/config) on our x86_64 systems due to a bug introduced in 2.6.19. check_nmi_watchdog schedules an IPI on all cpus to busy wait on a flag, but fails to set the busywait flag if NMI functionality is disabled. This causes the secondary cpus to spin in an endless loop, causing the kernel bootup to hang. Depending upon the build, the busywait flag got overwritten (stack variable) and caused the kernel to bootup on certain builds. Following patch fixes the bug by setting the busywait flag before returning from check_nmi_watchdog. I guess using a stack variable is not good here as the calling function could potentially return while the busy wait loop is still spinning on the flag.
