* [IA64] Export three symbols for module useZhang, Xiantao2008-02-043-11/+20
| | | | | | | | Since kvm/module needs to use some unexported functions in kernel, so export them with this patch. Signed-off-by: Zhang Xiantao <xiantao.zhang@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

* [IA64] efi.c Add /* never reached */ annotationAron Griffis2008-02-041-2/+2
| | | | | | | | As written, this loop could be for (;;) instead of do while (md). The tests inside the loop always result in a return so the loop never terminates normally. Signed-off-by: Aron Griffis <aron@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] efi.c Spelling/punctuation fixesAron Griffis2008-02-041-8/+8

* [IA64] Make efi.c mostly fit in 80 columnsAron Griffis2008-02-041-223/+266
| | | | | | | | | | This patch is purely whitespace changes to make the code fit in 80 columns, plus fix some inconsistent indentation. The efi_guidcmp() tests remain wider than 80-columns since that seems to be the most clear. Signed-off-by: Aron Griffis <aron@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] aliasing-test: fix gcc warnings on non-ia64Randy Dunlap2008-02-041-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Eliminate all build warnings. OK, these build warnings are from a build on x86_64. When I build on ia64, I don't see warnings. Now builds cleanly on ia64 and x86_64.

* [IA64] Slim-down __clear_bit_unlockZoltan Menyhart2008-02-041-22/+28
| | | | | | | | | | | | | | | | - I removed the unnecessary barrier() from __clear_bit_unlock(). ia64_st4_rel_nta() makes sure all the modifications are globally seen before the bit is seen to be off. - I made __clear_bit() modeled after __set_bit() and __change_bit(). - I corrected some comments sating that a memory barrier is provided, yet in reality, it is the acquisition side of the memory barrier only. - I corrected some comments, e.g. test_and_clear_bit() was peaking about "bit to set".

| | | | | | | | | | | Fixes userspace build errors when linux/ipv6.h is included such as in the dhcpv6 package under fedora. Likely causes other userspace build errors as well.

| * x86: use the pfn from the page when change its attributesArjan van de Ven2008-02-041-14/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When changing the attributes of a pte, we should use the PFN from the existing PTE rather than going through hoops calculating what we think it might have been; this is both fragile and totally unneeded. It also makes it more hairy to call any of these functions on non-direct maps for no good reason whatsover. With this change, __change_page_attr() no longer takes a pfn as argument, which simplifies all the callers.

| * x86: teach the static_protection function about high mappingsArjan van de Ven2008-02-041-4/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, enforcing that the high mapping of the kernel text doesn't get the NX bit is done deep in the guts of CPA, rather than in the static_protection() function that enforces all other per-arch sanity checks. This patch moves this sanity check into the central static_protection() function instead, and makes it apply ONLY to the kernel text, not to all other areas in the high mapping.
