| * xen: use mmu_update for xen_set_pte_at()Jeremy Fitzhardinge2011-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In principle update_va_mapping is a good match for set_pte_at, since it gets the address being mapped, which allows Xen to use its linear pagetable mapping. However that assumes that the pmd for the address is attached to the current pagetable, which may not be true for a given user address space because the kernel pmd is not shared (at least on 32-bit guests). Normally the kernel will automatically sync a missing part of the pagetable with the init_mm pagetable transparently via faults, but that fails when a missing address is passed to Xen. And while the linear pagetable mapping is very useful for 32-bit Xen (as it avoids an explicit domain mapping), 32-bit Xen is deprecated. 64-bit Xen has all memory mapped all the time, so it makes no real difference. The upshot is that we should use mmu_update, since it can operate on non-current pagetables or detached pagetables. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

* | selinux: don't pass in NULL avd to avc_has_perm_noauditLinus Torvalds2011-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now security_get_user_sids() will pass in a NULL avd pointer to avc_has_perm_noaudit(), which then forces that function to have a dummy entry for that case and just generally test it. Don't do it. The normal callers all pass a real avd pointer, and this helper function is incredibly hot. So don't make avc_has_perm_noaudit() do conditional stuff that isn't needed for the common case. This also avoids some duplicated stack space.

I found it useful for multi-commands/reset workflows with the same slave on a multi-slave bus. This DS2408 w1 slave driver is not complete for all the features of the chip, but its sufficient if you use it as a simple IO expander. Enjoy! The ds1wm had Kconfig dependencies towards ARM && HAVE_CLK. I took them out since I was using the ds1wm on an x86_64 platform (ds1wm in a FPGA through pcie) and found them irrelevant. The clock freq/divisors at the top of ds1wm.c did not have the MSB set to 1. This bit is CLK_EN which turns the whole prescaler and dividers on. The driver never mentionned this bit either, so I just included this bit right in the table entries. I also took the liberty to add a couple of entries to the table. The spec doesn't explicitely mentions these possibilities but the description and examination of the core shows the prescalers & dividers can be used for more than the table explicitely shows. The table I enlarged still doesn't cover all possibilities, but it's a good start. I also made a few tweaks to a couple of the read and write algorithms which made sense while I had my head very deep in the ds1wm documentation. We stressed it a lot with 10+ slaves on the bus, many ds2408, ds2431 and ds2433 at the same time doing extensive interaction. It proved quite stable in our production environment.
