Enum constants can be used as array sizes; if the enum itself does not appear in the symbol expansion, a change in the enum constant will go unnoticed. Example patch that changes the ABI but does not change the checksum with current genksyms: | enum e { | E1, | E2, |+ E3, | E_MAX | }; | | struct s { | int a[E_MAX]; | } | | int f(struct s *s) { ... } | EXPORT_SYMBOL(f) Therefore, remember the value of each enum constant and expand each occurence to <constant> <value>. The value is not actually computed, but instead an expression in the form (last explicitly assigned value) + N is used. This avoids having to parse and semantically understand whole of C. Note: The changes won't take effect until the lexer and parser are rebuilt by the next patch. Signed-off-by:Michal Marek <mmarek@suse.cz> Acked-by:

Starting from perf_event_alloc()->perf_init_event(), the kernel assumes that event->cpu is either -1 or the valid CPU number. Change perf_event_alloc() to validate this argument early. This also means we can remove the similar check in find_get_context(). Signed-off-by:

If task == NULL, find_get_context() should always check that cpu is correct. Afaics, the bug was introduced by 38a81da2 "perf events: Clean up pid passing", but even before that commit "&& cpu != -1" was not exactly right, -ESRCH from find_task_by_vpid() is not accurate. Signed-off-by:

While most users of a physical Malta board are using the serial port as the console, a lot of QEMU users would prefer to interact with a graphical console. Enable the Cirrus FB support in the Malta default configuration to make that possible. Note that the default console will still be the serial port, users have to pass "console=tty0" to the kernel to use the Cirrus FB. Signed-off-by:

Just do what everyone else is doing by placing __read_mostly things in the .data.read_mostly section. mips_io_port_base can not be read-only (const) and writable (__read_mostly) at the same time. One of them has to go, so I chose to eliminate the __read_mostly. It will still get stuck in a portion of memory that is not adjacent to things that are written, and thus not be on a dirty cache line, for whatever that is worth. Signed-off-by:

This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches. Signed-off-by:

On the off chance that uasm ever warns about overflow, there is no way to know what the offending instruction is. Change the printks to WARNs, so we can get a nice stack trace. It has the added benefit of being much more noticeable than the short single line warning message, so is less likely to be ignored. Signed-off-by:

This patch adds a generic solution to support multiple machines based on a given SoC within a single kernel image. It is implemented already for several other architectures but MIPS has no generic support for that yet. [Ralf: This competes with DT but DT is a much more complex solution and this code has been used by OpenWRT for a long time so for now DT is a bad reason to stop the merge but longer term this should be migrated to DT.] Signed-off-by:
