2008-07-28sh: Conditionally re-enable IRQs in fault path.Stuart Menefy
The current kernel behaviour is to reenable interrupts unconditionally when taking a page fault. This patch changes this to only enable them if interrupts were previously enabled. It also fixes a problem seen with this fix in place: the kernel previously flushed the vsyscall page when handling a signal, which is not only unncessary, but caused a possible sleep with interrupts disabled.

2008-07-28sh: Add support for 16kB PAGE_SIZE.Paul Mundt
16kB is a useful size on nommu, while 64kB still tends to be too big to be useful. Newer MMUs are likely to support this as well, so plug it in in anticipation of those, too. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-07-28sh: Support variable page sizes on nommu.Paul Mundt

2008-07-28binfmt_elf_fdpic: Magical stack pointer index, for NEW_AUX_ENT compat.Paul Mundt
While implementing binfmt_elf_fdpic on SH it quickly became apparent that SH was the first platform to support both binfmt_elf_fdpic and binfmt_elf, as well as the only of the FDPIC platforms to make use of the auxvt. Currently binfmt_elf_fdpic uses a special version of NEW_AUX_ENT() where the first argument is the entry displacement after csp has been adjusted, being reset after each adjustment. As we have no ability to sort this out through the platform's ARCH_DLINFO, this index needs to be managed entirely in create_elf_fdpic_tables(). Presently none of the platforms that set their own auxvt entries are able to do so through their respective ARCH_DLINFOs when using binfmt_elf_fdpic. In addition to this, binfmt_elf_fdpic has been looking at DLINFO_ARCH_ITEMS for the number of architecture-specific entries in the auxvt. This is legacy cruft, and is not defined by any platforms in-tree, even those that make heavy use of the auxvt. AT_VECTOR_SIZE_ARCH is always available, and contains the number that is of interest here, so we switch to using that unconditionally as well. As this has direct bearing on how much stack is used, platforms that have configurable (or dynamically adjustable) NEW_AUX_ENT calls need to either make AT_VECTOR_SIZE_ARCH more fine-grained, or leave it as a worst-case and live with some lost stack space if those entries aren't pushed (some platforms may also need to purposely sacrifice some space here for alignment considerations, as noted in the code -- although not an issue for any FDPIC-capable platform today).

Segmentation fault mount $MOUNT_FORCE_OPT -n -o remount,ro -t dummytype dummydev / 2> /dev/null The new super.c:nfs_remount function doesn't check the validity of the options/options4 pointers. Unfortunately, this seems to happend. The obvious patch seems to check the pointers, and not to do anything if the happend to be NULL. Tested on an XScale PXA255 system, latest git. Regards, M.

2008-07-27x86: fix cpu hotplug on 32bitThomas Gleixner
commit 3e9704739daf46a8ba6593d749c67b5f7cd633d2 ("x86: boot secondary cpus through initial_code") causes the kernel to crash when a CPU is brought online after the read only sections have been write protected. The write to initial_code in do_boot_cpu() fails. Move inital_code to .cpuinit.data section. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: H. Peter Anvin <hpa@zytor.com>
