2007-06-26[MIPS] EMMA2RH: Disable GEN_RTC, it can't possibly work.Ralf Baechle
Neither rtc_mips_get_time nor rtc_mips_set_time are being initialized by the EMMA2RH setup code, so genrtc at best was a RTC dummy avoiding a few error messages but not providing actual functionality. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-06-24ACPI: preserve the ebx value in acpi_copy_wakeup_routineTian Kevin
Register %ebx serves as the "global offset table base register" for position-independent code. For absolute code, %ebx serves as a local register and has no specified role in the function calling sequence. In either case, a function must preserve the register value for the caller. acpi_copy_wakeup_routine overrides %ebx without saving it, this may corrupt the called data. Kevin found that most time the value of Sx is saved in %esi, however sometimes compiler also uses %ebx. When this happens, suspends fails since sleep value in ebx is changed by acpi_copy_wakeup_routine. The same funtion in X86_64 doesn't have this problem.

2007-06-24x86_64: fix misplaced `continue' in mce.cJoshua Wise
Background: When a userspace application wants to know about machine check events, it opens /dev/mcelog and does a read(). Usually, we found that this interface works well, but in some cases, when the system was taking large numbers of machine check exceptions, the read() would hang. The system would output a soft-lockup warning, and the daemon reading from /dev/mcelog would suck up as much of a single CPU as it could spinning in system space. Description: This patch fixes this bug. In particular, there was a "continue" inside a timeout loop that presumably was intended to break out of the outer loop, but instead caused the inner loop to continue. This patch also makes the condition for the break-out a little more evident by changing a !time_before to a time_after_eq. Result: The read() no longer hangs in this test case. Testing: On my system, I could replicate the bug with the following command: # for i in `seq 15000`; do ./inject_sbe.sh; done where inject_sbe.sh contains commands to inject a single-bit error into the next memory write transaction. Patch: This patch is against git f1518a088bde6aea49e7c472ed6ab96178fcba3e.

2007-06-24alpha: fix alignment problem in csum_ipv6_magic()Ivan Kokshaysky
Hopefully this fixes http://bugzilla.kernel.org/show_bug.cgi?id=8635 The struct in6_addr passed to csum_ipv6_magic() is 4 byte aligned, so we can't use the regular 64-bit loads. Since the cost of handling of 4 byte and 1 byte aligned 64-bit data is roughly the same, this code can cope with any src/dst [mis]alignment.

2007-06-23[AVR32] Fix bug in invalidate_dcache_region()Haavard Skinnemoen
If (start + size) is not cacheline aligned and (start & mask) > (end & mask), the last but one cacheline won't be invalidated as it should. Fix this by rounding `end' down to the nearest cacheline boundary if it gets adjusted due to misalignment. Also flush the write buffer unconditionally -- if the dcache wrote back a line just before we invalidated it, the dirty data may be sitting in the write buffer waiting to corrupt our buffer later.

2007-06-22x86_64: Ignore compat mode SYSCALL when IA32_EMULATION is not definedAndi Kleen

2007-06-22i386: Make CMPXCHG64 only dependent on PAEAndi Kleen
It is only used for PAE kernels in set_64bit. The problem is that due to a old Windows bug many CPUs need magic MSRs to enable CMPXCHG64, and we can't do that nicely early enough before it is potentially used. But since we only need it in PAE kernels so only force the checking for CMPXCHG65 with PAE.

The "is_exec" branch of the protection check in do_page_fault() didn't do anything on 32-bit PowerPC. So if a userland program jumps to a page with Linux protection flags "---p", all the tests happily fall through, and handle_mm_fault() is called, which in turn calls handle_pte_fault(), which calls update_mmu_cache(), which goes flush the dcache to a page with no access rights.

2007-06-16uml: remove PAGE_SIZE from libc codeJeff Dike
Distros seem to be removing PAGE_SIZE from asm/page.h. So, the libc side of UML should stop using it. I replace it with UM_KERN_PAGE_SIZE, which is defined to be the same as PAGE_SIZE on the kernel side of the house. I could also use getpagesize(), but it's more important that UML have the same value of PAGE_SIZE everywhere. It's conceivable that it could be built with a larger PAGE_SIZE, and use of getpagesize() would break that badly. PAGE_MASK got the same treatment, as it is closely tied to PAGE_SIZE.
