2010-08-02ARM: 6212/1: atomic ops: add memory constraints to inline asmWill Deacon
commit 398aa66827155ef52bab58bebd24597d90968929 upstream. 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.

2010-08-02ARM: 6211/1: atomic ops: fix register constraints for atomic64_add_unlessWill Deacon
commit 068de8d1be48a04b92fd97f76bb7e113b7be82a8 upstream. 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.

commit 2503a5ecd86c002506001eba432c524ea009fe7f upstream. RealView boards with certain revisions of the L220 cache controller (ARM11* processors only) may have issues (hardware deadlock) with the recent changes to the mb() barrier implementation (DSB followed by an L2 cache sync).

2010-08-02Input: twl40300-keypad - fix handling of "all ground" rowsDmitry Torokhov
commit 3fea60261e73dbf4a51130d40cafcc8465b0f2c3 upstream. The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c) defines a key map for the matrix keypad keyboard. The hardware seems to use all of the 8 rows and 8 columns of the keypad, although not all possible locations are used. The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix. Unfortunately we do not allocate enough space and end up owerwriting some random memory.

2010-08-02ARM: 6205/1: perf: ensure counter delta is treated as unsignedWill Deacon
commit 446a5a8b1eb91a6990e5c8fe29f14e7a95b69132 upstream. Hardware performance counters on ARM are 32-bits wide but atomic64_t variables are used to represent counter data in the hw_perf_event structure. The armpmu_event_update function right-shifts a signed 64-bit delta variable and adds the result to the event count. This can lead to shifting in sign-bits if the MSB of the 32-bit counter value is set. This results in perf output such as: Performance counter stats for 'sleep 20': 18446744073460670464 cycles <-- 0xFFFFFFFFF12A6000 7783773 instructions # 0.000 IPC 465 context-switches 161 page-faults 1172393 branches 20.154242147 seconds time elapsed This patch ensures that the delta value is treated as unsigned so that the right shift sets the upper bits to zero.

commit 9a40ac86152c9cffd3dca482a15ddf9a8c5716b3 upstream. When functions incoming parameters are not in input operands list gcc 4.5 does not load the parameters into registers before calling this function but the inline assembly assumes valid addresses inside this function. This breaks the code because r0 and r1 are invalid when execution enters v4wb_copy_user_page () Also the constant needs to be used as third input operand so account for that as well.

2010-05-01ARM: 6066/1: Fix "BUG: scheduling while atomic: swapper/0/0x00000002Santosh Shilimkar
This patch fixes the preempt leak in the cpuidle path invoked from cpu-hotplug. The fix is suggested by Russell King and is based on x86 idea of calling init_idle() on the idle task when it's re-used which also resets the preempt count amongst other things dump: BUG: scheduling while atomic: swapper/0/0x00000002 Modules linked in: Backtrace: [<c0024f90>] (dump_backtrace+0x0/0x110) from [<c0173bc4>] (dump_stack+0x18/0x1c) r7:c02149e4 r6:c033df00 r5:c7836000 r4:00000000 [<c0173bac>] (dump_stack+0x0/0x1c) from [<c003b4f0>] (__schedule_bug+0x60/0x70) [<c003b490>] (__schedule_bug+0x0/0x70) from [<c0174214>] (schedule+0x98/0x7b8) r5:c7836000 r4:c7836000 [<c017417c>] (schedule+0x0/0x7b8) from [<c00228c4>] (cpu_idle+0xb4/0xd4) # [<c0022810>] (cpu_idle+0x0/0xd4) from [<c0171dd8>] (secondary_start_kernel+0xe0/0xf0) r5:c7836000 r4:c0205f40 [<c0171cf8>] (secondary_start_kernel+0x0/0xf0) from [<c002d57c>] (prm_rmw_mod_reg_bits+0x88/0xa4) r7:c02149e4 r6:00000001 r5:00000001 r4:c7836000 Backtrace aborted due to bad frame pointer <c7837fbc> Cc: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The switch to using GPIOLIB broke the sd/mmc card detection on the RealView development boards if GPIO_PL061 was not selected. This patch selects GPIO_PL061 if GPIOLIB is selected. The sense of the return value from mmc_status has also changed and is corrected.
