2008-03-07x86-boot: don't request VBE2 informationPeter Korsgaard2-10/+1
The new x86 setup code (4fd06960f120) broke booting on an old P3/500MHz with an onboard Voodoo3 of mine. After debugging it, it turned out to be caused by the fact that the vesa probing now asks for VBE2 data. Disassembing the video BIOS shows that it overflows the vesa_general_info structure when VBE2 data is requested because the source addresses for the information strings which get strcpy'ed to the buffer lie outside the 32K BIOS code (and hence contain long sequences of 0xff's).

The old setup code didn't ask for VBE2 info, and the new code doesn't actually do anything with the extra information, so the fix is to simply not request it.

convert_fxsr_to_user() in 2.6.24's i387_32.c did this, and convert_to_fxsr() also does the inverse, so I assume it's an oversight that it is no longer being done. [ mingo@elte.hu: we encode it this way because there's no space for the 'FPU Last Instruction Opcode' (->fop) field in the legacy user_i387_ia32_struct that PTRACE_GETFPREGS/PTRACE_SETFPREGS uses. it's probably pure legacy - i'd be surprised if any user-space relied on the FPU Last Opcode in any way.

2008-03-07x86: clear DF before calling signal handlerAurelien Jarno3-5/+5
The Linux kernel currently does not clear the direction flag before calling a signal handler, whereas the x86/x86-64 ABI requires that. Linux had this behavior/bug forever, but this becomes a real problem with gcc version 4.3, which assumes that the direction flag is correctly cleared at the entry of a function. This patches changes the setup_frame() functions to clear the direction before entering the signal handler.

2008-03-06[IA64] update efi region debugging to use MB, GB and TB as well as KBSimon Horman1-4/+22
When EFI_DEBUG is defined to a non-zero value in arch/ia64/kernel/efi.c, the efi memory regions are displayed. This patch enhances the display code in a few ways: 1. Use TB, GB and MB as well as KB as units. Although this introduces rounding errors (KB doesn't as size is always a multiple of 4Kb), it does make things a lot more readable. Also as the range is also shown, it is possible to note the exact size if it is important. In my experience, the size field is mostly useful for getting a general idea of the size of a region. On the rx2620 that I use, there actually is an 8TB region (though not backed by physical memory, and 8TB really is a lot more readable than 8589934592KB. 2. pad the size field with leading spaces to further improve readability ... ...

2008-03-05[S390] Get rid of memcpy gcc warning workaround.Heiko Carstens2-8/+7
Compile smp.o with -Wno-nonnull so gcc stops warning about memcpy being used with a null parameter. Also remove the workaround code and use a char * cast instead of a void * cast to do computations.

2008-03-05[S390] idle: Fix machine check handling in idle loop.Heiko Carstens2-2/+4
If a machine check handling is pending when the idle loop is entered default_idle will be left with timer ticks and virtual timer disabled. Fix this by "calling" the idle_chain. Also a BUG_ON(!in_interrupt) in start_hz_timer must be removed since the function now gets called from non interrupt context as well.

2008-03-04cris: correct usage of __user for copy to and from user space in ↵Jesper Nilsson2-2/+2
lib/usercopy and uaccess.h Function __copy_user_zeroing in arch/lib/usercopy.c had the wrong parameter set as __user, and in include/asm-cris/uaccess.h, it was not set at all for some of the calling functions. This will cut the number of warnings quite dramatically when using sparse. While we're here, remove useless CVS log and correct confusing typo.

2008-03-04alpha: make IOMMU respect the segment boundary limitsFUJITA Tomonori1-6/+34
This patch makes the IOMMU code not allocate a memory area spanning LLD's segment boundary. is_span_boundary() judges whether a memory area spans LLD's segment boundary. If iommu_arena_find_pages() finds such a area, it tries to find the next available memory area.

2008-03-04alpha: IOMMU had better access to the free space bitmap at only one placeFUJITA Tomonori1-13/+15
iommu_arena_find_pages duplicates the code to access to the bitmap for free space management. This patch convert the IOMMU code to have only one place to access the bitmap, in the popular way that other IOMMUs (e.g. POWER and SPARC) do.

2008-03-04CRIS: Import string.c (memcpy) from newlib: fixes compile error with gcc 4Jesper Nilsson2-317/+345
Adrian Bunk reported another compile error with a SVN head GCC: ... CC arch/cris/arch-v10/lib/string.o /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:138: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:138: error: lvalue required as increment operand /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:139: error: lvalue required as increment operand ... This is due to the use of the construct: *((long*)dst)++ = lc; Which isn't legal since casts don't return an lvalue. The solution is to import the implementation from newlib, which is continually autotested together with GCC mainline, and uses the construct: *(long *) dst = lc; dst += 4; Since this is an import of a file from newlib, I'm not touching the formatting or correcting any checkpatch errors. As for the earlier fix for memset.c, even if the two files for CRIS v10 and CRIS v32 are identical at the moment, it might be possible to tweak the CRIS v32 version. Thus, I'm not yet folding them into the same file, at least not until we've done some research on it.

2008-03-04Kprobes: indicate kretprobe support in KconfigAnanth N Mavinakayanahalli7-0/+13
Add CONFIG_HAVE_KRETPROBES to the arch/<arch>/Kconfig file for relevant architectures with kprobes support. This facilitates easy handling of in-kernel modules (like samples/kprobes/kretprobe_example.c) that depend on kretprobes being present in the kernel. Thanks to Sam Ravnborg for helping make the patch more lean. Per Mathieu's suggestion, added CONFIG_KRETPROBES and fixed up dependencies.

2008-03-04CRIS v10: Include mm.h instead of vmstat.h in kernel/time.cJesper Nilsson1-1/+1
Commit 2f569afd9ced9ebec9a6eb3dbf6f83429be0a7b4 (CONFIG_HIGHPTE vs. sub-page page tables) introduced use of inc_zone_page_state and dec_zone_page_state in include/linux/mm.h. Those are defined in include/linux/vmstat.h, but after it includes mm.h, making it impossible to include vmstat.h since inc_zone_page_state and dec_zone_page_state then would be undefined. arch/cris/arch-v10/kernel/time.c does just this, which makes the CRIS v10 build break with the following error: ... CC arch/cris/arch-v10/kernel/time.o In file included from include/linux/vmstat.h:7, from arch/cris/arch-v10/kernel/time.c:17: include/linux/mm.h: In function 'pgtable_page_ctor': include/linux/mm.h:902: error: implicit declaration of function 'inc_zone_page_state' include/linux/mm.h: In function 'pgtable_page_dtor': include/linux/mm.h:908: error: implicit declaration of function 'dec_zone_page_state' make[2]: *** [arch/cris/arch-v10/kernel/time.o] Error 1 make[1]: *** [arch/cris/arch-v10/kernel] Error 2 make: *** [sub-make] Error 2 ... By changing kernel/time.c to include linux/mm.h, the build succeeds.
