Remove CACHE_ALL_LOOP2 macro because it is identical to CACHE_ALL_LOOP 2. Change BUG_ON to WARN_ON 3. Remove end aligned from CACHE_LOOP_LIMITS. C implementation do not need aligned end address and ASM code do aligned in their macros 4. ASM optimized CACHE_RANGE_LOOP_1/2 macros needs to get aligned end address. Because end address is compound from start + size, end address is the first address which is exclude. Here is the corresponding code which describe it. + int align = ~(line_length - 1); + end = ((end & align) == end) ? end - line_length : end & align; a) end is aligned: it is necessary to subtruct line length because we don't want to work with next cacheline b) end address is not aligned: Just align it to be ready for ASM code.

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>
