We essentially treat userspace as an entirely separate environment which isn't relevant to lockdep (lockdep doesn't monitor userspace.) We don't tell lockdep that IRQs will be enabled in that environment. Instead, when creating kernel threads (which is a rare event compared to entering/leaving userspace) we have to update the lockdep state. Do this by starting threads with IRQs disabled, and in the kthread helper, tell lockdep that IRQs are enabled, and enable them. This provides lockdep with a consistent view of the current IRQ state in kernel space. This also revert portions of 0d928b0b616d1c5c5fe76019a87cba171ca91633 which didn't fix the problem.

| * ARM: 6212/1: atomic ops: add memory constraints to inline asmWill Deacon2010-07-091-66/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the 32-bit and 64-bit atomic operations on ARM do not include memory constraints in the inline assembly blocks. In the case of barrier-less operations [for example, atomic_add], this means that the compiler may constant fold values which have actually been modified by a call to an atomic operation. This issue can be observed in the atomic64_test routine in <kernel root>/lib/atomic64_test.c: 00000000 <test_atomic64>: 0: e1a0c00d mov ip, sp 4: e92dd830 push {r4, r5, fp, ip, lr, pc} 8: e24cb004 sub fp, ip, #4 c: e24dd008 sub sp, sp, #8 10: e24b3014 sub r3, fp, #20 14: e30d000d movw r0, #53261 ; 0xd00d 18: e3011337 movw r1, #4919 ; 0x1337 1c: e34c0001 movt r0, #49153 ; 0xc001 20: e34a1aa3 movt r1, #43683 ; 0xaaa3 24: e16300f8 strd r0, [r3, #-8]! 28: e30c0afe movw r0, #51966 ; 0xcafe 2c: e30b1eef movw r1, #48879 ; 0xbeef 30: e34d0eaf movt r0, #57007 ; 0xdeaf 34: e34d1ead movt r1, #57005 ; 0xdead 38: e1b34f9f ldrexd r4, [r3] 3c: e1a34f90 strexd r4, r0, [r3] 40: e3340000 teq r4, #0 44: 1afffffb bne 38 <test_atomic64+0x38> 48: e59f0004 ldr r0, [pc, #4] ; 54 <test_atomic64+0x54> 4c: e3a0101e mov r1, #30 50: ebfffffe bl 0 <__bug> 54: 00000000 .word 0x00000000 The atomic64_set (0x38-0x44) writes to the atomic64_t, but the compiler doesn't see this, assumes the test condition is always false and generates an unconditional branch to __bug. The rest of the test is optimised away. This patch adds suitable memory constraints to the atomic operations on ARM to ensure that the compiler is informed of the correct data hazards. We have to use the "Qo" constraints to avoid hitting the GCC anomaly described at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44492 , where the compiler makes assumptions about the writeback in the addressing mode used by the inline assembly. These constraints forbid the use of auto{inc,dec} addressing modes, so it doesn't matter if we don't use the operand exactly once.

| * ARM: 6211/1: atomic ops: fix register constraints for atomic64_add_unlessWill Deacon2010-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The atomic64_add_unless function compares an atomic variable with a given value and, if they are not equal, adds another given value to the atomic variable. The function returns zero if the addition did not occur and non-zero otherwise. On ARM, the return value is initialised to 1 in C code. Inline assembly code then performs the atomic64_add_unless operation, setting the return value to 0 iff the addition does not occur. This means that when the addition *does* occur, the value of ret must be preserved across the inline assembly and therefore requires a "+r" constraint rather than the current one of "=&r". Thanks to Nicolas Pitre for helping to spot this.

Recent changes cause problems with how we calculate the start address, it was always adding the RMO into the start address which is incorrect. This patch only adds in the RMO offset if we are in the kexec code path, as it needs the RMO to work correctly. Instead of adding the RMO offset in in the common code path, we can just set r6 to the RMO offset in the kexec code path instead of to zero, and finally perform the masking in the common code path Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

But this leaves some pins uninitialized, and they'll be never recovered after resume. This patch adds the proper recovery of cleared pin controls on resume. Also it adds a check of bus->shutdown so that pins won't be cleared at module unloading.

Thus, the IGNORE quirk (0x0004) cannot be used to stop usbhid from binding devices like iBuddy, which has been recently removed from the ignore list due to product ID conflict. This patch adds the user quirk check to hid_add_device(), and makes hid_add_device() return -ENODEV when HID_QUIRK_IGNORE bit is set. HID_QUIRK_NO_IGNORE still takes precedence over HID_QUIRK_IGNORE.
