+Subject: gcc-plugins: Reorganize gimple includes for GCC 13
+
+The gimple-iterator.h header must be included before gimple-fold.h
+starting with GCC 13. Reorganize gimple headers to work for all GCC
+versions.

+Subject: ata: ahci: fix enum constants for gcc-13
+
+gcc-13 slightly changes the type of constant expressions that are defined
+in an enum, which triggers a compile time sanity check in libata:
+
+linux/drivers/ata/libahci.c: In function 'ahci_led_store':
+linux/include/linux/compiler_types.h:357:45: error: call to '__compiletime_assert_302' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long)
+357 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
+
+The new behavior is that sizeof() returns the same value for the
+constant as it does for the enum type, which is generally more sensible
+and consistent.
+
+The problem in libata is that it contains a single enum definition for
+lots of unrelated constants, some of which are large positive (unsigned)
+integers like 0xffffffff, while others like (1<<31) are interpreted as
+negative integers, and this forces the enum type to become 64 bit wide
+even though most constants would still fit into a signed 32-bit 'int'.
+
+Fix this by changing the entire enum definition to use BIT(x) in place
+of (1<<x), which results in all values being seen as 'unsigned' and
+fitting into an unsigned 32-bit type.

+Subject: gcc-plugins: drop -std=gnu++11 to fix GCC 13 build
+
+The latest GCC 13 snapshot (13.0.1 20230129) gives the following:
+```
+cc1: error: cannot load plugin ./scripts/gcc-plugins/randomize_layout_plugin.so
+ :./scripts/gcc-plugins/randomize_layout_plugin.so: undefined symbol: tree_code_type
+```
+
+This ends up being because of https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=b0241ce6e37031
+upstream in GCC which changes the visibility of some types used by the kernel's
+plugin infrastructure like tree_code_type.
+
+After discussion with the GCC folks, we found that the kernel needs to be building
+plugins with the same flags used to build GCC - and GCC defaults to gnu++17
+right now. The minimum GCC version needed to build the kernel is GCC 5.1
+and GCC 5.1 already defaults to gnu++14 anyway, so just drop the flag, as
+all GCCs that could be used to build GCC already default to an acceptable
+version which was >= the version we forced via flags until now.

+Subject: block/blk-iocost (gcc13): keep large values in a new enum
+
+Since gcc13, each member of an enum has the same type as the enum [1]. And
+that is inherited from its members. Provided:
+  VTIME_PER_SEC_SHIFT     = 37,
+  VTIME_PER_SEC           = 1LLU << VTIME_PER_SEC_SHIFT,
+  ...
+  AUTOP_CYCLE_NSEC        = 10LLU * NSEC_PER_SEC,
+the named type is unsigned long.
+
+This generates warnings with gcc-13:
+  block/blk-iocost.c: In function 'ioc_weight_prfill':
+  block/blk-iocost.c:3037:37: error: format '%u' expects argument of type 'unsigned int', but argument 4 has type 'long unsigned int'
+
+  block/blk-iocost.c: In function 'ioc_weight_show':
+  block/blk-iocost.c:3047:34: error: format '%u' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int'
+
+So split the anonymous enum with large values to a separate enum, so
+that they don't affect other members.

+Subject: blk-iocost: avoid 64-bit division in ioc_timer_fn
+
+The behavior of 'enum' types has changed in gcc-13, so now the
+UNBUSY_THR_PCT constant is interpreted as a 64-bit number because
+it is defined as part of the same enum definition as some other
+constants that do not fit within a 32-bit integer. This in turn
+leads to some inefficient code on 32-bit architectures as well
+as a link error:
+
+arm-linux-gnueabi/bin/arm-linux-gnueabi-ld: block/blk-iocost.o: in function `ioc_timer_fn':
+blk-iocost.c:(.text+0x68e8): undefined reference to `__aeabi_uldivmod'
+arm-linux-gnueabi-ld: blk-iocost.c:(.text+0x6908): undefined reference to `__aeabi_uldivmod'
+
+Split the enum definition to keep the 64-bit timing constants in
+a separate enum type from those constants that can clearly fit
+within a smaller type.
