memblock tests: Add memblock reset function Memblock simulator needs to be able to reset memblock data structures between different test cases.

memblock tests: add verbose output to memblock tests Add and use functions and macros for printing verbose testing output. If the Memblock simulator was compiled with VERBOSE=1: - prefix_push(): appends the given string to a prefix string that will be printed in test_fail() and test_pass*(). - prefix_pop(): removes the last prefix from the prefix string. - prefix_reset(): clears the prefix string. - test_fail(): prints a message after a test fails containing the test number of the failing test and the prefix. - test_pass(): prints a message after a test passes containing its test number and the prefix. - test_print(): prints the given formatted output string. - test_pass_pop(): runs test_pass() followed by prefix_pop(). - PREFIX_PUSH(): runs prefix_push(__func__). If the Memblock simulator was not compiled with VERBOSE=1, these functions/macros do nothing. Add the assert wrapper macros ASSERT_EQ(), ASSERT_NE(), and ASSERT_LT(). If the assert condition fails, these macros call test_fail() before executing assert().

memblock tests: add simulation of physical memory with multiple NUMA nodes Add function setup_numa_memblock() for setting up a memory layout with multiple NUMA nodes in a previously allocated dummy physical memory. This function can be used in place of setup_memblock() in tests that need to simulate a NUMA system. setup_numa_memblock(): - allows for setting up a memory layout by specifying the fraction of MEM_SIZE in each node Set CONFIG_NODES_SHIFT to 4 when building with NUMA=1 to allow for up to 16 NUMA nodes.

memblock tests: add simulation of physical memory with multiple NUMA nodes Add function setup_numa_memblock() for setting up a memory layout with multiple NUMA nodes in a previously allocated dummy physical memory. This function can be used in place of setup_memblock() in tests that need to simulate a NUMA system. setup_numa_memblock(): - allows for setting up a memory layout by specifying the fraction of MEM_SIZE in each node Set CONFIG_NODES_SHIFT to 4 when building with NUMA=1 to allow for up to 16 NUMA nodes.

memblock tests: Add simulation of physical memory Allocation functions that return virtual addresses (with an exception of _raw variant) clear the allocated memory after reserving it. This requires valid memory ranges in memblock.memory. Introduce memory_block variable to store memory that can be registered with memblock data structure. Move assert.h and size.h includes to common.h to share them between the test files.

memblock tests: add memblock_reserve_many_may_conflict_check() This may trigger the case fixed by commit 48c3b583bbdd ("mm/memblock: fix overlapping allocation when doubling reserved array"). This is done by adding the 129th reserve region into memblock.memory. If memblock_double_array() use this reserve region as new array, it fails.

memblock tests: update tests to check if memblock_alloc zeroed memory Add an assert in memblock_alloc() tests where allocation is expected to occur. The assert checks whether the entire chunk of allocated memory is cleared. The current memblock_alloc() tests do not check whether the allocated memory was zeroed. memblock_alloc() should zero the allocated memory since it is a wrapper for memblock_alloc_try_nid().

If the Memblock simulator was compiled with VERBOSE=1: - prefix_push(): appends the given string to a prefix string that will be printed in test_fail() and test_pass*(). - prefix_pop(): removes the last prefix from the prefix string. - prefix_reset(): clears the prefix string. - test_fail(): prints a message after a test fails containing the test number of the failing test and the prefix. - test_pass(): prints a message after a test passes containing its test number and the prefix. - test_print(): prints the given formatted output string. - test_pass_pop(): runs test_pass() followed by prefix_pop(). - PREFIX_PUSH(): runs prefix_push(__func__). If the Memblock simulator was not compiled with VERBOSE=1, these functions/macros do nothing. Add the assert wrapper macros ASSERT_EQ(), ASSERT_NE(), and ASSERT_LT().

memblock test: Add test to memblock_add() 129th region Add 129th region into the memblock, and this will trigger the memblock_double_array() function, this needs valid memory regions. So using dummy_physical_memory_init() to allocate a large enough memory region, and split it into a large enough memory which can be choosed by memblock_double_array(), and the left memory will be split into small memory region, and add them into the memblock. It make sure the memblock_double_array() will always choose the valid memory region that is allocated by the dummy_physical_memory_init(). So memblock_double_array() must success. Another thing should be done is to restore the memory.regions after memblock_double_array(), due to now the memory.regions is pointing to a memory region allocated by dummy_physical_memory_init(). And it will affect the subsequent tests if we don't restore the memory region. So simply record the origin region, and restore it after the test.
