2009-01-16x86: fix assumed to be contiguous leaf page tables for kmap_atomic region ↵Jan Beulich
(take 2) Debugging and original patch from Nick Piggin <npiggin@suse.de> The early fixmap pmd entry inserted at the very top of the KVA is causing the subsequent fixmap mapping code to not provide physically linear pte pages over the kmap atomic portion of the fixmap (which relies on said property to calculate pte addresses). This has caused weird boot failures in kmap_atomic much later in the boot process (initial userspace faults) on a 32-bit PAE system with a larger number of CPUs (smaller CPU counts tend not to run over into the next page so don't show up the problem). Solve this by attempting to clear out the page table, and copy any of its entries to the new one. Also, add a bug if a nonlinear condition is encountered and can't be resolved, which might save some hours of debugging if this fragile scheme ever breaks again... Once we have such logic, we can also use it to eliminate the early ioremap trickery around the page table setup for the fixmap area. This also fixes potential issues with FIX_* entries sharing the leaf page table with the early ioremap ones getting discarded by early_ioremap_clear() and not restored by early_ioremap_reset(). It at once eliminates the temporary (and configuration, namely NR_CPUS, dependent) unavailability of early fixed mappings during the time the fixmap area page tables get constructed. Finally, also replace the hard coded calculation of the initial table space needed for the fixmap area with a proper one, allowing kernels configured for large CPU counts to actually boot.

2009-01-16m68k,m68knommu: merge header filesSam Ravnborg
Merge header files for m68k and m68knommu to the single location: arch/m68k/include/asm The majority of this patch was the result of the script that is included in the changelog below. The script was originally written by Arnd Bergman and exten by me to cover a few more files. When the header files differed the script uses the following: The original m68k file is named <file>_mm.h [mm for memory manager] The m68knommu file is named <file>_no.h [no for no memory manager] The files uses the following include guard: This include gaurd works as the m68knommu toolchain set the __uClinux__ symbol - so this should work in userspace too. Merging the header files for m68k and m68knommu exposes the (unexpected?) ABI differences thus it is easier to actually identify these and thus to fix them. The commit has been build tested with both a m68k and a m68knommu toolchain - with success. The commit has also been tested with "make headers_check" and this patch fixes make headers_check for m68knommu.

2009-01-16powerpc: Get the number of SLBs from "slb-size" propertyMichael Neuling
The PAPR says that the property for specifying the number of SLBs should be called "slb-size". We currently only look for "ibm,slb-size" because this is what firmware actually presents. This patch makes us look for the "slb-size" property as well and in preference to the "ibm,slb-size". This should future proof us if firmware changes to match PAPR.

2009-01-15alpha: fix RTC on marvelIvan Kokshaysky
Unlike other alphas, marvel doesn't have real PC-style CMOS clock hardware - RTC accesses are emulated via PAL calls. Unfortunately, for unknown reason these calls work only on CPU #0. So current implementation for arbitrary CPU makes CMOS_READ/WRITE to be executed on CPU #0 via IPI. However, for obvious reason this doesn't work with standard get/set_rtc_time() functions, where a bunch of CMOS accesses is done with disabled interrupts. Solved by making the IPI calls for entire get/set_rtc_time() functions, not for individual CMOS accesses. Which is also a lot more effective performance-wise. The patch is largely based on the code from Jay Estabrook. My changes: - tweak asm-generic/rtc.h by adding a couple of #defines to avoid a massive code duplication in arch/alpha/include/asm/rtc.h; - sys_marvel.c: fix get/set_rtc_time() return values (Jay's FIXMEs). NOTE: this fixes *only* LIB_RTC drivers. Legacy (CONFIG_RTC) driver wont't work on marvel. Actually I think that we should just disable CONFIG_RTC on alpha (maybe in 2.6.30?), like most other arches - AFAIK, all modern distributions use LIB_RTC anyway.

2009-01-15alpha: nautilus - fix hang on bootIvan Kokshaysky
Recently introduced generic pci_common_swizzle() relies on bus->self being NULL for the root PCI bus. But on nautilus bus->self points to the host bridge device, which is necessary as we do a root bus sizing on this system. As a result, pci_common_swizzle() loops infinitely. This worked until 2.6.29-rc1 because the alpha-specific swizzle routine checked for bus->parent == NULL (instead of bus->self). Fixed by clearing bus->self after bus sizing is done.

2009-01-15alpha: nautilus - fix compile failure with gcc-4.3Ivan Kokshaysky
init_srm_irq() deals with irq's #16 and above, but size of irq_desc array on nautilus and some other system types is 16. So gcc-4.3 complains that "array subscript is above array bounds", even though this function is never called on those systems. This adds a check for NR_IRQS <= 16, which effectively optimizes init_srm_irq() code away on problematic platforms. Thanks to Daniel Drake <dsd@gentoo.org> for detailed analysis of the problem.

And commit: ("allow stripping of generated symbols under CONFIG_KALLSYMS_ALL") 9bb482476c6c9d1ae033306440c51ceac93ea80c These stripping patches has caused a set of issues: 1) People have reported compatibility issues with binutils due to lack of support for `--strip-unneeded-symbols' with objcopy 2.15.92.0.2 Reported by: Wenji 2) ccache and distcc no longer works as expeced Reported by: Ted, Roland, + others 3) The installed modules increased a lot in size Reported by: Ted, Davej + others Reported-by: Wenji Huang <wenji.huang@oracle.com> Reported-by: "Theodore Ts'o" <tytso@mit.edu> Reported-by: Dave Jones <davej@redhat.com> Reported-by: Roland McGrath <roland@redhat.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2009-01-14x86, pat: fix reserve_memtype() for legacy 1MB rangeSuresh Siddha
Thierry Vignaud reported: > http://bugzilla.kernel.org/show_bug.cgi?id=12372 > > On P4 with an SiS motherboard (video card is a SiS 651) > X server fails to start with error: > xf86MapVidMem: Could not mmap framebuffer (0x00000000,0x2000) (Invalid > argument) Here X is trying to map first 8KB of memory using /dev/mem. Existing code treats first 0-4KB of memory as non-RAM and 4KB-8KB as RAM. Recent code changes don't allow to map memory with different attributes at the same time. Fix this by treating the first 1MB legacy region as special and always track the attribute requests with in this region using linear linked list (and don't bother if the range is RAM or non-RAM or mixed) Reported-and-tested-by: Thierry Vignaud <tvignaud@mandriva.com> Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-01-14[CVE-2009-0029] System call wrapper infrastructureHeiko Carstens
From: Martin Schwidefsky <schwidefsky@de.ibm.com> By selecting HAVE_SYSCALL_WRAPPERS architectures can activate system call wrappers in order to sign extend system call arguments. All architectures where the ABI defines that the caller of a function has to perform sign extension probably need this.

2009-01-14[CVE-2009-0029] Remove __attribute__((weak)) from sys_pipe/sys_pipe2Heiko Carstens
Remove __attribute__((weak)) from common code sys_pipe implemantation. IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations with the same name. Just rename them. For sys_pipe2 there is no architecture specific implementation. Cc: Richard Henderson <rth@twiddle.net> Cc: David S.

The new location suggested by Kumar Gala: as the driver is 83xx specific it's placed into arch/powerpc/platforms/83xx/.

2009-01-13powerpc/83xx: Make serial ports work on MPC8315E-RDB w/ FSL U-BootsAnton Vorontsov
FSL U-Boots use /soc8315@e0000000 node to search and fixup serial nodes' clock-frequency properties. Though in upstream kernels we use new naming convention -- for IMMR address space dts files specify /immr@e0000000 nodes. This makes FSL U-Boots fail to fixup the clock frequencies, and that leads to serial ports misbehaviour. We can workaround the issue by filling the clock frequency values manually. p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for ethernet nodes, so users should either change the .dts file locally or set MAC address via `ifconfig hw ether' command.
