A simple search over the kernel souce displays a number of correctly defined multiline macro, which generally are used as an array element initializer: % find ../linux -type f | xargs grep -B1 -H '^[:space]*\[.*\\$' However checkpatch.pl unexpectedly complains about all these macro definitions: % ./scripts/checkpatch.pl --types COMPLEX_MACRO -f include/linux/perf/arm_pmu.h ERROR: Macros with complex values should be enclosed in parentheses +#define PERF_MAP_ALL_UNSUPPORTED \ + [0 ... PERF_COUNT_HW_MAX - 1] = HW_OP_UNSUPPORTED The change intends to fix this type of false positives by flattening only array members and skipping array element designators. Signed-off-by:

The current test excludes any macro with ## concatenation from being reported with hidden flow control. Some macros are used with return or goto statements along with ##args or ##__VA_ARGS__. A somewhat common case is a logging macro like pr_info(fmt, ...) then a return or goto statement. Check the concatenated variable for args or __VA_ARGS__ and allow those macros to also be reported when they contain a return or goto. Signed-off-by:

So add a test that looks for constants that are cast to standard C90 int or longer types and suggest using C90 "6.4.4.1 Integer constants" integer-suffixes instead.

The clz table (__clz_tab) in lib/clz_tab.c is also provided as part of libgcc.a, and many architectures link against libgcc. To allow the linker to avoid a multiple-definition link failure, clz_tab.o has to be in lib/lib.a rather than lib/builtin.o. The specific issue is that libgcc.a comes before lib/builtin.o on vmlinux.o's link command line, so its _clz.o is pulled to satisfy __clz_tab, and then when the remainder of lib/builtin.o is pulled in to satisfy all the other dependencies, the __clz_tab symbols conflict. By putting clz_tab.o in lib.a, the linker can simply avoid pulling it into vmlinux.o when this situation arises. The definitions of __clz_tab are the same in libgcc.a and in the kernel; arguably we could also simply rename the kernel version, but it's unlikely the libgcc version will ever change to become incompatible, so just using it seems reasonably safe.

After processing by hex_dump_to_buffer() check all the parts to be expected. Part 1. The actual expected hex dump with or without ASCII part. Part 2. Check if the buffer is dirty beyond needed. Part 3. Return code should be as expected. This is done by using comparison of the return code and memcmp() against the test buffer. We fill the buffer by FILL_CHAR ('#') characters, so, we expect to have a tail of the buffer will be left untouched. The terminating NUL is also checked by memcmp(). Signed-off-by: -

Define a character to fill the test buffers. Though the character should be printable since it's used when errors are reported. It should neither be from hex digit [a-fA-F0-9] dictionary nor space. It is recommended not to use one which is present in ASCII part of the test data. Later on we might switch to unprintable character to make test case more robust. Signed-off-by:

The test suite currently doesn't cover many corner cases when hex_dump_to_buffer() runs into overflow. Refactor and amend test suite to cover most of the cases. This patch (of 9): Just to follow the scheme that most of the test modules are using. There is no fuctional change. Signed-off-by:

Some drivers need to read data out of iomem areas 32-bits at a time. Add an API to do this. Signed-off-by:
-
Stephen Boyd authored
The SMD driver is reading and writing chunks of data to iomem, and there's an __iowrite32_copy() function for the writing part, but no __ioread32_copy() function for the reading part. This series adds __ioread32_copy() and uses it in two places. This patch (of 4): The frv port uses compiler builtins, __builtin_read*(), for the I/O read routines. Unfortunately, these don't accept const void pointers although the generic ASM implementations do, so generic code passing const pointers to these APIs cause compilers to emit warnings. Add wrapper functions that cast away the const to avoid the warnings. Signed-off-by:

It was noticed that we lose precision in the final calculation for some inputs. The most egregious example is size=3000 blk_size=1900 in units of 10 should yield 5.70 MB but in fact yields 3.00 MB (oops). This is because the current algorithm doesn't correctly account for all the remainders in the logarithms. Fix this by doing a correct calculation in the remainders based on napier's algorithm. Additionally, now we have the correct result, we have to account for arithmetic rounding because we're printing 3 digits of precision. This means that if the fourth digit is five or greater, we have to round up, so add a section to ensure correct rounding. Finally account for all possible inputs correctly, including zero for block size. Fixes: b9f28d86Signed-off-by:

The problem is that get_maintainer.pl doesn't work if you have a ./ prefix on the filename. For example, if you type: ./scripts/get_maintainer.pl -f ./drivers/usb/usb-skeleton.c then the current code only includes LKML and people from the git log, it doesn't include Greg or the linux-usb list.

record_obj() in migrate_zspage() does not preserve handle's HANDLE_PIN_BIT, set by find_aloced_obj()->trypin_tag(), and implicitly (accidentally) un-pins the handle, while migrate_zspage() still performs an explicit unpin_tag() on the that handle. This additional explicit unpin_tag() introduces a race condition with zs_free(), which can pin that handle by this time, so the handle becomes un-pinned. Schematically, it goes like this: CPU0 CPU1 migrate_zspage find_alloced_obj trypin_tag set HANDLE_PIN_BIT zs_free() pin_tag() obj_malloc() -- new object, no tag record_obj() -- remove HANDLE_PIN_BIT set HANDLE_PIN_BIT unpin_tag() -- remove zs_free's HANDLE_PIN_BIT The race condition may result in a NULL pointer dereference: Unable to handle kernel NULL pointer dereference at virtual address 00000000 CPU: 0 PID: 19001 Comm: CookieMonsterCl Tainted: PC is at get_zspage_mapping+0x0/0x24 LR is at obj_free.isra.22+0x64/0x128 Call trace: get_zspage_mapping+0x0/0x24 zs_free+0x88/0x114 zram_free_page+0x64/0xcc zram_slot_free_notify+0x90/0x108 swap_entry_free+0x278/0x294 free_swap_and_cache+0x38/0x11c unmap_single_vma+0x480/0x5c8 unmap_vmas+0x44/0x60 exit_mmap+0x50/0x110 mmput+0x58/0xe0 do_exit+0x320/0x8dc do_group_exit+0x44/0xa8 get_signal+0x538/0x580 do_signal+0x98/0x4b8 do_notify_resume+0x14/0x5c This patch keeps the lock bit in migration path and update value atomically.

For THP=n, HPAGE_PMD_NR in smaps_account() expands to BUILD_BUG(). That's fine since this codepath is eliminated by modern compilers.
