xtensa: use correct symbol for the end of .rodata

2019-10-21T06:48:29Z

Use correct symbol for the end of .rodata section when dumping virtual memory layout. This fixes odd rodata size with XIP kernel. Signed-off-by: Max Filippov

xtensa: remove free_initrd_mem

2019-08-27T01:19:04Z

The xtensa free_initrd_mem() verifies that initrd is mapped and then frees its memory using free_reserved_area(). The initrd is considered mapped when its memory was successfully reserved with mem_reserve(). Resetting initrd_start to 0 in case of mem_reserve() failure allows to switch to generic free_initrd_mem() implementation.

xtensa: One function call less in bootmem_init()

2019-07-05T19:02:37Z

Avoid an extra function call by using a ternary operator instead of a conditional statement for a setting selection. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Message-Id: <495c9f2e-7880-ee9a-5c61-eee598bb24c2@web.de> Signed-off-by: Max Filippov

init: provide a generic free_initmem implementation

2019-05-14T16:47:47Z

Patch series "provide a generic free_initmem implementation", v2. Many architectures implement free_initmem() in exactly the same or very similar way: they wrap the call to free_initmem_default() with sometimes different 'poison' parameter. These patches switch those architectures to use a generic implementation that does free_initmem_default(POISON_FREE_INITMEM). This was inspired by Christoph's patches for free_initrd_mem [1] and I shamelessly copied changelog entries from his patches :) [1] https://lore.kernel.org/lkml/20190213174621.29297-1-hch@lst.de/ This patch (of 2): For most architectures free_initmem just a wrapper for the same free_initmem_default(-1) call. Provide that as a generic implementation marked __weak.

2018-10-15T19:36:20Z

ZONE_DMA is intended for magic < 32-bit pools (usually ISA DMA), which isn't required on xtensa. Move all the non-highmem memory into ZONE_NORMAL instead to match other architectures. Signed-off-by: Christoph Hellwig Signed-off-by: Max Filippov

xtensa: fix high memory/reserved memory collision

2018-02-15T17:46:42Z

Xtensa memory initialization code frees high memory pages without checking whether they are in the reserved memory regions or not. That results in invalid value of totalram_pages and duplicate page usage by CMA and highmem. It produces a bunch of BUGs at startup looking like this: BUG: Bad page state in process swapper pfn:70800 page:be60c000 count:0 mapcount:-127 mapping: (null) index:0x1 flags: 0x80000000() raw: 80000000 00000000 00000001 ffffff80 00000000 be60c014 be60c014 0000000a page dumped because: nonzero mapcount Modules linked in: CPU: 0 PID: 1 Comm: swapper Tainted: G B 4.16.0-rc1-00015-g7928b2cbe55b-dirty #23 Stack: bd839d33 00000000 00000018 ba97b64c a106578c bd839d70 be60c000 00000000 a1378054 bd86a000 00000003 ba97b64c a1066166 bd839da0 be60c000 ffe00000 a1066b58 bd839dc0 be504000 00000000 000002f4 bd838000 00000000 0000001e Call Trace: [] bad_page+0xac/0xd0 [] free_pages_check_bad+0x34/0x4c [] __free_pages_ok+0xae/0x14c [] __free_pages+0x30/0x64 [] init_cma_reserved_pageblock+0x35/0x44 [] cma_init_reserved_areas+0xf4/0x148 [] do_one_initcall+0x80/0xf8 [] kernel_init_freeable+0xda/0x13c [] kernel_init+0x9/0xd0 [] ret_from_kernel_thread+0xc/0x18 Only free high memory pages that are not reserved.
